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 ether-type (for Extended MAC ACLs)
Configure a filter that allows traffic with specified types of Ethernet packets. This command is supported
only on 12-port GE line cards with SFP optics. For specifications, refer to your line card documentation.
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 ether-type protocol-type-number {destination-mac-address
mac-address-mask | any} vlan vlan-id {source-mac-address mac-
address-mask | any} [count [byte]] [order] [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 ether-type protocol-type-number
{destination-mac-address mac-address-mask | any} vlan vlan-
id {source-mac-address mac-address-mask | any} command.
Parameters
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. You can enter a threshold in the range of 1-100.
