nv show system control-plane acl

Shows the control plane ACLs configured on the switch. You use control plane ACLs to apply a single rule for all packets forwarded to the CPU regardless of the source interface or destination interface on the switch. Control plane ACLs allow you to regulate traffic forwarded to applications on the switch with more granularity than traps and to configure ACLs to block SSH from specific addresses or subnets.
