Usage Guidelines

Usage Scenario

When hosts are located on the same network segment and belong to the same VLAN configured with port isolation, you can run the arp-proxy inner-sub-vlan-proxy enable command on the device connected to the hosts to enable intra-VLAN proxy ARP, implementing IP address resolution between the hosts.

Precautions

QinQ sub-interfaces, Dot1q sub-interfaces, QinQ Stacking sub-interfaces and QinQ Mapping sub-interfaces do not support proxy ARP within a VLAN.

Example

# Enable intra-VLAN proxy ARP on VLANIF 100.
