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).

permit – assigns a permit filter for IP packets.

permit icmp (for IPv6 ACLs)

To allow all or specific internet control message protocol (ICMP) messages, configure a filter.

Syntaxpermit 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-numbercommand if you know the filter’s sequence number.

•Use the no permit icmp {source address mask any host ipv6- address} {destination address any host ipv6-address} command.

Parameters

Defaults

log

(OPTIONAL) Enter the keyword log to enable the triggering

 

of ACL log messages.

threshold-in

(OPTIONAL) Enter the threshold-in-msgskeyword

msgs count

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

(OPTIONAL) Enter the keyword interval followed by the

minutes

time period in minutes at which ACL logs must be generated.

 

The 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.

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.
