permit arp
e
Configure a filter 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 specifications.
Syntax permit arp { destination-mac-address mac-address-mask | any } vlan vlan-id { ip-address |
any | opcode code-number } [ count [ byte ] | log ] [ order ] [ monitor ] [ fragments ]
To remove this filter, use one of the following:
• Use the no seq sequence-number command syntax if you know the filter’s sequence number
or
• Use the no permit arp { destination-mac-address mac-address-mask | any } vlan vlan-id
{ ip-address | any | opcode code-number } command.
Parameters
Defaults Not configured.
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 ff:ff:ff:ff:ff:ff
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 traffic on the interface.
vlan vlan-id
Enter the keyword
vlan
followed by the VLAN ID to filter traffic associated
with a specific VLAN.
Range: 1 to 4094, 1-2094 for ExaScale (can used IDs 1-4094)
To filter all VLAN traffic 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
followed by the number of the ARP opcode.
Range: 1 to 16.
count
(OPTIONAL) Enter the keyword
count
to count packets processed by the
filter.
byte
(OPTIONAL) Enter the keyword
byte
to count bytes processed by the
filter.
log
(OPTIONAL, E-Series only) Enter the keyword
log
to have the information
kept in an ACL log file.
order
(OPTIONAL) Enter the keyword
order
to specify the QoS priority for the
ACL entry.
Range: 0-254 (where 0 is the highest priority and 254 is the lowest; lower
order numbers have a higher priority)
Default: If the order keyword is not used, the ACLs have the lowest order by
default (255).
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 will be applied to the monitored interface. For details, see the section
“Flow-based Monitoring” in the Port Monitoring chapter of the
FTOS
Configuration Guide .
fragments
Enter the keyword
fragments
to use ACLs to control packet fragments.
