seq arp (for Extended MAC ACLs)
Configure an egress filter with a sequence number that filters ARP packets meeting this criteria. This command is supported only on 12-
port GE line cards with SFP optics. For specifications, refer to your line card documentation.
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
seq sequence-number {deny | permit} arp {destination-mac-address mac-address-
mask | any} vlan vlan-id {ip-address | any | opcode code-number} [count [byte]]
[order] [log [interval minutes] [threshold-in-msgs [count]] [monitor]
To remove this filter, use the no seq sequence-number 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 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. You can enter a
threshold in the range of 1-100.
interval minutes (OPTIONAL) Enter the keyword interval followed by the time period in minutes at
which ACL logs must be generated. You can enter an interval in the range of 1-10 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.
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 5 minutes. By default, flow-based monitoring is not
enabled.

Switch IO Module platforms.
Usage Information
When the configured maximum threshold is exceeded, generation of logs is stopped. When the interval at which
ACL logs are configured 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 configured
threshold is exceeded, it is reenabled for this new interval.
If ACL logging is stopped because the configured threshold is exceeded, it is reenabled after the logging interval
period elapses. ACL logging is supported for standard and extended IPv4 ACLs, standard and extended IPv6
ACLs, and standard and extended MAC ACLs. You can configure ACL logging only on ACLs that are applied to
ingress interfaces; you cannot enable logging for ACLs that are associated with egress interfaces.
You can activate flow-based monitoring for a monitoring session by entering the flow-based enable command in
the Monitor Session mode. When you enable this capability, traffic with particular flows that are traversing
through the ingress and egress interfaces are examined and, appropriate ACLs can be applied in both the ingress
