VLAN Stacking Example

23.2 VLAN Stacking Port Roles

Each port can have three VLAN stacking “roles”, Normal, Access Port and Tunnel Port (the latter
is for Gigabit ports only).

• Select Normal for “regular” (non-VLAN stacking) IEEE 802.1Q frame switching.
• Select Access Port for ingress ports on the service provider's edge devices (1 and 2 in the VLAN

stacking example figure). The incoming frame is treated as "untagged", so a second VLAN tag
(outer VLAN tag) can be added.

Note: Static VLAN Tx Tagging MUST be disabled on a port where you choose Normal or

Access Port.

• Select Tunnel Port (available for Gigabit ports only) for egress ports at the edge of the service

provider's network. All VLANs belonging to a customer can be aggregated into a single service
provider's VLAN (using the outer VLAN tag defined by the Service Provider’s (SP) VLAN ID
(VID)).

Note: Static VLAN Tx Tagging MUST be enabled on a port where you choose Tunnel

Port.
