ACE 4710 FT ip address change

[David.Pellat]

Hi,

Does anyone know of a document that details the steps to chenge the FT ip addresses of a pair of Cisco  4710 whilst they are running in a production environment without causing an outage?

  Would the steps be:

On the secondary unit:

hbs-syd04-lb01

ft interface vlan 417

 ip address 172.30.254.221 255.255.255.252

 peer ip address 172.30.254.222 255.255.255.252

Then on the primary unit:

hbs-syd04-lb01

ft interface vlan 417

 ip address 172.30.254.221 255.255.255.252

 peer ip address 172.30.254.222 255.255.255.252

Or Vice Versa?

Thanks

To avoid any risk, i would proceed as following:

1/ Make sure that all contexts on primary have higher priority. Make sure preemption is enabled for all contexts.

2/ Isolate secondary ACE (eg shutdown ports on the switch). From that moment, both ACEs should be active

3/ Perform the config changes

4/ Restore connectivity with secondary ACE. Context on secondary should become FSM_FT_STATE_STANDBY_HOT
