ACE4710 - Install New FT Peer

Hello Everyone

This is my first post on the Support Community, so please allow me some room for not following etiquette. I have recently taken delivery of a replacement 4710 as one half of a pair. The unit that has been replaced was the primary in the pair. The current active 4710 was the secondary in the pair. I am looking for an installation guide that specifically deals with reconnecting peers, with reference to:

1) OS differences

2) Config sync

3) Failover timings

The working 4710 is on:- c4710ace-t1k9-mz.A4_1_1.bin

Replacement:- c4710ace-mz.A4_2_0.bin

Working

FT Group                     : 1

Configured Status            : in-service

Maintenance mode             : MAINT_MODE_OFF

My State                     : FSM_FT_STATE_ACTIVE

My Config Priority           : 50

My Net Priority              : 50

My Preempt                   : Disabled

Peer State                   : FSM_FT_STATE_UNKNOWN

Peer Config Priority         : Unknown

Peer Net Priority            : Unknown

Peer Preempt                 : Unknown

Peer Id                      : 1

No. of Contexts              : 1

ft interface vlan 1111
  ip address 192.168.254.2 255.255.255.252
  peer ip address 192.168.254.1 255.255.255.252
  no shutdown

ft peer 1
  heartbeat interval 300
  heartbeat count 10
  ft-interface vlan 1111
ft group 1
  peer 1
  no preempt
  priority 50
  peer priority 99
  associate-context Admin
  inservice

My concern is the mismatch in OS, yet the USB ports seem to be unsupported. I could configure the replacement with a lower priority, but would like to find some information on if this OS mismatch will cause issues and how best to copy from one device to another.

And yes, as you can probably gather, these devices are not my strongpoint, they were a legacy left by someone else with no documentation or explanations.

Thanks for your time

ACE4710 - Install New FT Peer

A penny dropped in the back of my mind, I brought up the management interface and set up a TFTP server locally, so, I have coped the image across. From here, I am going to reapply the config but lower the FT priority so that failover does not take place

Fingers crossed.

Re: ACE4710 - Install New FT Peer

put the same OS.

Then just configure basic connectivity, basic HA parameter and ft group for admin context only. Everything else will be synchronized.

usually I use the following file by copy/paste and I plug the box. Notice the "no preempt" in the ft group.

interface gigabitEthernet 1/1

  channel-group 1

  no shutdown

interface gigabitEthernet 1/2

  channel-group 1

  no shutdown

interface gigabitEthernet 1/3

  channel-group 1

  no shutdown

interface gigabitEthernet 1/4

  channel-group 1

  no shutdown

interface port-channel 1

  ft-port vlan 98

  port-channel load-balance src-dst-port

  no shutdown

ft interface vlan 98

  ip address 10.123.98.251 255.255.255.0

  peer ip address 10.123.98.250 255.255.255.0

  no shutdown

exit

ft peer 1

  heartbeat interval 100

  heartbeat count 10

  ft-interface vlan 30

exit

ft group 1

  peer 1

  no preempt

  priority 110

  peer priority 120

  associate-context Admin

  inservice

exit

Re: ACE4710 - Install New FT Peer

Hi Surya

Thanks for the reply, good to know about only creating the Admin context. I have set the priority lower on the replacement device and will just have that as standby now. Both have the 1gig license.
