5.9 S-VID Translation Table
The S-VID Translation Table object is used to configure the VID Translation Table, which
maintains a bi-directional mapping between a Local S-VID (used in data and protocol frames
transmitted and received through a CNP or PNP) and a Relay S-VID (used by the filtering and
forwarding process).
Each VID Translation Table definition contains Component, Port, Local S-VID values and the
Relay S-VID values for each specified S-VID. If no entry exists in this table for a specified
Component, Port and Local S-VID, then a substitute value will be used by looking at the
Relay S-VID that is specified in a frame received on a Local S-VID Port.
All S-VID Translation Table entries are permanent and will be restored when the device is
reset.
5.9.1 S-VID Translation Table Commands
5.9.1.1 Set
C
reate and modify S-VID Translation Table entries using the Set command:
set svid-xlat s1 <ext-bridge-port-list> <vid> relay-svid <vid>
If the S-VID Translation Table entry does not already exist, the Set command creates it and
assigns the attributes specified. Upon creation, in the event that an attribute is not explicitly
specified, the entry is created with the default value for that attribute.
If the S-VID Translation Table entry already exists, then the Set command will replace the
attributes that are currently defined for the entry with those specified in the command.
Note the following conditions for execution:
• The Set command is valid only for bridge ports that are S-component ports.
• Creating a new S-VID Translation Table entry fails if the port specified belongs
to a C-component and not a S-component.
• The Set command operation also fails if the S-VID specified is not yet defined in
the VLAN Table.
