Force failover of an HSRP active without interruption

[ManuelCasal1985]

If force the failover with hsrp, would it be an interruption on that subnet?.

If preempt is on

And you simply change the priority from lower to higher on the standby switch. There should be no traffic inturuption.

---switch 1----

interface Vlan10

standby 1 ip 10.129.10.1

standby 1 priority 101

standby 1 preempt

---switch 2----

interface Vlan10

standby 1 ip 10.129.10.1

standby 1 priority 110

standby 1 preempt

Switch 2 will be active.  Simply go on switch 1 and enter

interface Vlan10

standby 1 priority 120

It will be come active

Is their a command for failover via HSRP?

[mikegrous]

You have to enable preempt on both cores. 1 core will be hsrp active due to its higher priority. If you want the other core active simplly make that priority higher.
