4828965: Disabling global GVRP state prevents dynamic VLANs from leaving ports

If you disable GVRP globally on the switch by issuing the following command:

Console(config)#no bridge-ext gvrp

then VLANs that have been learned dynamically are not dropped even after the GVRP leave-all timer has expired (normally 10 seconds). These VLANS remain active on the ports that learned them, and you must remove them manually. The following sample command removes the dynamically learned VLAN called vlan 3 from NETP4:

Console#show vlan

Error messages are incomplete.

The web GUI (Monitoring=>Port Statistics=>NETMGT) cannot provide traffic statistics for the NETMGT port. The data for the NETMGT port appears as zeroes instead of valid data. There is currently no workaround for this problem.

Adding packet filtering rules from the Management Port=>Packet Filtering page must be performed with care, because blank fields on the page will default to a value of zero. Make sure that you have entered a value into every field you require, and check that the rule displayed when you click Add is the rule that you require. In particular, the Protocol Number box next to the Protocol Name box will accept a protocol name (instead of a numerical value) without displaying an error, and if you type a name instead of a numerical value the field defaults to zero.
