Function: Configure the forbidden vlan for a port. Note that this command can only be
used to configure on trunk or hybrid ports and the port with GVRP not enabled. No
command cancels the forbidden vlanlist for a port.
Parameters: WORD, add the vlanList as forbidden vlan and cover the previous
configuration
all, set all VLANs as forbidden vlan
add WORD, add vlanList to the current forbidden vlanList
except WORD, set all VLANs as forbidden vlan except vlanList
remove WORD, remove vlan specified by vlanList from current forbidden
vlanList
Command Mode: Port mode
Default: Forbidden vlanList is empty
Usage Guide: Tag the corresponding position for forbidden vlanList and clear allow
vlanList flags in ports. A port leaves these VLANs if it joins them statically, and it sends
message to GVRP module to enable corresponding registered machine of the port to
enter forbidden mode.
Example: Port quits the corresponding VLAN and the corresponding registered machine
of GVRP to enter forbidden mode.
