Usage
Information
Use the count option to stop packets from flooding the user terminal when debugging is
turned on.
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 Example below). 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: 0 to 255
• Internet Control Message Protocol (icmp) but not the ICMP message type (0-255)
• 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).
