Enabling & Disabling ARP Inspection
◆
ARP Inspection is controlled on a global and VLAN basis.
◆
By default, ARP Inspection is disabled both globally and on all VLANs.
■
If ARP Inspection is globally enabled, then it becomes active only on
the VLANs where it has been enabled.
■
When ARP Inspection is enabled globally, all ARP request and reply
packets on inspection-enabled VLANs are redirected to the CPU and
their switching behavior handled by the ARP Inspection engine.
■
If ARP Inspection is disabled globally, then it becomes inactive for
all VLANs, including those where inspection is enabled.
■
When ARP Inspection is disabled, all ARP request and reply packets
will bypass the ARP Inspection engine and their switching behavior
will match that of all other packets.
■
Disabling and then re-enabling global ARP Inspection will not affect
the ARP Inspection configuration of 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 enabled
globally again.
◆
The ARP Inspection engine in the current firmware version does not
support ARP Inspection on trunk ports.

Inspection Validation globally. Any combination of the following checks
can be active concurrently.

Destination MAC – Checks the destination MAC address in the
Ethernet header against the target MAC address in the ARP body.
This check is performed for ARP responses. When enabled, packets
