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 24 on page 302
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 enables you to configure 802.1Q tag-types on a group of ports, such as trunk
ports, thereby enabling the creation of two identical 802.1Q tags (802.1Q-in-Q tagging) on a single
device. This feature improves SAV interoperability between Brocade devices and other vendors’
devices that support the 802.1Q tag-types, but are not very flexible with the tag-types they accept.
Figure 25 on page 307 shows an 802.1Q configuration example.
