Listing the VID translation table
To display all entries of the VID translation table, execute following command:
Configuring a VID translation entry
An entry of the VID translation table can be modified using the command
:eth bridge xtratag config
.
The entry is identified by the bridge port and the inner VID. The configured outer VID of this entry can be
modified. As a result, three parameters must be specified:
Intf : the name of the bridge port.
Innervid : the inner VID.
Outervid : the new outer VID. This parameter can be set to:
A number within the range from 1 through 4094.
Notag , indicating that no outer VLAN tag is added.
Transparent , indicating that the outer VID is set to the inner VID.
In addition, if the bridge port is not a member of the default bridge instance, following parameter must be
specified:
Brname : the name of the bridge instance to which the bridge port belongs. If this parameter is not
specified, the default bridge instance is selected.
Deleting a VID translation entry
To delete an entry of the VID translation table, execute the command
:eth bridge xtratag delete
.
Two parameters must be specified to define the entry to be deleted:
Intf : the name of the bridge port.
Innervid : the inner VID.
In addition, if the bridge port is not a member of the default bridge instance, the following parameter must be
specified:
