Command Usage
• 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 (page 4-192).
• 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.
Example
This command enables ARP Inspection for a specified VLAN or range of VLANs.
