ExtremeWare XOS 10.1 Command Reference Guide 431
configure iparp delete proxy
configure iparp delete proxy [<ip_addr> {<mask>} {vr <vr_name>} | all]
Description
Deletes one or all proxy ARP entries.
Syntax Description
Default
The VR is VR-2.
Usage Guidelines
Proxy ARP can be used for two purposes:
1 To support host that cannot process ARP traffic. In this case, the switch answers the ARP Request for
that host.
2 To hide the IP topology from the host. The network administrator can configure a large network on
the host machine (16-bit mask) and a smaller network on each router interface (for example, 22-bit
mask). When the host sends ARP Request for another host on another subnet, the switch answers
the ARP Request and all subsequent traffic will be sent directly to the router.
You can configure up to 64 proxy ARP entries. When the mask is not specified, then software will
assume a host address (that is, a 32-bit mask). When the MAC address is not specified, then the
software uses the switch’s MAC address as the proxy host. Always should be specified for type-1 usage,
not always is the default (type-2).
Example
The following command deletes the IP ARP proxy entry 100.101.45.0/24:
configure iparp delete proxy 100.101.45.0/24
ip_addr Specifies an IP address.
mask Specifies a subnet mask.
all Specifies all ARP entries.
vr_name Specifies a VR name.
