Common IP ACL Commands
The following commands are available within both IP ACL modes (Standard and Extended) and do not
have mode-specific options. When an access-list (ACL) is created without any rule and then applied to
an interface, ACL behavior reflects an implicit permit.
c and s (non-S4810) platforms support Ingress IP ACLs only.
The and z support both Ingress and Egress IP ACLs.
The following commands allow you to clear, display, and assign IP ACL configurations.
• access-class
• clear counters ip access-group
• ip access-group
• ip control-plane egress-filter
• show ip accounting access-list
