ICMP message name
ttl-exceeded
Description
Use rule to create or edit an IPv4 advanced ACL rule. You can edit ACL rules only when the match order
is config.
Use undo rule to delete an entire IPv4 advanced ACL rule or some attributes in the rule. If no optional
keywords are provided, you delete the entire rule. If optional keywords or arguments are provided, you
delete the specified attributes.
By default, an IPv4 advanced ACL does not contain any rule.
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 will fail.
To view rules in an ACL and their rule IDs, use the display acl all command.
If an IPv4 advanced ACL is for QoS traffic classification or packet filtering:
• Do not specify the vpn-instance keyword.
Do not specify neq for the operator argument.
•
The counting keyword (even if specified) does not take effect for QoS traffic classification.
•
Related commands: acl, display acl, step, and time-range.
