The system requirements are described in these sections:. Table 1 lists the hardware supported on this release. Each uplink port is considered a single interface with dual front ends RJ connector and SFP module slot. The dual front ends are not redundant interfaces, and only one port of the pair is active. Cisco EtherSwitch service module. These sections describes the hardware and software requirements for using the device manager:.
Table 2 lists the minimum hardware requirements for running the device manager. Table 2 Minimum Hardware Requirements. Intel Pentium II 8. Table 3 lists the supported operating systems and browsers for using the device manager. The device manager verifies the browser version when starting a session to ensure that the browser is supported.
Note The device manager does not require a plug-in. Table 3 Supported Operating Systems and Browsers. Service Pack 1 or higher is required for Internet Explorer 5. You cannot create and manage switch clusters through the device manager.
To create and manage switch clusters, use the command-line interface CLI or the Network Assistant application. When creating a switch cluster or adding a switch to a cluster, follow these guidelines:. Cisco IOS These are the procedures for downloading software. Before downloading software, read this section for important information:. A subdirectory contains the files needed for web management. The image is stored on the system board flash device flash:.
You can use the show version privileged EXEC command to see the software version that is running on your switch. The second line of the display shows the version. Note For Catalyst and switches and the Cisco EtherSwitch service modules, although the show version output always shows the software image running on the switch, the model name shown at the end of this display is the factory configuration IP base image [formerly known as the SMI] or IP services image [formerly known as the EMI] and does not change if you upgrade the software image.
You can also use the dir filesystem : privileged EXEC command to see the directory names of other software images that you might have stored in flash memory. The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file.
This file contains the Cisco IOS image file and the files needed for the embedded device manager. You must use the combined tar file to upgrade the switch through the device manager. The image that provides full Layer 3 routing and advanced services was referred to as the enhanced multilayer image EMI. Table 5 lists the filenames for this software release. Catalyst IP base image and device manager files. This image also runs on the Cisco EtherSwitch service modules. Catalyst IP services image and device manager files.
Catalyst IP base cryptographic image and device manager files. Catalyst IP services cryptographic image and device manager files. Catalyst advanced IP services image, cryptographic file, and device manager files. Catalyst IP base image file and device manager files.
Catalyst image file and device manager files. Catalyst cryptographic image file and device manager files. This image has the Kerberos and SSH features. The switch and the internal controller run separate software versions, which must be upgraded separately. If the image versions are not compatible, the wireless LAN controller switch could stop functioning.
Table 6 is the compatibility matrix for Catalyst and wireless controller. Before upgrading your switch software, make sure that you have archived copies of the current Cisco IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and until you have verified that the new Cisco IOS image works properly in your network.
See Product Bulletin for more information:. You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a host by using the copy flash: tftp: privileged EXEC command. We recommend that you download the tar file from Cisco. You can also configure the switch as a TFTP server to copy files from one switch to another without using an external TFTP server by using the tftp-server global configuration command.
You can upgrade switch software by using the device manager or Network Assistant. For detailed instructions, click Help. Note When using the device manager to upgrade your switch, do not use or close your browser session after the upgrade process begins. Wait until after the upgrade process completes. This procedure is for copying the combined tar file to the switch.
You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace or keep the current image. Step 1 Use Table 5 to identify the file that you want to download. Step 2 Download the software image file. If you have a SmartNet support contract, go to this URL, and log in to download the appropriate files:. To download the image for a Catalyst switch, click Catalyst software.
To obtain authorization and to download the cryptographic software files, click Catalyst 3DES Cryptographic Software.
For more information, see Appendix B in the software configuration guide for this release. Step 4 Log into the switch through the console port or a Telnet session.

If you are installing the same version of software that is currently on the switch, overwrite the current image by entering this privileged EXEC command:. Directory and image names are case sensitive. This example shows how to download an image from a TFTP server at You can assign IP information to your switch by using these methods:. These sections describe the new supported hardware and the new and updated software features provided in this release:. There are no new hardware features for this release.
These sections describe the new software features for this release:. These are the new features for the Catalyst , , , and switches:. These are the new features for the Catalyst and switches.
Table 7 lists the minimum software release required to support the major features of the Catalyst , , , and switches and the Cisco EtherSwitch service modules. Multicast virtual routing and forwarding VRF lite. Support for auto rendezvous point auto-RP for multicast. Generic online diagnostics to test the hardware functionality of the supervisor engine. Stack MAC persistent timer and archive download enhancements. Support for configuring an IEEE IEEE Layer 2 point-to-point tunneling and Layer 2 point-to-point tunneling bypass.
Support for SSL version 3. Cisco intelligent power management to limit the power allowed on a port, or pre-allocate reserve power for a port. Software upgrade device manager or Network Assistant only. You should review this section before you begin working with the switch. These are known limitations that will not be fixed, and there is not always a workaround.
Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software.
Unless otherwise noted, these limitations apply to the Catalyst , , , and switches and the Cisco EtherSwitch service modules:. These are the configuration limitations:. This problem occurs under these conditions:. The workaround is to reconfigure the static IP address. Change the routed port to a nonrouted port or the reverse. Re-enable auto-QoS on the interface. If the file is manually removed from the file system, the DHCP snooping database does not create another database file.
You need to disable the DHCP snooping database and enable it again to create the database file. No workaround is necessary; these are the designed behaviors. When you enter the show ip arp inspection log privileged EXEC command, the log entries from all switches in the stack are moved to the switch on which you entered the command. The workaround is to enter the no switchport block unicast interface configuration command on that specific interface. There is no workaround. This is a cosmetic error and does not affect the functionality of the switch.
To change the baud rate, reload the Cisco EtherSwitch service module with the bootloader prompt. You can then change the baud rate and change the speed on the TTY line of the router connected to the Cisco EtherSwitch Service module console.
The workaround is to use switch ports other than those specified for redundancy and for applications that immediately detect active links. High CPU utilization can also occur with other conditions, such as when debug messages are logged at a high rate to the console. The workaround is to configure aggressive UDLD.
If the Cisco EtherSwitch service module is in access mode, the workaround is to enter the spanning-tree portfast interface configuration command on the internal Gigabit Ethernet interface. If the service module is in trunk mode, there is no workaround. If this happens, uneven traffic distribution will happen on EtherChannel ports. Changing the load balance distribution method or changing the number of ports in the EtherChannel can resolve this problem.
Use any of these workarounds to improve EtherChannel load balancing:. For example, with load balance configured as dst-ip with distinct incrementing destination IP addresses, and the number of ports in the EtherChannel set to either 2, 4, or 8, load distribution is optimal.
When the active switch fails in a switch cluster that uses HSRP redundancy, the new active switch might not contain a full cluster member list. The workaround is to ensure that the ports on the standby cluster members are not in the spanning-tree blocking state. The workaround for networks with pre-standard powered devices is to leave the maximum wattage set at the default value You can also configure the maximum wattage for the port for no less than the value the powered device reports as the power consumption through CDP messages.
For networks with IEEE Class 0, 3, or 4 devices, do not configure the maximum wattage for the port at less than the default The workaround is to enable PoE and to configure the switch to recover from the PoE error-disabled state. CiscoWorks is not supported on the Catalyst FS switch. The switchport block multicast interface configuration command is only applicable to non-IP multicast traffic. The workaround is to enter the clear ip mroute privileged EXEC command on the interface.
After you configure a switch to join a multicast group by entering the ip igmp join-group group-address interface configuration command, the switch does not receive join packets from the client, and the switch port connected to the client is removed from the IGMP snooping forwarding table.
The workaround is to enable IP routing or to disable multicast routing on the switch. You can also use the ip igmp snooping querier global configuration command if IP multicast routing is enabled for queries on a multicast router port. These are the powers limitation for the Cisco EtherSwitch service modules:.
You should use the power inline never interface configuration command on Cisco EtherSwitch service module ports that are not connected to PoE devices. This is not a problem because the display correctly shows the total used power and the remaining power available on the system. Created by Emmanuel Tychon on AM.

You need to disable the DHCP snooping database and enable it again to create the database file.
No workaround is necessary; these are the designed behaviors. The workaround is to configure the port for 10 Mbps and half duplex or to connect a hub or a nonaffected device to the switch. When you enter the show ip arp inspection log privileged EXEC command, the log entries from all switches in the stack are moved to the switch on which you entered the command.

This is not a problem because the display correctly shows the total used power and the remaining power available on the system.
The workaround is to enter the shutdown and the no shutdown interface configuration commands on the Fast Ethernet interface of a new IP phone that is attached to the service module port after the internal link is brought up.
These are the quality of service QoS limitations:. This error message means there is a temporary memory shortage that normally recovers by itself. You can verify that the switch stack has recovered by entering the show cef line user EXEC command and verifying that the line card states are up and sync.
No workaround is required because the problem is self-correcting. The workaround is to change any one of the listed conditions. This is a hardware limitation and only applies to these switches CSCdy :. This is a hardware limitation and only applies to these switches CSCea :.
These are the Catalyst and Cisco EtherSwitch service module switch stack limitations:. This occurs after a stack master re-election when the previous stack master was running the IP services image formerly known as the EMI and the new stack master is running the IP base image formerly known as the SMI.
These are the workarounds. Only one of these is necessary:. This is the expected behavior of the offline configuration provisioning feature. The workaround is to reduce the number of VLANs or trunks. The workaround is to define another policy-map name for the second-level policy-map with the same configuration to be used for another policy-map. When you are prompted to accept the security certificate and you click No , you only see a blank screen, and the device manager does not launch.
The workaround is to click Yes when you are prompted to accept the certificate. These sections describe the important notes related to this software release for the Catalyst , , , and switches and for the Cisco EtherSwitch service modules:. From the Settings window, choose Automatically. Click OK to exit the Internet Options window. Configure the HTTP server interface for the type of authentication that you want to use.
You should write down the port number through which you are connected. Use care when changing the switch IP information. If you are not using the default method of authentication the enable password , you need to configure the HTTP server interface with the method of authentication used on the switch. This section describes the open caveats with possible unexpected activity in this software release.
Unless otherwise noted, these severity 3 Cisco IOS configuration caveats apply to the Catalyst , , , and switches and to Cisco EtherSwitch service modules:. However, when the dynamic MAC addresses are either manually or automatically removed due to a topology change or enabling or disabling the port security or IEEE Catalyst , , and switches do not populate the secure address-table with the source MAC address from CDP packets.
The workaround is that when using Cisco IP Phones with the fix for CSCed and port-security configured on the switchport, configure switches with one secure address for the phone, plus additional MAC addresses for any devices connected to the Cisco IP Phone.
Phone detection events that are generated by many IEEE phones connected to the switch ports can consume a significant amount of CPU time if the switch ports cannot power the phones because the internal link is down. The workaround is to enter the power inline never interface configuration command on all the Fast Ethernet ports that are not powered by but are connected to IP phones if the problem persists. A Catalyst ME running Release When connected to the router through an auxiliary port in a session to a Cisco EtherSwitch service module, the service module session fails when you enter the shutdown and the no shutdown interface configuration commands on the service module router interface.
A duplex mismatch occurs when two Fast Ethernet interfaces that are directly connected on two EtherSwitch service modules are configured as both Mbps and full duplex and as automatic speed and duplex settings.
If two Cisco EtherSwitch service modules are directly connected through Fast Ethernet interfaces configured as both Mbps and full duplex and as automatic speed and duplex settings, one interface might detect the other as a Cisco-powered device. When the router is rebooted after it is powered on approximately once in 10 to 15 reboots , the Router Blade Communication Protocol RBCP between the router and the EtherSwitch service module might not be reestablished, and this message appears:.
The workaround is to reload the EtherSwitch service module software without rebooting the router. If two or more switches in a stack of PoE switches restart at the same time and you enter the no switch stack-member-number provision global configuration command, this message appears on the console:. This problem does not affect the switch functionality. Unless otherwise noted, these resolved caveats apply to the Catalyst , , and switches:.
The packet must be sent from a local network segment. Only devices that have been explicitly configured to process IPv6 traffic are affected. Upon successful exploitation, the device may reload or be open to further exploitation.
Cisco has made free software available to address this vulnerability for all affected customers. Memory allocation malloc and remote-procedure call RPC throttle messages no longer appear when one or more large access control lists ACLs are pasted to the console window.
When redundant uplinks are from the same stack member in a switch stack and UplinkFast is configured, dummy multicast packets are no longer sent.
These attacks, which only affect sessions terminating or originating on a device itself, can be of three types:. Attacks that use ICMP "hard" error messages 2. Attacks that use ICMP "source quench" messages. Successful attacks may cause connection resets or reduction of throughput in existing connections, depending on the attack type. Multiple Cisco products are affected by the attacks described in this Internet draft. Cisco has made free software available to address these vulnerabilities.
In some cases there are workarounds available to mitigate the effects of the vulnerability. NISCC is working with multiple vendors whose products are potentially affected. If static IP source bindings are configured on an EtherChannel interface and the configuration is saved, the IP source bindings are no longer lost when the switch is reloaded. If Port Fast is enabled on the host ports and traffic is continuously received on that port, when a secondary VLAN is associated and then quickly disassociated, the MAC address tables across the switch stack no longer become unsynchronized.
An When In previous releases, the configuration would sometimes not appear until a link up occurred, or the configuration would not appear on remote ports in a switch.
When an When the default interface interface-id interface configuration command is entered on a tunnel interface, the configuration is now completely cleared.
After a stack master failover, any per-user access control lists ACLs applied on authenticated When you set the duplex mode by using SNMP, the changes now appear in the output of the show interface interface-id include duplex and the show running interface interface-id include duplex commands. When you enable The switch now generates an ARP request for the next policy-based routing PBR hop when it receives packets that should be policy routed.
The switch no longer restarts when you enter the auto qos voip cisco-phone interface configuration command. Both sides of a link no longer stay in the loop-inconsistent state under these conditions:. The port security MIB no longer issues a trap for a security violation for a port that is configured in the protect mode.
The "Configuring a System Name and Prompt" section and the "Configuring a System Prompt" section of the "Administering the Switch" chapter incorrectly state that you can manually configure the prompt global configuration command. The switches do not support this command. You should ignore this information in printed and online copies of the software configuration guides.
This is the correct information:. The switch also updates the entries in the binding file. The frequency at which the file is updated is based on a configurable delay, and the updates are batched. If the file is not updated in a specified time set by the write-delay and abort-timeout values , the update stops. Use the ip dhcp snooping binding privileged EXEC command when you are testing or debugging the switch.
To stop using the the database agent and bindings file, use the the no ip dhcp snooping database global configuration command. The description and usage guidelines for the ip dhcp snooping database global configuration command are incorrect. Use the no form of this command to disable the agent, to reset the timeout value, or to reset the write-delay value.

A switch no longer fails IEEE The switch now forwards an IEEE A switch no longer intermittently fails under these conditions:. The port channel is a routed port. In previous releases, the switch would fail, often preceded by this error message:. The line protocol for a member switch no longer goes down when the master switch reloads that member switch. Packets are no longer dropped when the mls qos queue-set output buffers global configuration command is configured with the values threshold and buffer in same queue.
In previous releases, the trap showed 2 , which means forwarding. When the radius-server source-ports global configuration command is removed, the switch no longer sends the RADIUS server requests with incorrect source ports. A switch no longer displays a traceback error during a stack master change under these conditions:.
In nonstandard VRRP packets, the Layer 3 destination is a multicast address, but the Layer 2 destination address is a unicast address. After you delete a global- or interface-level NAC Layer 2 IP configuration by using the no ip admission name global- or interface-configuration command, the switch no longer fails and displays a message similar to this:.
Symptoms: The VTP feature in certain versions of Cisco IOS software may be vulnerable to a crafted packet sent from the local network segment which may lead to denial of service condition.
Conditions: The packets must be received on a trunk enabled port. Further Information: On the 13th September , Phenoelit Group posted an advisory containing three vulnerabilities:. Symptoms: The VTP feature in certain versions of Cisco IOS software is vulnerable to a locally-exploitable buffer overflow condition and potential execution of arbitrary code.
Conditions: The packets must be received on a trunk enabled port, with a matching domain name and a matching VTP domain password if configured. The router crash recovery mechanism now works correctly. A switch no longer displays unnecessary output when the debug ip packet access-list privileged EXEC command is enabled.
A switch no longer reloads when a service policy is attached to one of the four SFP ports. The output of the show interfaces transceiver detail privileged EXEC command no longer shows incorrect values for the receive power and thresholds. When a supplicant authenticates, the switch no longer fails if a value for attribute 11 is configured on the RADIUS server. BackboneFast now works correctly when it is enabled on a stack of switches.
This section provides these updates to the product documentation for the Catalyst , , , and switches:. In these sections of the Catalyst and Catalyst software configuration guide:.
Note Though visible on all switches, this option is supported only when the stack is running the advanced IP services image. In the Catalyst and Catalyst command reference, this information is incorrect. In the sdm prefer global configuration and the show sdm prefer privileged EXEC commands, this information about the dual-ipv4-and-ipv6 option is incorrect:.
The dual-ipv4-and-ipv6 option is supported when the switch runs the IP base, IP services, or advanced IP services image. These are the documentation updates for this release:. This information was added to the R egulatory Compliance and Safety Information for the Catalyst , , , and switches:. Voice over IP VoIP service and the emergency calling service do not function if power fails or is disrupted. After power is restored, you might have to reset or reconfigure equipment to regain access to VoIP and the emergency calling service.

This is the documentation update for the software configuration guides for this release:. Note Storm control is supported on physical interfaces. You can also configure storm control on an EtherChannel. When storm control is configured on an EtherChannel, the storm control settings propagate to the EtherChannel physical interfaces.
This is the documentation update for the command references for this release:. We recommend that you configure the seconds and number parameters as follows:. The switch dynamically determines the default seconds value that is from 10 to 60 seconds. The switch dynamically determines the default tries value that is from 10 to This is the correct command syntax:.

We recommend Intel Pentium 4. Software Requirements Table 3 lists the supported operating systems and browsers for using the device manager. Microsoft Internet Explorer Cluster Compatibility You cannot create and manage switch clusters through the device manager. When creating a switch cluster or adding a switch to a cluster, follow these guidelines: When you create a switch cluster, we recommend configuring the highest-end switch in your cluster as the command switch.
If you are managing the cluster through Network Assistant, the switch with the latest software should be the command switch, unless your command switch is running Cisco IOS Release The standby command switch must be the same type as the command switch. For example, if the command switch is a Catalyst switch, all standby command switches must be Catalyst switches.
Upgrading the Switch Software These are the procedures for downloading software. Deciding Which Files to Use The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file.
To download software, follow these steps: Step 1 Use Table 5 to identify the file that you want to download. The bootloader can take up to 1 minute to upgrade the first time that the new software is loaded.
Do not power cycle the switch during the bootloader upgrade. Switch ping tftp-server-address. Installation Notes You can assign IP information to your switch by using these methods: The Express Setup program , as described in the switch getting started guide.
The CLI-based setup program, as described in the switch hardware installation guide. The DHCP-based autoconfiguration, as described in the switch software configuration guide. Manually assigning an IP address, as described in the switch software configuration guide.
Minimum Cisco IOS Release for Major Features Table 6 lists the minimum software release required to support the major features of the Catalyst , , , and switches and the Cisco EtherSwitch service modules. Limitations and Restrictions You should review this section before you begin working with the switch. This problem occurs under these conditions: — When the switch is booted without a configuration no config.
CSCec Catalyst or switches and Cisco EtherSwitch service modules When you change a port from a nonrouted port to a routed port or the reverse, the applied auto-QoS setting is not changed or updated when you verify it by using the show running interface or show mls qos interface user EXEC commands. These are the workarounds: 1. Disable auto-QoS on the interface. This is a hardware limitation.
CSCed When connected to some third-party devices that send early preambles, a switch port operating at Mbps full duplex or Mbps half duplex might bounce the line protocol up and down. The problem is observed only when the switch is receiving frames. Any log entries that are still in the log buffer have not been output as a system message on a switch that fails are lost. CSCed When port security is enabled on an interface in restricted mode and the switchport block unicast interface command has been entered on that interface, MAC addresses are incorrectly forwarded when they should be blocked The workaround is to enter the no switchport block unicast interface configuration command on that specific interface.
The console on the Cisco EtherSwitch service modules only supports three baud rates bps, bps, and bps and must be set at the bootloader prompt. The switch rejects a CLI command to change the baud rate. Packets arriving at these ports before the switch software is completely loaded are lost. This is a hardware limitation when the switch uses small form-factor pluggable SFP modules with copper connections.
If the internal Gigabit Ethernet interface on a Cisco EtherSwitch service module connected to the router is configured as a switch port in access mode or in trunk mode, the internal link is not operational until it reaches the STP forwarding state. Therefore, the PoE that comes from the host router is also not available until the internal Gigabit Ethernet link reaches the STP forwarding state.
This is due to STP convergence time. This problem does not occur on routed ports.
