802.1ad tagging configuration
Configuration rules for 802.1ad tagging
• Because the uplink (to the provider cloud) and the edge link (to the customer port) must have
different 802.1Q tags, make sure the uplink and edge link are in different port regions. Refer to
“About port regions” on page 556 for a list of valid port regions.
• On devices that support port regions, if you configure a port with an 802.1Q tag-type, the
Brocade device automatically applies the 802.1Q tag-type to all ports within the same port
region. Likewise, if you remove the 802.1Q tag-type from a port, the Brocade device
automatically removes the 802.1Q tag-type from all ports within the same port region.
• Q-in-Q and SAV are not supported on the following :
- 48-port 10/100/1000 Mbps (RJ45) Ethernet POE interface module (SX-FI48GPP)
- 2-port 10-Gigabit Ethernet interface module (SX-FI-2XG)
- 8-port 10-Gigabit Ethernet interface module (SX-FI-8XG)
- 24-port Gigabit Ethernet fiber interface module (SX-FI-24HF)
- 24-port Gigabit Ethernet copper interface module with PoE+ (SX-FI-24GPP)
• 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, FastIron WS and Brocade FCX Series devices support tag-profile. For
more information, refer to “Configuring 802.1ad tag profiles” on page 808.
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 89, 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 89, enter commands such as the following on the
untagged edge links of devices C and D.
Brocade(config)# tag-type 9100 ethernet 11 to 12
Brocade(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>]]
Specify the port variable in one of the following formats:
• FWS, FCX, and ICX stackable switches – stack-unit/slotnum/portnum
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• ICX devices – slotnum/portnum
• FESX compact switches – portnum
