platform vlan-stacking-tpid
Overview
This command specifies the Tag Protocol Identifier (TPID) value that applies to all
frames that are carrying double tagged VLANs. All nested VLANs must use the
same TPID value. (This feature is sometimes referred to as VLAN stacking or VLAN
double-tagging.)
Use the
no
variant of this command to revert to the default TPID value (0x8100).
NOTE
:
Because the additional tag increases the frame size beyond 1522 bytes, you must
increase the MRU size to activate VLAN-stacking. Go into interface mode for the
appropriate ports and use the
mru
command.
