Cisco 3850 SSO and NSF failover time

[Russ Kwong]

Dear Member,

I m trying to setup a network with few second fail-over with Cisco 3850 stack, C3850 support SSO and NSF on OSPF.

However, when the Master fails, Slave take up the role and re-learn routing information and around 10 sec to fail-over.

May any brothers have this experience and 10 sec fail-over should be the normal behavior or can be enhance?

Attach diagram for reference.

Regards

Russ

Hi,

10 seconds is a little too high.

can you add this command to the stack and test again?

stack-mac persistent timer 0
