    I was informed that spannning tree is enabled by default on the Aruba controllers.  I learned to disabeel the spanning tree setting on the interfaces to do the follwoing:

     

    (Aruba Controller) #local-configure enable<enter>

    (Aruba Controller)#configure terminal<enter>

    (Aruba Controller) (config) #interface gigabitethernet 0/0/3<enter>

    (Aruba Controller) ^(config-submode)#no spanning-tree<enter>

    (Aruba Controller) ^(config-submode)#write memory<enter>

    (Aruba Controller)>local-configure dsable<enter>

     

    Now my manager wants me to re-enble spanning tree for testing.  My question is now to re-enable spanning tree on an Aruba interface.

    Before I disabled spannit tree on port 0/0/3 the query reslts looked like the following:

     

    (Controller_Hostname) #show spanning-tree interface gigabitethernet 0/0/3<enter>

     

    The following shows if spanning tree is enabled:

    Interface GE 0/0/3 (port 4) in Spanning tree is DISCARDING

    Port path cost 20000, Port priority 128

    PortFast DISABLED P-to-P ENABLED

    BpduGuard DISABLED

    Designated root has priority 32768 address 20:4c:03:12:4b:d8

    Designated bridge has priority 32768 address 20:4c:03:12:4b:d8

    Designated port is 4, path cost 0

    Timers:  message age 0, forward delay 20, hold 0

    Counts:  BPDUs received 0, sent 0

    Same command sequence, but remove the 'no' before the spanning-tree:

     

    Aruba Controller) #local-configure enable<enter>

    (Aruba Controller)#configure terminal<enter>

    (Aruba Controller) (config) #interface gigabitethernet 0/0/3<enter>

    (Aruba Controller) ^(config-submode)#spanning-tree<enter>

    (Aruba Controller) ^(config-submode)#write memory<enter>

    (Aruba Controller)>local-configure disable<enter>
