Enabling 802.1Q-in-Q tagging

To enable the 802.1Q-in-Q feature, configure an 802.1Q tag type on the untagged edge links (the
customer ports) to any value other than the 802.1Q tag for incoming traffic.
For example, in
whereas, the 802.1Q tag for incoming traffic is 8100.
To configure 802.1 Q-in-Q tagging as shown in
the untagged edge links of devices C and D.
BigIron RX(config)# tag-type 9100 e3/1 to 3/2
BigIron RX(config)# aggregated-vlan
Note that since ports 11 and 12 belong to the port region 1 – 12, the 802.1Q tag actually applies
to ports 1 – 12.
Syntax: [no] tag-type <num> [ethernet <slot-number>/<port-number> [to
The <num> parameter specifies the tag-type number and can be a hexadecimal value from 0 - ffff.
The default is 8100.
The ethernet <port number> to <port number> parameter specifies the ports that will use the
defined 802.1Q tag. This parameter operates with the following rules:

If you specify a single port number, the 802.1Q tag applies only to that port. You can use the
show running-config command to view how the command has been applied.
If you do not specify a port or range of ports, the 802.1Q tag applies to all Ethernet ports on the
device.
