How to find out Secondary STP Root bridge in cisco switche network

[ahmad82pkn]

Hi, i need to find out Root Primary and Root Secondary bridge in all my offices.

sh spanning-tree summary command can tell me which switch is root bridge primary, but how can i find secondary root easily with some simple command?

sh spanning-tree summary
Switch is in pvst mode
Root bridge for: VLAN0001-VLAN0002, VLAN0005, VLAN0008, VLAN0031

I'm not sure if there is a simple way of finding the bridge with the SECOND best priority.
