Users Guide

• Use the no seq sequence-number command, if you know the lter’s sequence number.
• Use the no deny 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 /prex format (/x) or A.B.C.D. The mask, when specied in
A.B.C.D format, may be either contiguous or non-contiguous.
any Enter the keyword any to specify that all routes are subject to the lter.
host ip-address Enter the keyword host then 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 this keyword dscp to deny a packet based on the DSCP value. The range is from 0
to 63.
count (OPTIONAL) Enter the keyword count to count packets processed by the lter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the lter.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL entry.
The range is from 0 to 254 (where 0 is the highest priority and 254 is the lowest; lower
order numbers have a higher priority) If you did 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.
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.
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 ve minutes. By default, ow-based monitoring is not enabled.

Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Added the support for ow-based monitoring on the MXL 10/40GbE Switch IO Module.
9.3(0.0) Added the support for logging ACLs on the MXL 10/40GbE Switch IO Module.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
The order option is relevant in the context of the Policy QoS feature only. For more information, refer to the
Quality of Service chapter of the Dell Networking OS Conguration Guide.
When the congured maximum threshold is exceeded, generation of logs is stopped. When the interval at which
ACL logs are congured 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 congured
threshold is exceeded, it is re-enabled for this new interval.
