When you use the log option, the CP processor logs details about the packets that match.

Depending on how many packets match the log entry and at what rate, the CP may become

busy as it has to log these packets' details.

Extended IP ACL Commands

When an ACL is created without any rule and then applied to an interface, ACL behavior reflects an implicit permit.

The following commands configure extended IP ACLs, which in addition to the IP address, also examine the packet's

protocol type.

C-Series and S-Series platforms (except the S4810) support Ingress IP ACLs only.

The S4810 and Z9000 support both Ingress and Egress IP ACLs.

NOTE: Also refer to the

Configure a filter that drops IP packets meeting the filter criteria.

C-Series, E-Series, S-Series, Z-Series, S4810

deny {ip | ip-protocol-number} {source mask | any | host ip-

address} {destination mask | any | host ip-address} [count

[byte] | log] [dscp value] [order] [monitor] [fragments]

To remove this filter, you have two choices:

The order option works across ACL groups that have been applied on an interface

via the QoS policy framework.

The order option takes precedence over seq sequence-number.

If sequence-number is not configured, the rules with the same order value are

ordered according to their configuration order.

If sequence-number is configured, the sequence-number is used as a tie breaker

for rules with the same order.

NOTE: When ACL logging and byte counters are configured simultaneously, byte counters

may display an incorrect value. Configure packet counters with logging instead.

– configures a filter to drop packets.

– configures a filter to forward packets.

Commands Common to all ACL Types

Use the no seq sequence-number command if you know the filter's sequence

Use the no deny {ip | ip-protocol-number} {source mask | any

| host ip-address} {destination mask | any | host ip-

address} command.

Enter the keyword ip to configure a generic IP access list. The

keyword ip specifies that the access list denies all IP protocols.
