CLI Guide
seq arp
Congure an egress lter with a sequence number that lters ARP packets meeting this criteria. This command is supported only on 12-
port GE line cards with SFP optics. For specications, refer to your line card documentation.
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 lter, use the no seq sequence-number command.
Parameters
sequence-number Enter a number from 0 to 4294967290.
deny Enter the keyword deny to drop all trac meeting the lter criteria..
permit Enter the keyword permit to forward all trac meeting the lter criteria.
destination-mac-
address mac-
address-mask
Enter a MAC address and mask in the nn:nn:nn:nn:nn format.
For the MAC address mask, specify which bits in the MAC address must match.
The MAC ACL supports an inverse mask; therefore, a mask of ::::: allows entries
that do not match and a mask of 00:00:00:00:00:00 only allows entries that match
exactly.
any Enter the keyword any to match and drop any ARP trac on the interface.
vlan vlan-id
Enter the keyword vlan followed by the VLAN ID to lter trac associated with a
specic VLAN. The range is 1 to 4094 and 1 to 2094 for ExaScale (you can use IDs 1 to
4094). To lter all VLAN trac specify VLAN 1.
ip-address Enter an IP address in dotted decimal format (A.B.C.D) as the target IP address of the
ARP.
opcode code-
number
Enter the keyword opcode and then enter the number of the ARP opcode. The range is
1 to 16.
count (OPTIONAL) Enter the keyword count to count packets the lter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes the lter 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).
log (OPTIONAL) Enter the keyword log to enable the triggering of ACL log messages.
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.
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.
