    Hello.  When trunks are created the spanning-tree priority for them is lowered so that they are preferred over single links of the same speed (and path-cost) downstream.  There is no effect when spanning-tree is disabled.

    8 is the default priority.  If you don't plan on enabling spanning-tree and really do not want to see it displayed in "show run" you could set the priority manually.  If it were me I'd leave it alone.  

     

    HP-Stack-2920(config)# show run interface trk1

    Running configuration:

    interface Trk1
    untagged vlan 1
    spanning-tree priority 4
    exit

    HP-Stack-2920(config)# span trk1 priority 8

    HP-Stack-2920(config)# show run interface trk1

    Running configuration:

    interface Trk1
    untagged vlan 1
    exit
