I am setting up a production switch before I actually plug it in. I am configuring spanning tree priorities for the switches. This switch is NOT my primary root or secondary root switch. The cmds I typed in so far are :
spanning-tree mode pvst
spanning-tree extend system-id
spanning-tree vlan 1,3-8,11-14,16,20,80-81,88,96,110,120,124,130 priority 57344
spanning-tree vlan 134,160,192,246-252,254-256,802 priority 57344
spanning-tree portfast default
But when I do a show spanning-tree, I get: No spanning tree instance exists.
Could it be because I have not plugged in any trunk ports yet (gotta wait for a maintenance window), or am I missing another cmd ? I usually like to see some results before plugging something into production network, but if this is all I get for now, that is fine, I just want to be sure.
Thanks in advance
