Upgrading the Switch Software Upgrading the Switch Software These are the procedures for downloading software.
PAGE 4
Upgrading the Switch Software Upgrading a Switch by Using the CLI This procedure is for copying the 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. The archive download-sw privileged EXEC command both downloads and extracts the files. To download the image for a CGESM switch, follow these steps: Step 1 Go to: http://www.hp.com/support and select the appropriate country or region.

Installation Notes Recovering from a Software Failure For recovery procedures, see the “Troubleshooting” chapter in the Cisco Gigabit Ethernet Switch Module for HP-Blade System p-Class Software Configuration Guide for this release. Installation Notes You can assign IP information to your switch by using these methods: • The Express Setup program, as described in the Cisco Gigabit Ethernet Switch Module for HP-Blade System p-Class Hardware Installation Guide.

Limitations and Restrictions Table 2 CGESM Switch Features and the Minimum Cisco IOS Release Required (continued) Feature Minimum Cisco IOS Release Required Support for auto rendezvous point (auto-RP) for multicast 12.2(37)SE Web authentication 12.2(35)SE Support for DSCP transparency 12.2(25)SE1 Support for VLAN-based QoS and hierarchical policy maps on SVIs 12.2(25)SE1 Device manager 12.2(25)SE1 Support for SSL version 3.0 for secure HTTP communication (cryptographic images only) 12.
PAGE 7
Limitations and Restrictions • “VLAN” section on page 10 Configuration These are the configuration limitations: • If you run the CLI-based setup program, the IP address that the Dynamic Host Configuration Protocol (DCHP) provides is reflected as a static IP address in the config.text file. The workaround is to not run setup if DHCP is required for your configuration. • If you start and then end the autoinstall program before the DHCP server replies, DHCP requests are ignored.
PAGE 8
Limitations and Restrictions • A traceback error occurs if a crypto key is generated after an SSL client session. There is no workaround. This is a cosmetic error and does not affect the functionality of the switch. (CSCef59331) • 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. There is no workaround.
PAGE 9
Limitations and Restrictions • If an IG MP report packet has two multicast group records, the switch removes or adds interfaces depending on the order of the records in the packet: – If the ALLOW_NEW_SOURCE record is before the BLOCK_OLD_SOURCE record, the switch removes the port from the group. – If the BLOCK_OLD_SOURCE record is before the ALLOW_NEW_SOURCE record, the switch adds the port to the group. There is no workaround.
PAGE 10
Limitations and Restrictions • During periods of very high traffic, when two RSPAN source sessions are configured, the VLAN ID of packets in one RSPAN session might overwrite the VLAN ID of the other RSPAN session. If this occurs, packets intended for one RSPAN VLAN are incorrectly sent to the other RSPAN VLAN. This problem does not affect RSPAN destination sessions. The workaround is to configure only one RSPAN source session.
PAGE 11
Important Notes Hardware Limitations and Restrictions This is the hardware limitation and restriction: When using CLC-T SFPs in CGESM switches, the SFP module can be installed too far into the switch. This can prevent links from operating properly. The workaround is to slightly pull the SFP out of the module slot.
PAGE 12
VLAN Interfaces and MAC Addresses 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 Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface: Command Purpose Step 1 configure terminal Enter global configuration mode.

Documentation Notes Documentation Notes This section describes documentation notes related to this IOS release. References to Cisco IOS Release 12.2(25)SE These older documents refer to Release 12.2(25)SE.

PAGE 14
Resolved Caveats • rQm 266129 If you power on a switch that does not have a config.txt file (the factory default file) and leave the switch on for few hours, the switch console appears to be stalled during setup. The workaround is to reload the switch before you continue to configure it.
PAGE 15
Documentation Updates • CSCta78502 When you have configured a login banner by entering the banner login c message c global configuration command and the switch reloads, the output of banner is missing a carriage return, making the format incorrect. There is no workaround. • CSCtb97439 When remote neighbors change, the LLDP MIB does not properly update the remote neighbors. The workaround is to clear the LLDP table by entering the clear lldp table privileged EXEC command.
