| Description | This table contains the port based VLAN-to-VLAN
associations for the device's physical ports.
The translation is applied in both ingress and egress
sides of the layer 2 trunk on the port. It causes the
traffic arriving on the VLAN cvtPortOriginalVlan on
this port to be mapped to or tagged with the VLAN
cvtPortTranslatedVlan. It also causes all the traffic
internally tagged with the VLAN cvtPortTranslatedVlan
and leaving the port to be tagged with VLAN
cvtPortOriginalVlan.
A VLAN translation configuration that is applied to
Layer 2 ports that are not Layer 2 trunks is inactive.
The port based VLAN translations are mutually exclusive
to the global VLAN translations. The rows in this
table can only be created when the table
cvtGlobalTranslationTable is empty.
A conceptual row is created for a translation on a
particular physical port which supports the feature.
The value of the corresponding instance of
cvtPortTranslationMax determines the maximum number
of rows for the same port.
On some platforms, VLAN translation may be configured
per port group rather than per port. If multiple ports
belong to a port group, the VLAN translation configured
to any of the ports in such group will apply to all
ports in the same group. |
