ACE failover not working

Answered Question
Mar 18th, 2010

Hi,

I am configuring failover on two ACE 4710 device using a dedicated interface (gig1/4) connected to a switch with same VLAN. Below are my ACE ft config:

ACE1:

--------

Admin context

interface gigabitEthernet 1/4
  ft-port vlan 30
  no shutdown

ft interface vlan 30
  ip address 9.9.9.1 255.255.255.0
  peer ip address 9.9.9.2 255.255.255.0
  no shutdown

ft peer 1
  heartbeat interval 300
  heartbeat count 20
  ft-interface vlan 30
ft group 1
  peer 1
  priority 200
  associate-context test
  inservice

test context

-----------------

ft track interface track_vlan14
  track-interface vlan 14
  peer track-interface vlan 14
  priority 200
  peer priority 100

ACE2:

---------

Admin context

interface gigabitEthernet 1/4
  ft-port vlan 30
  no shutdown


ft interface vlan 30
  ip address 9.9.9.2 255.255.255.0
  peer ip address 9.9.9.1 255.255.255.0
  no shutdown

ft peer 1
  heartbeat interval 300
  heartbeat count 20
  ft-interface vlan 30
ft group 1
  peer 1
  peer priority 200
  associate-context test
  inservice

test context

-----------------

ft track interface track_vlan14
  track-interface vlan 14
  peer track-interface vlan 14
  priority 100
  peer priority 200

Below is the ft peer result:

LB# sh ft peer summary

Peer Id                      : 1
State                        : FSM_PEER_STATE_DOWN
Maintenance mode             : MAINT_MODE_OFF
FT Vlan                      : 30
FT Vlan IF State             : UP
My IP Addr                   : 9.9.9.1
Peer IP Addr                 : 9.9.9.2
Query Vlan                   : Not Configured
Query Vlan IF State          : DOWN
Peer Query IP Addr           : 0.0.0.0
Heartbeat Interval           : 300
Heartbeat Count              : 20
SRG Compatibility            : INIT
License Compatibility        : INIT
FT Groups                    : 1

ACE are configured in one arm mode. The problem is ft IP is not reachable from any of the ACE. I am getting arp request on the switch but not on ACE devices. Not sure what's the problem.

Thanks,

Pawan

I have this problem too.

Hi,

verify that your interface on your switch is configured as trunk?

I had a similar problem where FT was correctly configured but no traffic was being passed.

Changing the switchport on the switch to trunk solved my problem, nevertheless the port on, the ACEs were not configured as trunks.

It seems that it trunks by default.

HTH,

Dario

Could anybody suggest any solution? I have it's not the problem with the switch connectivity as I can ping the interface if I use them for data traffic.

Thanks,

Pawan

Thanks Dario. After making switch interface as trunk port, it started working.
