    Upgrading the Switch Software Finding the Software Version and Feature Set The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. A subdirectory contains the files needed for web management. The image is stored on the system board flash device (flash:).

  • Page 5: Upgrading A Switch By Using The Device Manager" Section

    Upgrading the Switch Software Although you can copy any file on the flash memory to the TFTP server, it is time consuming to copy Note all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and archive it on an internal host in your network.

  • Page 6: Recovering From A Software Failure" Section

    Installation Notes The /overwrite option overwrites the software image in flash memory with the downloaded one. The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved. For //location, specify the IP address of the TFTP server. For /directory/image-name.tar, specify the directory (optional) and the image to download.

  • Page 7: Cisco Ios Limitations" Section

    Limitations and Restrictions Limitations and Restrictions 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.

  • Page 8: Ethernet" Section

    Limitations and Restrictions 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.

  • Page 9: Mac Addressing Multicasting" Section

    Limitations and Restrictions MAC Addressing Multicasting These are the multicasting limitations: If the number of multicast routes and Internet Group Management Protocol (IGMP) groups are more • than the maximum number specified by the show sdm prefer global configuration command, the traffic received on unknown groups is flooded in the received VLAN even though the show ip igmp snooping multicast-table privileged EXEC command output shows otherwise.

  • Page 10: Qos" Section

    Limitations and Restrictions number of interfaces configured with the logging event-spanning-tree interface configuration command. This condition adversely affects how the switch operates and could cause problems such as STP convergence delay. High CPU utilization can also occur with other conditions, such as when debug messages are logged at a high rate to the console.

  • Page 11: Device Manager Limitations" Section

    Important Notes Trunking These are the trunking limitations: The switch treats frames received with mixed encapsulation (IEEE 802.1Q and Inter-Switch Link • [ISL]) as frames with FCS errors, increments the error counters, and the port LED blinks amber. This happens when an ISL-unaware device receives an ISL-encapsulated packet and forwards the frame to an IEEE 802.1Q trunk interface.
  • Page 12 Important Notes Cisco IOS Notes These notes apply to Cisco IOS software: Cisco IOS Release 12.2(40)SE1 and later • If the switch has interfaces with automatic QoS for voice over IP (VoIP) configured and you upgrade the switch software to Cisco IOS Release 12.2(40)SE1 (or later), when you enter the auto qos voip cisco-phone interface configuration command on another interface, you might see this message: AutoQoS Error: ciscophone input service policy was not properly applied policy map AutoQoS-Police-CiscoPhone not configured...

  • Page 15 Open Caveats CSCsd60718 • When you enter the no speed interface configuration command, the Ethernet interface speed does not return to its default setting. This affects interfaces Gi0/17 to Gi0/20, Gi0/23, and Gi0/24. This does not affect interfaces Gi0/21 and Gi0/22. The workaround is either to enter the speed interface configuration command auto keyword to change the interface speed to the default setting or to explicitly set the speed.
  • Page 16 Open Caveats CSCsi63999 • Changing the spanning tree mode from rapid STP to MSTP can cause tracebacks when the virtual port error-disable feature is enabled when the STP mode is changed. There is no workaround. CSCsj21718 • When system jumbo MTU size is configured on a switch and the egress ports can support jumbo frames, the egress SPAN jumbo frames are not forwarded to the SPAN destination ports.

    Resolved Caveats Resolved Caveats These sections describe the caveats that have been resolved in this release: CSCse06827 • When dynamic ARP inspection is configured on a VLAN, and the ARP traffic on a port in the VLAN is within the configured rate limit, the port might go into an error-disabled state. The workaround is to configure the burst interval to more than 1 second.

Every port in a private VLAN is a • member of the primary VLAN. The primary VLAN carries unidirectional traffic downstream from the promiscuous ports to the (isolated and community) host ports and to other promiscuous ports.
  • Page 26 Documentation Updates Private VLANs across Multiple Switches As with regular VLANs, private VLANs can span multiple switches. A trunk port carries the primary VLAN and secondary VLANs to a neighboring switch. The trunk port treats the private VLAN as any other VLAN.
  • Page 27 Documentation Updates Private VLANs and Unicast, Broadcast, and Multicast Traffic In regular VLANs, devices in the same VLAN can communicate with each other at the Layer 2 level, but devices connected to interfaces in different VLANs must communicate at the Layer 3 level. In private VLANs, the promiscuous ports are members of the primary VLAN, while the host ports belong to secondary VLANs.
