configure dot1q tagmapping ports

configure dot1q tagmapping <input_vlanid/output_vlanid> ports <portlist>
{egress {priority <priority>} | ingress {priority <priority>}}
Description
Configures the VLAN tag mapping attributes for a PoS or ATM port.

Default
The default is to initialize the tables so the VLAN IDs are not altered by the mapping operations (for
example, an input VLAN ID of n is always mapped to an output VLAN ID of n), and the frame priority
is preserved.
Usage Guidelines
This command is only applicable when BCP is enabled on the port. Currently, the command is only
supported for PoS ports. Two mapping tables are supported per PoS port. One of the tables is used in
the egress direction and the other table is used in the ingress direction. Each of the tables enable an
input VLAN ID to be mapped to an output VLAN ID, which can be useful in reconciling policy
differences at customer/service provider boundaries. The
