8.6.3 S-VID Translation
The S-VID Translation table is used to maintain 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 is taken from 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 are restored when the device is
reset.
Use the following command to create and modify S-VID Translation table entries:
set svid-xlat s1 <ext-bridge-port-list> <vid> relay-svid <vid>
If the entry does not already exist, the set svid-xlat 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 entry already exists, then the set svid-xlat command replaces the attributes
that are currently defined for the entry with those specified in the comman d.
Note the following conditions for execution of the set svid-xlat command:
The command is valid only for bridge ports that are S-component ports.
The set svid-xlat command fails if the port specified belongs to a C-
component and not an S-component.
The set svid-xlat command also fails if the S-VID specified is not yet
defined in the VLAN table.
Use the following command to delete S-VID Translation table entries and clear their
associated statistics:
clear svid-xlat {s1 | all} {<ext-bridge-port-list> | all} {<vid-
list> | all}
Use the following command to display S-VID Translation table entries:
show svid-xlat [{s1 | all}
[{<ext-bridge-port-list> | all}
[{<vid-list> | all}
[info]]]]
8.6.4 Forwarding Data Base (FDB)
The Forwarding Data Base (FDB) enables access to general parameters of the FDB
Address table, which specifies configuration and control information for each Filtering
Database currently operating on the device.
