Switchport Vlan Mapping - Cisco Catalyst 4500 Series Command Reference Manual

switchport vlan mapping

switchport vlan mapping
Use the switchport vlan mapping interface configuration command to configure VLAN mapping on a trunk
port. You can configure one-to-one VLAN mapping, traditional IEEE 802.1Q tunneling (QinQ) mapping, or
selective QinQ mapping. Use the no form of the command to disable the configuration.
Syntax Description

Usage Guidelines
Before configuring VLAN mapping on an interface, enter the switchport mode trunk interface
configuration command to configure the interface as a trunk port.
You can configure VLAN mapping on a physical interface or on a port channel of multiple interfaces
with the same configuration.
To configure one-to-one VLAN mapping, use the switchport vlan mapping vlan-id translated-id
command.
To avoid mixing customer traffic, when you configure traditional QinQ on a trunk port,you should use
Note
the switchport trunk allowed vlan vlan-id interface configuration command to configure the outer
VLAN ID (S-VLAN) as an allowed VLAN on the trunk port.

Specifies the original (customer) VLAN or VLANs (C-VLANs), also
known as the VLAN on the wire, for one-to-one or selective QinQ
mapping. You can enter multiple VLAN IDs separated by a comma or a
series of VLAN IDs separated by a hyphen (for example 1,2,3-5). The
range is from 1 to 4094.
Specifies the translated VLAN-ID: the S-VLAN to be used in the service
provider network. The range is from 1 to 4094.
Adds a translated VLAN-ID to specify a VLAN tunnel (add an outer
S-VLAN tag). The range of the S-VLAN tag is 1 to 4094. Use these
keywords for traditional QinQ mapping.
In the no switchport vlan mapping command, specifies that all VLAN
mapping configurations on the interface are deleted.
