4000 Router Series ACL and QoS Command Reference

vpn-instance vpn-instance-name: Applies the rule to a VPN instance. The vpn-instance-name argument is

a case-sensitive string of 1 to 31 characters. If no VPN instance is specified, the rule applies only to

non-VPN packets.

Usage guidelines

Within an ACL, the permit or deny statement of each rule must be unique. If the ACL rule you are creating

or editing has the same deny or permit statement as another rule in the ACL, your creation or editing

attempt fails.

You can edit ACL rules only when the match order is config.

If no optional keywords are provided for the undo rule command, you delete the entire rule. If optional

keywords or arguments are provided, you delete the specified attributes.

To view rules in an ACL and their rule IDs, use the display acl all command.

Examples
