Cisco Gigabit Ethernet Switch Module for HP BladeSystem p-Class Release Notes, Cisco IOS Release 12.2(50)SE and later Revised August 13, 2009 These release notes include important information about this Cisco IOS release for the Cisco Gigabit Ethernet Switch Module (CGESM) for the HP BladeSystem p-Class. This document includes any limitations, restrictions, and caveats that apply to this release.
System Requirements • “Resolved Caveats” section on page 15 • “Documentation Updates” section on page 18 • “Related Documentation” section on page 22 • “Technical support” section on page 22 System Requirements The system requirements are described in these sections: • “Device Manager System Requirements” section on page 2 • “Cluster Compatibility” section on page 3 Device Manager System Requirements These sections describes the hardware and software requirements for using the device manager: •
Upgrading the Switch Software Software Requirements These are the supported operating systems and browsers for the device manager: • Windows 2000, XP, Vista, and Windows Server 2003. • Internet Explorer 5.5, 6.0, 7.0, Firefox 1.5, 2.0 or later. The device manager verifies the browser version when starting a session, and it does not require a plug-in. Cluster Compatibility You cannot create and manage switch clusters through the device manager.
Upgrading the Switch Software Deciding Which Files to Use The upgrade procedures in these release notes describe how to perform the upgrade by using a tar file. This file contains the Cisco IOS image file and the files needed for the embedded device manager. You must use the tar file to upgrade the switch through the device manager. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.
Installation Notes Step 8 (Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC command: ping tftp-server-address For more information about assigning an IP address and default gateway to the switch, refer to the software configuration guide for this release. Step 9 Download the image file from the TFTP server to the switch.
New Software Features New Software Features There are no new software features for this release. Minimum Cisco IOS Release for Major Features Table 2 lists the minimum software release required to support the major features on this switch. Table 2 CGESM Switch Features and the Minimum Cisco IOS Release Required Feature Minimum Cisco IOS Release Required Generic message authentication support with the SSH Protocol and compliance with RFC 4256. 12.2(46)SE IPv6 default router preference (DRP) 12.
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.
Limitations and Restrictions The workaround is to reconfigure the static IP address. (CSCea71176 and CSCdz11708) • 1. Disable auto-QoS on the interface. 2. Change the routed port to a nonrouted port or the reverse. 3. Re-enable auto-QoS on the interface. (CSCec44169) The DHCP snooping binding database is not written to flash or a remote file in either of these situations: – The DHCP snooping database file is manually removed from the file system.
Limitations and Restrictions IP When the rate of received DHCP requests exceeds 2,000 packets per minute for a long time, the response time might be slow when you are using the console. The workaround is to use rate limiting on DHCP traffic to prevent a denial of service attack from occurring. (CSCeb59166) IP Telephony This is the IP telephony limitation: After you change the access VLAN on a port that has 802.1x enabled, the IP Phone address is removed. Because learning is restricted on 802.
Limitations and Restrictions • When auto-QoS is enabled on the switch, priority queuing is not enabled. Instead, the switch uses shaped round robin (SRR) as the queuing mechanism. The auto-QoS feature is designed on each platform based on the feature set and hardware limitations, and the queuing mechanism supported on each platform might be different. There is no workaround. (CSCee22591) SPAN and RSPAN These are the SPAN and Remote SPAN (RSPAN) limitations.
Important Notes interface other than one in VLAN Y is sent on the trunk port in VLAN Y because the trunk port is forwarding in VLAN Y, even though the port has no group membership in VLAN Y. There is no workaround. (CSCdz42909) • For trunk ports or access ports configured with 802.1Q tagging, inconsistent statistics might appear in the show interfaces counters privileged EXEC command output. Valid 802.
Important Notes Cisco IOS Notes These notes apply to Cisco IOS software: • Cisco IOS Release 12.2(40)SE 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.
VLAN Interfaces and MAC Addresses Command Purpose Step 3 end Return to privileged EXEC mode. Step 4 show running-config Verify your entries. The device manager uses the HTTP protocol (the default is port 80) and the default method of authentication (the enable password) to communicate with the switch through any of its Ethernet ports and to allow switch management from a standard web browser.
Open Caveats Open Caveats Open IOS Caveats These severity 3 Cisco IOS configuration caveats apply to the CGESM switch: • CSCso96778 When you use the ipv6 address dhcp interface configuration command on an interface that is configured in router mode, other addresses on the prefix associated with the new address might not be accessible.
Resolved Caveats Resolved Caveats • “Cisco IOS Caveats Resolved in Cisco IOS Release 12.2(50)SE3” section on page 15 • “Cisco IOS Caveats Resolved in Cisco IOS Release 12.2(50)SE2” section on page 16 • “Cisco IOS Caveats Resolved in Cisco IOS Release 12.2(50)SE1” section on page 16 • “Cisco IOS Caveats Resolved in Cisco IOS Release 12.2(50)SE” section on page 16 Cisco IOS Caveats Resolved in Cisco IOS Release 12.
Resolved Caveats • CSCta56469 Moving a PC between two IP Phones without disconnecting either phone from the switch no longer triggers a port-security violation. • CSCta67777 A port security violation error no longer occurs when MAC address sticky learning is enabled on a port and a CDP is enabled on a connected IP Phone. Cisco IOS Caveats Resolved in Cisco IOS Release 12.2(50)SE2 • CSCsy72726 A switch running 12.
Resolved Caveats • CSCsd86177 When you remove and reconfigure a loopback interface, it now appears in the ifTable. • CSCse03859 DHCP snooping now works when the switch is in VTP server mode and VLANs with IDs greater than 255 (256 and above) are created. • CSCsq26873 The server no longer attempts re-authentication every ten minutes when a switch is configured with the dot1x timeout reauth-period server interface configuration command.
Documentation Updates • CSCsv89005 A switch configured with class-based policies that are applied and active on at least one interface no longer might reload or display CPU hog messages during SNMP polling for the ciscoCBQosMIB. • CSCsv91358 When you have entered the vlan dot1q tag native global configuration command to configure a switch to tag native VLAN frames on 802.1Q trunk ports, and you configure a new voice VLAN on an access port, the MAC address of a connected PC is now correctly relearned.
