new interval commences from zero. If ACL logging was stopped previously
because the configured threshold is exceeded, it is re-enabled for this new interval.
If ACL logging is stopped because the configured threshold is exceeded, it is re-
enabled after the logging interval period elapses. ACL logging is supported for
standard and extended IPv4 ACLs, IPv6 ACLs, and MAC ACLs. You can configure
ACL logging only on ACLs that are applied to ingress interfaces; you cannot enable
logging for ACLs that are associated with egress interfaces.

Commands
• deny — assign a filter to deny IP traffic.
• deny tcp — assign a filter to deny TCP traffic.
deny arp (for Extended MAC ACLs)
Configure an egress filter that drops ARP packets on egress ACL supported line cards. (For more
information, refer to your line card documentation).
Syntax
deny arp {destination-mac-address mac-address-mask | any} vlan
vlan-id {ip-address | any | opcode code-number} [count [byte]]
[order] [log [interval minutes] [threshold-in-msgs [count]]
[monitor]
To remove this filter, you have two choices:
• Use the no seq sequence-number command if you know the filter’s
sequence number.
• Use the no deny arp {destination-mac-address mac-address-mask
| any} vlan vlan-id {ip-address | any | opcode code-number}
command.
Parameters
log (OPTIONAL) Enter the keyword log to enable the triggering
of ACL log messages.
threshold-in msgs
count
(OPTIONAL) Enter the threshold-in-msgs keyword
followed by a value to indicate the maximum number of
ACL logs that can be generated, exceeding which the
generation of ACL logs is terminated with the seq, permit,
or
deny commands. The threshold range is from 1 to 100.
interval minutes (OPTIONAL) Enter the keyword interval followed by the
time period in minutes at which ACL logs must be
generated. The time interval range is from 1 to 10 minutes.
monitor (OPTIONAL) Enter the keyword monitor when the rule is
describing the traffic that you want to monitor and the ACL
in which you are creating the rule is applied to the
monitored interface.
