Understanding VLAN Mapping

With software release 8.4(1) and later releases, VLAN mapping has been enhanced to allow you to map
any type of VLAN to any other type of VLAN without any VLAN range restrictions. VLAN mapping is
now configurable on a per-port or per-ASIC basis.
Before software release 8.4(1), VLAN mapping was configured globally. For detailed information, see

With VLAN mapping, you have the following options depending on the type of ASIC on the
switching module or supervisor engine (for the individual module ASIC specifics, see
VLAN mapping is not supported.
–
Per-port VLAN mapping is supported.
–
Per-ASIC VLAN mapping without the ability to enable or disable VLAN mapping on an
–
individual port basis is supported.
Per-ASIC VLAN mapping with the ability to enable or disable VLAN mapping on an individual
–
port basis is supported.
If a module does not support per-port VLAN mapping and supports only per-ASIC VLAN mapping,
VLAN mapping is applied to all the ports in the ASIC. If you change the mapping for any port in the
ASIC, the change is applied to all the ports in the ASIC.
Global VLAN mapping
The global VLAN mapping feature (see the
and the per-port/per-ASIC VLAN mapping features are mutually exclusive; only one feature can be
enabled at any time.
If global VLAN mapping is configured for any of the VLANs and you try to configure
per-port/per-ASIC VLAN mapping, the command is rejected and an error message is displayed.
Conversely, if per-port/per-ASIC VLAN mapping is configured for any of the VLANs and you try
to configure global VLAN mapping, the command is rejected and an error message is displayed.
