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).
