Description
Use the arp proxy enable command to enable proxy ARP.
Use the undo arp proxy enable command to disable proxy ARP.
You can use the arp proxy enable command to enable the switch to provide Layer 3
connectivity between hosts that reside in the same network segment but connect with
different VLAN interfaces on the switch.
By default, proxy ARP is disabled.
Related commands: display arp proxy.
Examples
# Enable proxy ARP on VLAN-interface 2.
<H3C> system-view

1.1.7 arp proxy source-vlan enable
Syntax
arp proxy source-vlan enable
undo arp proxy source-vlan enable
View
VLAN interface view
Parameters
None
Description
Use the arp proxy source-vlan enable command to enable intra-VLAN proxy ARP, so
that proxy ARP is able to process intra-VLAN ARP requests to provide Layer 3
connectivity between Layer 2 isolated ports in the same VLAN.
Use the undo arp proxy source-vlan enable command to disable intra-VLAN proxy
ARP, so that proxy ARP only processes inter-VLAN ARP requests instead of
intra-VLAN ARP request.
By default, intra-VLAN proxy ARP is disabled, and proxy ARP only processes
inter-VLAN ARP requests after it is enabled.
Note that, intra-VLAN proxy ARP can be enabled only after proxy ARP is enabled.
Related commands: arp proxy enable, display arp proxy.
