If an ambiguous access control list rules, the debug ip packet access-control command is disabled. A
message appears identifying the error (refer to the following Example).

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).
C9000 Series
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.

Usage Information
When the configured maximum threshold is exceeded, generation of logs is stopped. When the interval at which
ACL logs are configured to be recorded expires, the subsequent, fresh interval timer is started and the packet
