deny (for IPv6 ACLs)
Configure a filter that drops IPv6 packets that match the filter criteria.
Syntax
deny {ipv6-protocol-number | icmp | ipv6 | tcp | udp} [count [byte]] [dscp 
value] [order] [fragments] [log [interval minutes] [threshold-in-msgs [count]] 
[monitor] [no-drop]
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 {ipv6-protocol-number | icmp | ipv6 | tcp | udp} 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. 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 time interval range is from 1 to 10 minutes.
monitor (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.
no-drop Enter the keywords no-drop to match only the forwarded packets.
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 five minutes. By default, flow-based monitoring is not 
enabled.

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 re-enabled for this new interval.
