3 Trunking in Access Gateway mode 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. Example : How Trunk Area assignment affects the port Domain,Index 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. Assigning a Trunk Area You must enable trunking on all ports to be included in a Trunk Area before you can create a Trunk Area. Use the portCfgTrunkPort or switchCfgTrunk command to enable trunking on a port or on all ports of a switch. Issue the porttrunkarea command to assign a static TA on a port or port trunk group, to remove a TA from a port or group of ports in a trunk, and to display masterless trunking information. You can remove specified ports from a TA using the porttrunkarea --disable command; however this command does not unassign a TA if its previously assigned Area_ID is the same address identifier (Area_ID) of the TA unless all the ports in the trunk group are specified to be unassigned. For more information on the porttrunkarea command, enter help porttrunkarea or see the Fabric OS Command Reference. F_Port trunking will not support shared area ports 16-47 on the Brocade FC8-48 blades. The following table shows an example of the Address Identifier. TABLE 7 Address identifier 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 76 5 4 3 2 10 Domain ID Area_ID Address Identifier Port ID 1. Connect to the switch and log in using an account assigned to the admin role. 2. Disable the ports to be included in the TA. 3. Enable TA for the appropriate ports. In the following example, TA is enabled for ports 13 and 14 on slot 10 with port index of 125. switch:admin> porttrunkarea --enable 10/13-14 -index 125 Trunk index 125 enabled for ports 10/13 and 10/14 4. Show the TA port configuration (ports still disabled). switch:admin> porttrunkarea --show enabled 52 Access Gateway Administrator's Guide 53-1001760-01
