configure iparp add proxy
configure iparp add proxy [<ipNetmask> | <ip_addr> {<mask>}] {vr <vr_name>}
{<mac>} {always}
Description
Configures the switch to respond to ARP Requests on behalf of devices that are incapable of doing so.
Syntax Description
Default
If you do not specify a virtual router, the current virtual router context is used.
Usage Guidelines
When
mask
is not specified, an address with the mask 255.255.255.255 is assumed. When
mac_address
is not specified, the MAC address of the switch is used in the ARP Response. When
always
is specified,
the switch answers ARP Requests without filtering requests that belong to the same subnet of the
receiving router interface.
After IP ARP is configured, the system responds to ARP Requests on behalf of the device as long as the
following conditions are satisfied:
●
The valid IP ARP Request is received on a router interface.
●
The target IP address matches the IP address configured in the proxy ARP table.
●
The source IP address is not on the same subnet as the target address (unless the always flag is set).
After all the proxy ARP conditions have been met, the switch formulates an ARP Response using the
configured MAC address in the packet.
The default maximum number of proxy entries is 256, but can be increased to 4096 by using the
following command:
configure iparp max_proxy_entries <max_proxy_entries>
ipNetmask
Specifies an IP address/mask length.
ip_addr
Specifies an IP address.
mask
Specifies a subnet mask.
mac_address
Specifies a MAC address.
always
Specifies that the switch responds regardless of the VLAN that the request
arrives from.
vr_name
Specifies a VR name.
