VRRP error - Invalid VRRP ID - changing versions (v2 and v3)

[jabrockson]

I've taken over a small network of SG500X switches that were configured by the previous admin. I've noticed tons of errors on the VRRP Statistics page under these two headings: "Invalid VRRP ID" and "Invalid Protocol Number".  So that prompted me to check the VRRP version on each virtual router. Half my routers are set to just "V3", while the other half are set to "V2 and V3". I only have 6 virtual routers total.

I'm thinking that if I change the ones that are set to "both" to just "V3" only, those errors will go away. 

My question is, what type of network interruption (if any) should I expect when I change the version setting?

Any ideas regarding my question above? I just want to know if there will be any interruption in the network if I change the VRRP version while the switches are in production.

Hi,

It is advised to perform this activity with a proper downtime. You will loss Virtual IP connection (If changing on Master switch) for a while. How much time? It depends on your activities.

First, make a configuration file on a notepad and just keep a copy and past task on the router.

Yes, your error message will go becuase VRRPv3 is incompatible with VRRPv2.
