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 interval range is from 1 to 10 minutes.

permit icmp
To allow all or specic internet control message protocol (ICMP) messages, congure a lter.
Syntax
permit 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 lter, you have two choices:
• Use the no seq sequence-number command if you know the lter’s sequence number.
•
Use the no permit icmp {source address mask | any | host ipv6-address}
{destination address | any | host ipv6-address} command.
Parameters
source address Enter the IPv6 address of the network or host from which the packets were sent in the
x:x:x:x::x format then the prex length in the /x format. The range is from /0 to /128.
The :: notation species successive hexadecimal elds of zero.
mask Enter a network mask in /prex format (/x).
any Enter the keyword any to specify that all routes are subject to the lter.
host ipv6-address Enter the keyword host then the IPv6 address of the host in the x:x:x:x::x format. The ::
notation species successive hexadecimal elds of zero.
destination address Enter the IPv6 address of the network or host to which the packets are sent in the
x:x:x:x::x format then the prex length in the /x format. The range is from /0 to /128.
The :: notation species successive hexadecimal elds of zero.
