About applying ACLs to the Control Plane

ACLs can be applied to the Control Plane to control how switch management traffic flows in the switch, whether introduced into the switch through the front switch ports and/or the OOBM (Out of Band Management) port.
NOTE:

The term "Control Plane ACL" is not used because "Control Plane" is not a type of ACL. Rather, "Control Plane" identifies the switch management traffic to which ACLs can be applied.

NOTE:

ACLs applied to the Control Plane must be defined carefully to not accidentally disconnect your active management session that is being used to apply the ACL or to interrupt network services such as routing protocols. If you lose connectivity because of a problem with your Control Plane ACL, you can still reconfigure your switch using the serial console which is unaffected by Control Plane ACLs.
