Configuring 802.1q tag-type translation
11
•
Since the uplink (to the provider cloud) and the edge link (to the customer port) must have
different 802.1q tag-types, make sure the uplink and edge link are in different port regions.
•
If you configure a port with an 802.1q tag-type, the device automatically applies the 802.1q
tag-type to all ports within the same port region.
•
If you remove the 802.1q tag-type from a port, the device automatically removes the 802.1q
tag-type from all ports within the same port region.
•
Brocade does not recommend configuring different 802.1q tag-types on ports that are part of
a multi-slot trunk. Use the same 802.1q tag-type for all ports in a multi-slot trunk.
•
Multiple 802.1Q tag types can be assigned to an interface module. Depending on the module,
an 802.1Q tag can be assigned to an individual port or to a group of ports.
Table 63 describes
the granularity at which each of the device interface modules can have 802.1Q tag-types
assigned.
Enabling 802.1q tag-type translation
To enable 802.1q tag-type translation, configure an 802.1q tag-type on the provider core link,
between the provider core switches (refer to
Figure 28 ). Enter commands such as the following.
BigIron RX (config)# tag-type 9100 e 11 to 12
BigIron RX (config)# aggregated-vlan
Note that since ports 11 and 12 belong to the port region 9 – 16, the 802.1q tag-type actually
applies to ports 9 – 16.
NOTE
Do not configure 802.1q tag-type translation on the edge link (to the customer edge switch).
Syntax: [no] tag-type <num> [ethernet <slot-number>/<port-number> [to
<slot-number>/<port-number> ]]
The <num> parameter specifies the tag-type number and can be a hexadecimal value from 0 - ffff.
The default is 8100. Note that you must specify a value other than 8100.
The <slot-number>/<port-number> [to <slot-number>/<port-number> ] parameter specifies the
ports that will use the defined 802.1q tag-type. This parameter operates with the following rules:
•
If you specify a single port number, the 802.1q tag-type applies to all ports within the port
region. For example, if you enter the command tag-type 9100 e 1, the device automatically
applies the 802.1q tag to ports 1 – 8 since all of these ports are in the same port region
(controlled by the same DMA). Use the show running-config command at any level of the CLI to
view port regions. Note that on Gigabit Ethernet modules, ports 1 and 2 belong to the same
port region.
•
If the port that you specify is part of a multi-slot trunk, the device automatically applies the
802.1q tag-type to all of the ports that are part of the multi-slot trunk.
