Example : How Trunk Area assignment affect 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.
When you assign an area within a trunk group, that group is F_Port masterless trunking enabled.
The TA that you assign must be within the 8-port trunk group beginning with port 0 (zero). After you
assign a TA to a port, the port immediately acquires the TA as the area of its PID. Likewise, after you
remove a TA from a port, the port immediately acquires the default area as its PID. F_Port trunking
prevents reassignments of the Port ID also referred to as the Address Identifier. Table 90 shows an
example of an Address Identifier.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the portDisable command for each port to be included in the TA.
3. Enter the portTrunkArea --enable command to enable the Trunk Area for ports 36-39 with
index number 37.
switch:admin> porttrunkarea --enable 36-39 -index 37
Trunk index 37 enabled for ports 36, 37, 38 and 39.
When you assign a trunk area on a port, it enables trunking on the F_Ports automatically. 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.
4. Re-enable ports 36-39 by issuing portEnable for each port in the TA.
5. Enter the switchshow command to display the switch and port information.
6. Enter the porttrunkarea --show enabled
command to display the TA-enabled port
configuration.
switch:admin> porttrunkarea --show enabled
