Access Control Lists (ACL)
Enter the application layer port number. Enter two port
numbers if you are using the range logical operand. The
range is from 0 to 65535.
The following list includes some common TCP port
numbers:
•
23 = Telnet
•
20 and 21 = FTP
•
25 = SMTP
•
169 = SNMP
Enter the IP address of the network or host to which the
packets are sent.
Enter a network mask in /prefix format (/x) or A.B.C.D. The
mask, when specified in A.B.C.D format, may be either
contiguous or non-contiguous.
(OPTIONAL) Enter the keyword count to count packets the
filter processes.
(OPTIONAL) Enter the keyword byte to count bytes the filter
processes.
(OPTIONAL) Enter the keyword order to specify the QoS
priority for the ACL entry. The range is from 0 to 254 (where
0 is the highest priority and 254 is the lowest; lower-order
numbers have a higher priority). If you do not use the
keyword order, the ACLs have the lowest order by default
(255).
Enter the keyword fragments to use ACLs to control packet
fragments.
(OPTIONAL) Enter the keyword log to enable the triggering
of ACL log messages.
(OPTIONAL) Enter the threshold-in-msgs keyword
followed by a value to indicate the maximum number of ACL
logs that can be generated, exceeding which the generation
of ACL logs is terminated with the seq, permit, or deny
commands. The threshold range is from 1 to 100.
(OPTIONAL) Enter the keyword interval followed by the
time period in minutes at which ACL logs must be generated.
The threshold range is from 1 to 10 minutes.
(OPTIONAL) Enter the keyword monitor when the rule is
describing the traffic that you want to monitor and the ACL
in which you are creating the rule is applied to the monitored
interface.
