Configuration Management For Trunk Areas - HP StoreFabric SN6500B Administrator's Manual

Trunk group creation
Port trunking is enabled between two separate Fabric OS switches that support trunking and where
all the ports on each switch reside in the same quad and are running the same speed. Trunk
groups form when you connect two or more cables on one Fabric OS switch to another Fabric OS
switch with ports in the same port group or quad. A port group or a quad is a set of sequential
ports; for example, ports 0-3. The Brocade 300 switch supports a trunk group with up to eight
ports. The trunking groups are based on the user port number, with eight contiguous ports as one
group, such as 0-7, 8-15, 16-23 and up to the number of ports on the switch.
Setting up trunking
Use the following steps to set up trunking.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Ensure that both modules (Edge switch and the switch running in AG mode) have the trunking
3. Ensure that the ports have trunking enabled by issuing the portcfgshow command. If trunking
4. Ensure that the ports within a trunk have the same speed.
5. Ensure that the ports within an ASIC trunk group are used to group the ports as part of a trunk
6. Ensure that both modules are running the same Fabric OS versions.

Configuration management for trunk areas

The porttrunkarea command does not allow ports from different admin domains (ADs) and ports
from different logical switches to join the same trunk area (TA) group.
When you assign a TA, the ports within the TA group will have the same Index. The Index that was
assigned to the ports is no longer part of the switch. Any Domain,Index (D,I) AD that was assumed
to be part of the domain may no longer exist for that domain because it was removed from the
switch.
Trunk area assignment example
If you have AD1: 3,7; 3,8; 4,13; 4,14 and AD2: 3,9; 3,10, and then create a TA with Index 8 with
ports that have index 7, 8, 9, and 10. Then index 7, 9, and 10 are no longer with domain 3. This
means that AD2 does not have access to any ports because index 9 and 10 no longer exist on
domain 3. This also means that AD1 no longer has 3,7 in effect because Index 7 no longer exists
for domain 3. AD1's 3,8, which is the TA group, can still be seen by AD1 along with 4,13 and 4,14.
A port within a TA can be removed, but this adds the Index back to the switch. For example, the
same AD1 and AD2 with TA 8 holds true. If you remove port 7 from the TA, it adds Index 7 back to
the switch. That means AD1's 3,7 can be seen by AD1 along with 3,8; 4,13 and 4,14.
