specified traffic instead all traffic on the interface. This feature is particularly useful
when looking for malicious traffic. It is available for Layer 2 and Layer 3 ingress and
egress traffic. You may specify traffic using standard or extended access-lists. This
mechanism copies all incoming or outgoing packets on one port and forwards (mirrors)
them to another port. The source port is the monitored port (MD) and the destination
port is the monitoring port (MG).
deny icmp (for Extended IPv6 ACLs)
Configure a filter to drop all or specific ICMP messages.
C9000 Series
NOTE:
Only the options that have been newly introduced in Release 9.3(0.0) and Release 9.4(0.0) are
described here. For a complete description on all of the keywords and variables that are available with this
command, refer the topic of this command discussed earlier in this guide.
Syntax
deny icmp {
source address mask
| any | host
ipv6-address
}
{
destination address
| any | host
ipv6-address
} [
message-type
]
[count [byte]] | [log [interval
minutes
] [threshold-in-msgs
[
count
]] [monitor]
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 icmp {
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

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.

minutes
(OPTIONAL) Enter the keyword
