Hi Commnity,
We have two cisco 6500 swtiches. Switch A is a active state of HSRP and Switch B in stanby state, After 2 days we are going have go-live test for Switches failove redudancy.
Please see the sample HSRP confiuration for both switches
SWTICH A
interface Vlan 100
description << RECEPTION>>
ip address 10.1.2.254 255.255.255.0
ip route-cache flow
standby delay minimum 20 reload 25
standby 3 ip 10.1.2.1
standby 3 priority 110
standby 3 preempt delay minimum 380
SWITCH B
interface Vlan3
description << RECEPTION>>
ip address 10.1.2.253 255.255.255.0
ip route-cache flow
standby delay minimum 20 reload 25
standby 3 ip 10.1.2.1
standby 3 priority 95
standby 3 preempt delay minimum 380
SWITCH A# sh stanby brief
Interface Grp Prio P State Active addr Standby addr Group addr
Vl3 3 110 P Active local 10.1.2.253 10.1.2.1
SWITCH B #
Interface Grp Prio P State Active addr Standby addr Group addr
Vl3 3 95 P Standby local local 10.1.2.1
If there is any misconfiguration, your sugesstion will be highly appreciated.

I think it's also recommended that trunks be set to desirable on one switch, the other to auto

In your very first post I don't understand this config , you have the same address space in 2 different vlans . They should be in the same L3 vlan on both sides. You have one side as vlan 100 and the other as vlan 3 . I would verify you have not done this on other vlans too ...

Hi glen,
Actually it was wrongly posted, currently we are working here vlan 2 and vlan 19.

Hi Mike and Jon,
Here my scope was to test the two 6500 failover.
Finally I shutdown my core 1 and core 2 became active within 15 seconds. Everthing was working fine. No vlans got any issue.
I was really amazed.

Dear Samir ,
Why don't you create ether channel between switches...instead of trunk link .
SWTICH A config :
interface Vlan 100
description << RECEPTION>>
ip address 10.1.2.254 255.255.255.0
ip route-cache flow
standby 3 ip 10.1.2.1
standby 3 priority 110
standby 3 preempt
interface Port-channel5
description ****Ether channel between 6500 *****
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
Interface gig 2/23
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 5 mode on
SWITCH B
interface Vlan3
description << RECEPTION>>
ip address 10.1.2.253 255.255.255.0
ip route-cache flow
standby 3 ip 10.1.2.1
standby 3 preempt
interface Port-channel5
description ****Ether channel between 6500 *****
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
Interface gig 2/23
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 5 mode on
Note : You can place one more port on ether channel so that you would have redundancy for ether channel link.
HSRP messages will be listened through ether channel and whenever you shut down vlan on switch A , vlan will be active on switch B immediatly.
