4| Ethernet Bridge and VLANs
Listing unknown VLAN membership
To display information on the unknown VLAN membership of the bridge ports, execute following command:
Removing a port from the unknown VLAN
To remove a bridge port from the unknown VLAN, use the command
:eth bridge unknownvlan ifdelete
.
Only one parameter must be specified:
Intf : the name of the bridge port.
Optionally, the bridge instance can be specified:
Brname : the name of the bridge instance. If the parameter is not specified, the default bridge instance is
used.
Modifying unknown VLAN membership
To modify the configuration of a bridge port that is already member of the unknown VLAN, execute the
command
:eth bridge unknownvlan ifconfig
.
Only one parameter must be specified:
Intf : the name of the bridge port.
Optionally, other parameters can be specified:
Brname : the name of the bridge instance. If the parameter is not specified, the default bridge instance is
used.
Some hardware limitations exist in case of Thomson Gateway devices with an Ethernet switch. The
unknown VID policy feature works fine in following cases:
No switch ports are a member of the unknown VLAN.
All switch ports are a member of the unknown VLAN.
Other scenarios can not be handled due to hardware restrictions.
