Sniffing a vlan I see multiple unicast conversations. Some suspect the additional unicasts are overwhelming our file server(s), hence performance issues, hence "its the network".
switchport block unicast shuts down the DFS, so this isn't helpful troubleshooting. I see this storm-control unicast level xxx command. Some have told me this clears the interface unicast flood counters but still allows the excess unicast to hit the interface. sh mac-address-address unicast flooding command isn't supported on 12.233SFX so I need to upgrade IOS but the release notes of anything newer doesn't address unicast flooding. Any direction on how to work this would be helpful?
