Folks, I need some guidance about how and what people use in datacenter to control strom, let me give my example, we have almost 180 Cisco nexus 9K/3K/5K switches and all of the switch configured in vPC, at present i have ~2500 physical servers/Virtual servers in multiple VLANs ( not single L2 broadcast domain ). at present we don't have any specific configuration on switch to control any kind of storm ( I am not sure if they are default ON ), following common configuration i have on all switches connected hosts. you can see i don't have any kind of storm-control command on interface level. ( I am not sure what level i should use and what are the best practice)
interface port-channel121 description ### host www.foo.example.com ### switchport mode trunk switchport trunk native vlan 40 switchport trunk allowed vlan 10,20,30,40,50,60 spanning-tree port type edge trunk spanning-tree bpduguard enable speed 10000 vpc 121
storm-control

- What other folks using in datacenter to monitor any kind of storm or method to prevent or protect network?
- How big my L2 domain can be in best practice? ( example 1000 hosts in single L2 domain is safe or it can handle more than that?)
