◆
When ARP Inspection is enabled globally with this command, it
becomes active only on those VLANs where it has been enabled with
the
ip arp inspection vlan
command.
◆
When ARP Inspection is enabled globally and enabled on selected
VLANs, all ARP request and reply packets on those VLANs are
redirected to the CPU and their switching is handled by the ARP
Inspection engine.
◆
When ARP Inspection is disabled globally, it becomes inactive for all
VLANs, including those where ARP Inspection is enabled.
◆
When ARP Inspection is disabled, all ARP request and reply packets
bypass the ARP Inspection engine and their manner of switching
matches that of all other packets.
◆
Disabling and then re-enabling global ARP Inspection will not affect the
ARP Inspection configuration for any VLANs.
◆
When ARP Inspection is disabled globally, it is still possible to configure
ARP Inspection for individual VLANs. These configuration changes will
only become active after ARP Inspection is globally enabled again.
