Access Gateway N_Port trunking

Configuration management for trunk areas
Ports from different ADs are not allowed to join the same Trunk Area group. The porttrunkarea
command prevents the different AD's from joining the 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 3,7in 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.
Enabling Access Gateway trunking
1. Disable ports 36 - 39 by executing portdisable port for each port to be included in the TA.
2. Enable Trunk Area for ports 36 - 39 with area number 37:
switch:admin> porttrunkarea --enable 36-39 -index 37
Trunk area 37 enabled for ports 36, 37, 38 and 39.
3. Re-enable ports 36-39 by executing portenable port for each port in the TA.
4. Show switch/port information:
switch:admin> switchshow
switchName: SPIRIT_B4_01
switchType: 66.1
switchState: Online
switchMode: Native
switchRole: Principal
switchDomain: 2
switchId: fffc02
switchWwn: 10:00:00:05:1e:41:22:80
zoning: OFF
switchBeacon: OFF
