Reference Guide

The access-group option supports only the equal to (eq) operator in TCP ACL
rules. Port operators not equal to (neq), greater than (gt), less than (lt), or range
are not supported in access-group option (refer to the following example). ARP
packets (arp) and Ether-type (ether-type) are also not supported in the access-
group option. The entire rule is skipped to compose the filter.
The access-group option pertains to:
• IP protocol number: from 0 to 255
• Internet control message protocol (icmp) but not the ICMP message type (from
0 to 255)
• Any internet protocol (ip)
• Transmission Control Protocol (tcp) but not on the rst, syn, or urg bits
• User Datagram Protocol (udp)
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).

To remove this filter, you have two choices:
• Use the no seq sequence-number command if you know the filter’s
sequence number.
