Command History
Usage Guidelines
After entering the
arp access-list
command, you enter ARP access-list configuration mode, and these
configuration commands are available:
•
default
: returns a command to its default setting.
•
deny
: specifies packets to reject. For more information, see the
“deny (ARP access-list
configuration)” section on page 2-101
.
•
exit
: exits ARP access-list configuration mode.
•
no
: negates a command or returns to default settings.
•
permit
: specifies packets to forward. For more information, see the
“permit (ARP access-list
configuration)” section on page 2-384
.
Use the
permit
and
deny
access-list configuration commands to forward and to drop ARP packets based
on the specified matching criteria.
When the ARP ACL is defined, you can apply it to a VLAN by using the
ip arp inspection filter vlan
global configuration command. ARP packets containing only IP-to-MAC address bindings are compared
to the ACL. All other types of packets are bridged in the ingress VLAN without validation. If the ACL
permits a packet, the switch forwards it. If the ACL denies a packet because of an explicit deny
statement, the switch drops the packet. If the ACL denies a packet because of an implicit deny statement,
the switch compares the packet to the list of DHCP bindings (unless the ACL is
static
, which means that
packets are not compared to the bindings).
acl-name
Name of the ACL.
