Standby ACE not switching to active even when priority of active member is decreased due to vlan interface tracking.

I have 2 ace in active standby setup with FT configured, FT is working fine when i shut down the active box,at that time my standby becomes active.

I have enabled vlan interface tracking recently, when i shut down the interface from switch to which ACE is connected, i can see the priority is decreased in active ace than stanby but still stanby doenot become active at that time.

FT config:

ft interface vlan 2

  ip address 10.10.10.1 255.255.255.0

  peer ip address 10.10.10.2 255.255.255.0

  no shutdown

ft peer 1

  heartbeat interval 100

  heartbeat count 10

  ft-interface vlan 2

  query-interface vlan 421

ft group 1

  peer 1

  priority 150

  peer priority 145

  associate-context Admin

  inservice

 

ft track interface AAA

  track-interface vlan 421

  peer track-interface vlan 421

priority 50

  peer priority 5

ft track interface BBB

  track-interface vlan 431

  peer track-interface vlan 431

priority 50

  peer priority 5

Any help would be appreciated.

Regards

Re: Standby ACE not switching to active even when priority of ac

Did you enable the "svclc autostate" command on your switch? It is required for vlan-tracking.

greetings.

Re: Standby ACE not switching to active even when priority of ac

The fact is the priority of active is getting decreased when i shut the vlan port from switch side.

It is that still i have to enable "svclc autostate" on switch.

Set the priority of the tracked interface to 50.

Re: Standby ACE not switching to active even when priority of ac

As per my configuration ft track interace AAA & ft track interface BBB , peer track interface should be (ft vlan)vlan 2 or vlan 431 / 421.(interface vlan)

Can some one pls clear my doubt...?

I guess it depends on what you want to do. But usually you track on both sides the same vlan, if you want to track this interface.

sorry  had not seen you already had the priority.

What is the status of 'show ft track det' on each ACE when you shut down the interface ?

Re: Standby ACE not switching to active even when priority of ac

The problem is that you disabled "preempt"

Peer Preempt : Disabled

This is required for the standby to take over.

Actually, it is possible that preemot was automatically disabled because the 2 devices are not in-synch

Running cfg sync enabled : Enabled

Running cfg  sync status : Peer in Cold State. Error on Standby device when applying  configuration file

Do a " show ft config-error" to detect the problem.

Gilles.
