Important Notes 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. (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) 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. • 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) Hardware Limitations and Restrictions 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.

Then enter the auto qos voip cisco-phone command on each of these interfaces to reapply the configuration.
