VLAN Stacking Example
12.5.3 VLAN Stacking Port Roles
Each port can have three VLAN stacking “roles”, Normal, Access Port and
Tunnel (the latter is for Gigabit ports only).
Note: Some devices do not support all roles.
• 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 SP VID).
Note: Static VLAN
Tx Tagging
MUST be enabled on a port where you choose
Tunnel
Port
.
