Cisco ASA 5585X Failover No Working

Hi all,

 

I issued the Failover Active on Standby ASA and No Failover Active on Active ASA but both ASA all cannot change the state. At the time after issuing this command, the SSH session on the ASA also drop and has to restart session again.

 

The two ASA now with the Secondary Set acts as Active and Primary Set acts as Standby.

Attach is the snapshot for the Failover state and configuration.

 

Please let me know what is the problem and how to resolve it? Thanks!

 

regards,

Tan Tang Suan

There is no equivalent concept for preempt in ASA High Availability setup.

The preempt feature with HSRP/VRRP is designed to allow you to always favor one device to be active. With ASA that feature is not available.

Are your command outputs edited? an ASA HA pair should both be showing the same hostname. We use the prompt to add the role and state.

If you connect with anything other than the unique management address, issuing "no failover active" is normally expected to disconnect your ssh session as the other unit will assume the configured address for all data plane interfaces.

Hi Marvin,

 

Thanks to your reply. Yes, the command outputs have been edited to show which one is primary and secondary. Now, the primary is on Standby and secondary is on Active.

Now even I issue command Failover active in the Standby ASA, the SSH session also drops.

From the Failover state, there is COMM ERROR in the Standby ASA. Is this shows abnormality on this Failover setup?

By the way, I have some logs in the Standby ASA, do you need it?

 

Thanks and regards,

Tangsuan Tan

Anytime you issue "failover active" from a unit that is not currently active it will assume the active role and change its dataplane interface address(es) accordingly. That will cause the current ssh session to be terminated (assuming you've ssh'd into a dataplane interface).

You should not have a "comm error". That most commonly indicates that the failover link connection is not active.

Hi Marvin,

 

I have done repeating 100 times ping on all the four failover IP address 10.1.1.2, 10.1.1.1, 10.2.1.1 and 10.2.1.2. The results are all smooth.

 

These two ASA are placed side by side in two different racks. The failover cable distance between them are short.

I copy and paste here the log for the Standby ASA which is having a lot of time of records I activae the "No failover active" on the Active ASA but it cannot succeed.

 

 

 

Please let me know any finding you can help on this problem.

 

Thanks and hope to hear you soon.

Those are normal log messages associated with failover. From them it shows member state of "Standby Ready" which we would not expect if there's a COMM FAILURE as you indicated earlier.

Don't use the standby option when configuring your management interfaces. Primary unit should have one address and secondary unit another one. That way you can always log into the right one and not have to know which is in Active or Standby role at the time.

Hi Marvin,

 

Many thanks to your reply.

 

May I know that this standby option is it similar to preempt action to make the first IP address always active?

 

Is it there is a preempt command for Cisco ASA so that we can use the preempt command instead?

 

thanks and regards,

tangsuan

@Marvin Rhoads just five cents from me - there IS preempt in ASA failover groups. You can deliberately set one unit as preffered, this also helps with steps during upgrade as there is one manual step less (switching over between stby and active again after reload):

failover group 1
preempt
failover group 2
secondary
preempt

@tomeq82 the "failover group" command is only applicable on devices configured for multiple context mode.
