Increasing The Arp Timeout Value - Intermec 6400 User Manual

SECTION 3
Ensure your 6400 computer's IP address has the same
"
subnet as the computer you are trying to ping.
If the computer you want to ping is on another subnet,
a router must deliver your ping packet to it. For your
6400 computer to find the router, use one of the
following methods to enter the router's IP address:
Open the 6400 TCP/IP client DOS configuration
"
menus and enter the IP address for the Config
Parms/router parameter (page 2 7).
Open PCTCP.INI and modify the setting for the
"
following parameter, located in the
[pctcp ifcust 0] file section:
router=
Obtain the IP router address from a DHCP or
"
Bootp server (page 2 46).

Increasing the ARP Timeout Value

If ping intermittently fails with the message ARP failed"
or ARP timeout," you may need to set your ARP timeout
parameter to a higher value. An ARP must occur before
one IP node can communicate with another IP node. In a
wireless LAN, more time is required to complete the ARP
transaction than in a wired LAN. By extending the ARP
timeout value, your 6400 computer waits longer for the
ARP transaction to complete.
To set the ARP timeout:
1. Use a text editor to open PCTCP.INI.
2. Modify the setting for the following parameter, located
in the [pctcp kernel] file section:
arp-timeout=
The range is 1 to 5000, in milliseconds. The default is
1500 milliseconds. If no timeout is specified, it is
automatically set to 500 milliseconds.
