CLI Guide

permit icmp
Configure a filter to allow all or specific ICMP messages.
C9000 Series
Syntax
permit icmp {source mask | any | host ip-address} {destination mask | any |
host ip-address} [dscp] [count [bytes]] [order] [fragments] [log [interval
minutes] [threshold-in-msgs [count]] [monitor]
To remove this filter, you have two choices:
● Use the no seq sequence-number command if you know the filter’s sequence number.
● Use the no permit icmp {source mask | any | host ip-address} {destination
mask | any | host ip-address} command.
Parameters
source Enter the IP address of the network or host from which the packets were sent.
mask Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified
in A.B.C.D format, may be either contiguous or noncontiguous.
any Enter the keyword any to match and drop specific Ethernet traffic on the
interface.
host ip-address Enter the keyword host and then enter the IP address to specify a host IP
address.
destination Enter the IP address of the network or host to which the packets are sent.
dscp Enter the keyword dscp to deny a packet based on the DSCP value. The range is 0
to 63.
count (OPTIONAL) Enter the keyword count to count packets the filter processes.
bytes (OPTIONAL) Enter the keyword byte to count bytes the filter processes.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL
entry. The range is 0 to 254 (where 0 is the highest priority and 254 is the lowest;
lower-order numbers have a higher priority). If you do not use the keyword order,
the ACLs have the lowest order by default (255).
fragments Enter the keyword fragments to use ACLs to control packet fragments.
log (OPTIONAL) Enter the keyword log to include ACL messages in the log.
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 threshold 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. For more information, refer to the “Flow-based
Monitoring” section in the Port Monitoring chapter of the Dell Networking OS
Configuration Guide.
