Brocade FastIron Ethernet Switch Platform and Layer 2 Switching Configuration Guide - Manual (Page 408)

• FastIron X Series devices support one configured tag-type per device along with the default tag-
type of 8100. For example, if you configure an 802.1Q tag of 9100 on ports 1 - 12, then later
configure an 802.1Q tag of 5100 on port 15, the device automatically applies the 5100 tag to all
ports in the same port region as port 15, and also changes the 802.1Q tag-type on ports 1 - 12 to
5100.
• 802.1ad tagging and VSRP are not supported together on the same device.
• In addition to tag-type , Brocade FCX Series devices support tag-profile . For more information,
refer to Configuring 802.1ad tag profiles on page 409 .
Enabling 802.1ad tagging
To enable 802.1ad tagging, configure an 802.1Q tag on the untagged edge links (the customer ports)
to any value other than the 802.1Q tag for incoming traffic. For example, in
Figure 90 on page 409,
the 802.1Q tag on the untagged edge links (ports 11 and 12) is 9100, whereas, the 802.1Q tag for
incoming traffic is 8100.
To configure 802.1 ad tagging as shown in Figure 90 on page 409, enter commands such as the
following on the untagged edge links of devices C and D.
device(config)# tag-type 9100 ethernet 11 to 12
device(config)# aggregated-vlan
Note that because 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 port [to port]]
The ethernet port to port 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 to all ports within the port region. For
example, if you enter the command tag-type 9100 ethernet 1 , the Brocade device automatically
applies the 802.1Q tag to ports 1 - 12 because all of these ports are in the same port region. 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.
Example 802.1ad configuration
The following figure shows an example 802.1ad configuration.
