ip access-list standard — congures a standard IP access list.
resequence access-list — Displays the current conguration.
permit (for Extended IP ACLs)
To pass IP packets meeting the lter criteria, congure a lter.
Syntax
permit {source mask | any | host ip-address} {destination mask | any | host ip-
address} [count [bytes]] [dscp value] [order] [fragments] [log [interval
minutes] [threshold-in-msgs [count]] [monitor]
To remove this lter, you have two choices:
• Use the no seq sequence-number command if you know the lter’s sequence number.
•
Use the no deny {source mask | any | host ip-address} {destination mask | any |
host ip-address} command.
Parameters
source Enter the IP address in dotted decimal format of the network from which the packet was
sent.
mask (OPTIONAL) Enter a network mask in /prex format (/x) or A.B.C.D. The mask, when
specied in A.B.C.D format, may be either contiguous or non-contiguous.
any Enter the keyword any to specify that all routes are subject to the lter.
host ip-address Enter the keyword host then the IP address to specify a host IP address or hostname.
count (OPTIONAL) Enter the keyword count to count packets processed by the lter.
bytes (OPTIONAL) Enter the keyword bytes to count bytes processed by the lter.
dscp (OPTIONAL) Enter the keyword dcsp to match to the IP DCSCP values.
order (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).
fragments Enter the keyword fragments to use ACLs to control packet fragments.
log (OPTIONAL) Enter the keyword log to enable the triggering of ACL log messages.
threshold-in msgs
count
(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.
interval minutes (OPTIONAL) Enter the keyword interval followed by the time period in minutes at
which ACL logs must be generated. The interval range is from 1 to 10 minutes.
monitor (OPTIONAL) Enter the keyword monitor when the rule is describing the trac that you
want to monitor and the ACL in which you are creating the rule is applied to the
monitored interface.
Defaults By default, 10 ACL logs are generated if you do not specify the threshold explicitly. The default frequency at which
ACL logs are generated is ve minutes. By default, ow-based monitoring is not enabled.
