Re: HSRP Problems

chrismorris · ‎02-10-2004

I have two Cisco 4503 switches with Sup IIIs running 12.1(20) enhanced. They are dual connected to each other. A show standby shows the correct information i.e. that one is active and one is standby. However when I power off the active router the standby does not assume the virtual address and does not make itself active. Anyone had similar problems?

Not really, but you did provide not too much info.

Could we have some configs?

What is the output of "sh stand" before and after the primary system is switched off?

In the output of sh stand, there is a line that states when the last hsrp-packet was seen and I am curious what it says.

Regards,

Leo

I have attached the 2 configs. Also below is the output of a show standby on the 2 switches. Difficult for me to obtain the output when one is powered off as they are in a live environment.

Sh standby on switch1

MACRCORE01#sh standby

Vlan1 - Group 1

Local state is Active, priority 150, may preempt

Hellotime 3 sec, holdtime 10 sec

Next hello sent in 2.206

Virtual IP address is 180.90.1.1 configured

Active router is local

Standby router is 180.90.1.254 expires in 7.088

Virtual mac address is 0000.0c07.ac01

2 state changes, last state change 17:12:30

IP redundancy name is "hsrp-Vl1-1" (default)

Sh standby on Switch 2

MACRCORE02#sh standby

Vlan1 - Group 1

Local state is Standby, priority 110

Hellotime 3 sec, holdtime 10 sec

Next hello sent in 2.462

Virtual IP address is 180.90.1.1 configured

Active router is 180.90.1.253, priority 150 expires in 8.892

Standby router is local

15 state changes, last state change 17:09:22

IP redundancy name is "hsrp-Vl1-1" (default)

Hello,

It is a pity that you could not upload the output of: sh stand when it is not working.

I meant these two lines:

Active router is 180.90.1.253, priority 150 expires in 8.892 << THIS TIMEOUT SHOULD BE CHECKED

Standby router is local

The active router should expire after about 10s.

Your hsrp-config looks OK.

One more thing to try is to put all links in the port-channel on the same board. Now you have 1/1 and 3/1 as members. Besides, the following URL might be of help:

Try adding these lines to each router under VLAN1:

standby 1 timers 5 10

standby 1 preempt

This will probably make things fail over more smoothly..
