Changing ARP Parameters

When you use guided configuration to update the LAN NI for Ethernet support, default parameters are set for the address resolution protocol (ARP) configuration.

To verify what these are, or to change them, do the following:

Obtain the configured LAN NI name (issue a NETCONTROL STATUS command).
Run NMMGR.PUB.SYS.
At the Open Configuration/Directory File screen, ensure that the configuration file NMCONFIG.PUB.SYS appears as the configuration file name. You want to open the file by pressing the [Open Config] key
The HP Configuration screen is displayed. At the Command prompt, enter the direct path name as follows and then press the [Enter] key:
@NETXPORT.NI.niname.PROTOCOL.ARP
where niname is the configured LAN NI name. The Address Resolution Protocol (ARP) Configuration screen is displayed. The ARP parameters are:
- Retransmission Maximum: The maximum number of times an ARP request will be sent if no reply arrives.
  Range: 1 to 10
  Default: 2
- Retransmission Timeout: The time (in seconds) between retransmissions of ARP requests if no reply has arrived.
  Range: 1 to 10
  Default: 1
If you change any parameters, press the [Save Data] key. Next,
1. Hold down the [Shift] key and press the [Tab] key which returns you to the command prompt.
2. At the command prompt, enter: validate, then press the [Enter] key.
3. The Validate screen is displayed. Press the [Validate Netxport] key to validate the updated configuration.
To exit the NMMGR program, hold down the [Shift] key and press the [Tab] key which returns you to the command prompt. At the command prompt, enter: EXIT, then press the [Enter] key.
If you changed any of the parameters, you need to restart the network in order to activate the changed configuration file as described later in this chapter under the heading, "Restarting the Network."
