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.

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.
