tagpvid disable|enable
Disables or enables VLAN tag persistence. When disabled, the VLAN tag is removed from pack-
ets whose VLAN tag matches the port PVID. The default value is disabled for INT and EXT
ports, and enabled for MGT ports.
fastfwd disable|enable
Disables or enables Port Fast Forwarding, which permits a port that participates in Spanning
Tree to bypass the Listening and Learning states and enter directly into the Forwarding state.
While in the Forwarding state, the port listens to the BPDUs to learn if there is a loop and, if
dictated by normal STG behavior (following priorities, etc.), the port transitions into the Blocking
state. This feature permits the GbESM to interoperate well within Rapid Spanning Tree networks.
ena
Enables the port.
dis
Disables the port. (To temporarily disable a port without changing its configuration attributes, refer
to “Temporarily Disabling a Port” on page 211.)
cur
Displays current port parameters.
