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 802.1Q 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

These are the VLAN limitations:

• 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

These are the 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

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. (CSCsd17765)
