21 vlans 4 0 0 127 131
This is the some of the output of
show spanning-tree summary total.
What does this indicates?
We have in all 21 VLAN configured on this switch. Are these numbers too drastic as I have no idea about what these numbers indicate. ( Forwarding and STP active )
Please share the experience.
Any link on cisco.com is highly appreciable.
Thanks in advance.

Following output specifies in your switch 21 vlans are configured out of which 127 ports are in forwarding state,4 are in blocking state and on 131 ports stp is active.

I think this output belongs to the ROOT BRIDGE.
Check which vlans are in the blocking state by:
#show spanning-tree summary
May be some on your Vlans are in " *PVID_Inc " check by giving the following commands:
#sh spanning-tree vlan 1 (check those vlans which are in blocking state)
&
#sh spanning-tree inconsistentports
Can you post with the outputs?
