high latency after HA failover

L3 Networker

Hello team,

 

I have an HA active/passive with a couple of PA-3250. After failover from active to passive there are a high latency for all the connections and some Http/https sessions cannot be established. I see in the traffic logs many aged out sessions and tcp-rst-from-server and also tcp-rst-from-client. After one minute aprox. the system gets stable. Is this expected behavior?

 

 

Thanks and Regards,

Marcos.

@Carracido,

It can be expected behaviour depending on the configuration. 

You aren't by chance using LACP aggregates for anything are you? 

Hi BPry,

 

Thanks for you answer.

 

No I´m not using LCAP.

Marcos.

@Carracido,

Then I really wouldn't expect that much of a delay unless your hitting an issue with STP. Have you verified that you aren't just hitting a normal delay as the network reconverges following the failover? 

Hi i'm experiencing same issue here but i have 1 lacp connection. How should it lead to high latencies?
