permit arp
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.
E-Series
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, you have two choices:
• Use the
no seq sequence-number
command if you know the filter’s sequence
number.
• Use the
{ destination-mac-address mac-address-mask | any}
vlan vlan-id { ip-address | any | opcode code-number }
command.
Parameters
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 specific Ethernet traffic on
the interface.
vlan vlan-id Enter the keyword
vlan
and then enter the VLAN ID to filter traffic
associated with a specific VLAN. The range is 1 to 4094 and 1 to 2094
for ExaScale (you can use IDs 1 to 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. The range is 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. 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).
