Command
History
Version 9.3.0.0 Added support for logging of ACLs on the S4810, S4820T,
Z9000, M I/O Aggregator and MXL 10/40GbE Switch IO
Module platforms.
Usage
Information
When the configured maximum threshold is exceeded, generation of logs is
stopped. When the interval at which ACL logs are configured to be recorded
expires, the subsequent, fresh interval timer is started and the packet count for that
new interval commences from zero. If ACL logging was stopped previously
because the configured threshold is exceeded, it is reenabled for this new interval.
If ACL logging is stopped because the configured threshold is exceeded, it is
reenabled after the logging interval period elapses. ACL logging is supported for
standard and extended IPv4 ACLs, standard and extended IPv6 ACLs, and standard
and extended MAC ACLs. You can configure ACL logging only on ACLs that are
applied to ingress interfaces; you cannot enable logging for ACLs that are
associated with egress interfaces.
permit icmp (for Extended IP ACLs)
Configure a filter to allow all or specific ICMP messages.
NOTE: Only the options that have been newly introduced are described here. For a complete
description on all of the keywords and variables that are available with this command, refer the
respective Command Reference Guide of the applicable platform of the Release 9.2.0.0
documentation set.
Syntax
permit icmp {source mask | any | host ip-address} {destination
mask | any | host ip-address} [dscp] [message-type] [count
[byte]] [order] [fragments] [log [interval minutes] [threshold-
in-msgs [count]]
To remove this filter, you have two choices:
• Use the no seq sequence-number command if you know the filter’s
sequence number.
• Use the no permit icmp {source mask | any | host ip-address}
{destination mask | any | host ip-address} command.
Parameters
log (OPTIONAL) Enter the keyword log to enable the triggering
of ACL log messages.
