Addendum

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.
deny udp (for IPv6 ACLs)
Configure a filter to drop user datagram protocol (UDP) packets meeting the filter criteria.
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
deny udp {source address mask | any | host ipv6-address}
[operator port [port]] {destination address | any | host ipv6-
address} [operator port [port]] [count [byte]] [log [interval
minutes] [threshold-in-msgs [count]]
To remove this filter, you have two choices:
• Use the no seq sequence-number command syntax if you know the filter’s
sequence number
• Use the no deny udp {source address mask | any | host ipv6-
address} {destination address | any | host ipv6-address}
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.
interval
minutes
(OPTIONAL) Enter the keyword interval followed by the
time period in minutes at which ACL logs must be generated.
