Hello.

If I clear the ARP table on a Nexus9300, will existing conns crash?

Might other negative symptoms occur?

Thank you.

Why do you need to clear all the arp - any reason ?

i do not believe exiting connection breaks since exiting connection know already where the other end.

But if this is large ARP database have some other side effects, suggest to do this in maintenance window.

once clear the arp, the switch need to broadcast and get new arp to mac resolution.

Clear specific entry instead of clear all table
