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).
