Cisco Gigabit Ethernet Switch Module for HP BladeSystem p-Class Release Notes, Cisco IOS Release 12.2(25)SE1

• IP traffic with IP options set is sometimes leaked on a trunk port. For example, a trunk

port is a member of an IP multicast group in VLAN X but is not a member in VLAN Y.

If VLAN Y is the output interface for the multicast route entry assigned to the multicast

group and an interface in VLAN Y belongs to the same multicast group, the IP-option

traffic received on an input VLAN 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

802.1Q frames of 64 to 66 bytes are correctly forwarded even though the port LED blinks

amber, and the frames are not counted on the interface statistics. There is no workaround.

(CSCec35100)

VLAN

If the number of VLANs times the number of trunk ports exceeds the recommended limit of

13,000, the switch can fail. The workaround is to reduce the number of VLANs or trunks.

Device Manager Limitations and Restrictions

You cannot create and manage switch clusters through the device manager. To create and

manage switch clusters, use the CLI.

Device Manager Notes

These notes apply to the device manager:

We recommend that you use this browser setting to display the device manager from

Microsoft Internet Explorer in the least amount of time.

From Microsoft Internet Explorer:

1. Choose Tools > Internet Options.

2. Click Settings in the “Temporary Internet files” area.

3. From the Settings window, choose Automatically.

4. Click OK.

5. Click OK to exit the Internet Options window.

The HTTP server interface must be enabled to display the device manager. By default,

the HTTP server is enabled on the switch. Use the show running-config privileged

EXEC command to see if the HTTP server is enabled or disabled.
