Usage
Information
To stop packets from flooding the user terminal when debugging is turned on, use
the count option.
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)
In the case of ambiguous access control list rules, the debug ip packet
access-control command is disabled. A message appears identifying the error
(refer to the Example below).
