23.6 VLAN Stacking Commands
Use these commands to add an outer VLAN tag to the inner IEEE 802.1Q tagged frames that enter
your network.
23.7 VLAN Stacking Command Examples
In the following example figure, both A and B are Service Provider’s Network (SPN) customers with
VPN tunnels between their head offices and branch offices respectively. Both have an identical VLAN
tag for their VLAN group. The service provider can separate these two VLANs within its network by
adding tag 37 to distinguish customer A and tag 48 to distinguish customer B at edge device x and
then stripping those tags at edge device y as the data frames leave the network.
Table 85 VLAN Stacking Commands
COMMAND DESCRIPTION
interface port-channel <aid>
Enters config-interface mode for the specified port(s).
aid: <xe|ge|pon>-<slot>-<port>
vlan-stacking priority <0-7>
Sets the priority of the specified port(s) in port-based VLAN
stacking.
vlan-stacking role
<normal|access|tunnel>
Sets the VLAN stacking port roles of the specified port(s).
normal: The OLT ignores frames received (or transmitted) on this
port with VLAN stacking tags.
access: the OLT adds the SP TPID tag to all incoming frames
received on this port.
tunnel: (available for Gigabit and faster ports only) for egress
ports at the edge of the service provider's network.
Note: In order to support VLAN stacking on a port, the port must
be able to allow frames of 1526 Bytes (1522 Bytes + 4
Bytes for the second tag) to pass through it.
