Access Control Lists (ACL) | 211
seq arp
e
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; refer to your line card
documentation for specifications.
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] | log] [order]
[monitor]
To remove this filter, use the no seq sequence-number command.
Parameters
Defaults
Not configured.
Command Modes
CONFIGURATION-EXTENDED-ACCESS-LIST
sequence-number
Enter a number from 0 to 4294967290.
deny Enter the keyword deny to drop all traffic meeting the filter criteria.
permit Enter the keyword permit to forward all traffic meeting the filter 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 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.
