myself Mangesh I am facing problem with switching, I am feeling there is possible STP loop occuring somewhere in my network.

sh standby on core 3 6506:

Vlan20 - Group 1

Local state is Active, priority 200, may preempt

Hellotime 3 sec, holdtime 10 sec

Next hello sent in 1.764

Virtual IP address is 172.16.20.1 configured

Active router is local

Standby router is 172.16.254.252 expires in 7.628

Virtual mac address is 0000.0c07.ac01

12 state changes, last state change 14:09:03

IP redundancy name is "hsrp-Vl20-1" (default)

sh stndby on core1 6509:

Vlan20 - Group 1

Local state is Listen, priority 100, may preempt

Hellotime 3 sec, holdtime 10 sec

Virtual IP address is 172.16.20.1 configured

Active router is 172.16.20.252, priority 200 expires in 9.556

Standby router is 172.16.254.252 expires in 7.076

4 state changes, last state change 14:25:09

IP redundancy name is "hsrp-Vl20-1" (default)
