Configuring 802.1Q-in-Q tagging

TurboIronE(config)#vlan 104 by port

TurboIronE(config-vlan-104)#tagged ethernet 6

TurboIronE(config-vlan-104)#untagged ethernet4

TurboIronE(config-vlan-104)#exit

TurboIronE(config)#vlan 105 by port

TurboIronE(config-vlan-105)#tagged ethernet 6

TurboIronE(config-vlan-105)#untagged ethernet 5

TurboIronE(config-vlan-105)#exit

TurboIronE(config)#write memory

Commands for device F

The commands for configuring device F are identical to the commands for configuring device E. In
this example, since the port numbers on each side of the configuration in

Figure 49

on page 402

are symmetrical, the configuration of device F is also identical to the configuration of device A and
device B.

TurboIronF(config)#vlan 101 by port

TurboIronF(config-vlan-101)#tagged ethernet 6

TurboIronF(config-vlan-101)#untagged ethernet 1

TurboIronF(config-vlan-101)#exit

TurboIronF(config)#vlan 102 by port

TurboIronF(config-vlan-102)#tagged ethernet 6

TurboIronF(config-vlan-102)#untagged ethernet 2

TurboIronF(config-vlan-102)#exit

TurboIronF(config)#vlan 103 by port

TurboIronF(config-vlan-103)#tagged ethernet 6

TurboIronF(config-vlan-103)#untagged ethernet 3

Configuring 802.1Q-in-Q tagging

802.1Q-in-Q tagging provides finer granularity for configuring 802.1Q tagging, enabling you to
configure 802.1Q tag-types on a group of ports. This feature allows you to create two identical
802.1Q tags (802.1Q-in-Q tagging) on a single device. This enhancement improves SAV
interoperability between devices and other vendors’ devices that support the 802.1Q tag-types, but
are not very flexible with the tag-types they accept.

NOTE

Devices treat a double-tagged Ethernet frame as a Layer 2 only frame. The packets are not
inspected for Layer 3 and Layer 4 information, and operations are not performed on the packet
utilizing Layer 3 or Layer 4 information.

Figure 50

shows an example application with 802.1Q-in-Q tagging.
