Cisco Cisco Gigabit Ethernet Switch Module (CGESM) for HP Release Notes

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. (CSCeb31087)

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. (CSCse06827)

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

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. (CSCef45718)

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. (CSCsd17765)

These sections describe the important notes related to this software release:

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 12.2(40)SE (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

If this happens, enter the no auto qos voip cisco-phone interface command on all interface with this 
configuration to delete it. Then enter the auto qos voip cisco-phone command on each of these 
interfaces to reapply the configuration.
