permit arp (for Extended MAC ACLs)
Congure a lter that forwards ARP packets meeting this criteria. This command is supported only on 12-port GE line cards with
SFP optics; refer to your line card documentation for specications.
Syntax
permit arp {destination-mac-address mac-address-mask | any} vlan vlan-id
{ip-address | any | opcode code-number} [count [byte]] [order] [fragments]
[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 {destination-mac-address mac-address-mask | any} vlan vlan-id {ip-
address | any | opcode code-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. 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.
monitor (OPTIONAL) Enter the keyword monitor when the rule is describing the trac
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 ve minutes. By default, ow-based monitoring is
not enabled.
