Configuring IP Routers and Interfaces
2-41
Parameter: Proxy
Default: Off
Options: On | Off
Function: Specifies whether this interface uses Proxy ARP to respond to ARPs for a
remote network.
Instructions: Select On to enable Proxy ARP on this interface. In order to enable Proxy
ARP, you must have set the ARP parameter to Enable for this interface.
When you enable Proxy ARP, the IP router assumes responsibility for IP
datagrams destined for the remote network. To enable Proxy ARP for
subnets reachable via a default route, also set the Enable Default Route
for Subnets parameter to Enable. To enable Proxy ARP for remote
destinations on other networks, set the Nonlocal ARP Destination
parameter to Accept. Select Off to disable Proxy ARP on this interface.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.1.4.1.14
Parameter: Host Cache
Default: Off
Options: Off | 120 | 180 | 240 | 300 | 600 | 900 | 1200 (seconds)
Function: Specifies whether the IP router times out entries in the address-resolution
cache for this interface, and specifies the timeout interval in seconds if the
interface does time out entries. The address-resolution cache contains
host physical addresses learned by means of ARP or Proxy ARP. A host
entry is timed out (deleted) if the IP router sends no traffic destined for
that host within the specified timeout period.
Instructions: Select Off to disable timeout on this interface; the IP router does not time
out address-resolution cache entries. Select one of the other options to
enable timeout with a timeout interval equal to the value you select (for
example, 120 seconds); the IP router removes address-resolution cache
entries that have not been accessed within the specified number of
seconds. Once an entry is removed, the IP router must use ARP to re-
acquire the physical-level address.
