Example (Error Messages) 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 accessgroup 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 accesscontrol command is disabled. A message appears identifying the error (refer to the following Example).
