Parameter
None
Description
Use the arp proxy source-vlan enable command to enable the inbound VLAN ARP
proxy function to process the ARP requests in the same VLAN, so as to realize the
Layer 3 connectivity between the Layer 2 isolated ports.
Use the undo arp proxy source-vlan enable command to enable the ARP proxy only
for the ARP requests between different VLANs, ARP requests in the same VLAN will
not be processed by the ARP proxy. By default, the incoming VLAN ARP proxy function
is disabled, and when enabled, the ARP proxy function only processes ARP requests
between different VLANs.
Note that, the incoming VLAN ARP function takes effect only after the ARP proxy
function is enabled.
Related command: arp proxy enable, display arp proxy.
Example
# With ARP proxy enabled, enable the incoming VLAN ARP proxy for VLAN 2.
