Probe Protocol Configuration 

The Probe Protocol Configuration screen (#92) in figure 5-6 is displayed
when you press the [Go To PROBE] function at the Protocol Configuration
screen (figure 5-4).  It is also displayed when you type the path name:

@NETXPORT.NI.NIname.PROTOCOL.PROBE

in the command window of any screen and press the [Enter] key, where
NIname is a configured LAN NI.


          Figure 5-6.  Probe Protocol Configuration 

This screen allows you to configure the information required for the
probe protocol.  The probe protocol exists on an IEEE 802.3 LAN network
to provide a means of exchanging addressing and naming information
between nodes.  Press the [Save Data] function key to transfer the data
displayed on the screen to the configuration file you are creating or
updating.  Verify that the data record has been created by checking that
the Data flag is set to Y.

Fields 

Proxy enabled (Y/N)       Proxy nodes exist on LANs to provide node name
                          and address mapping facilities for nodes that
                          do not have local network directories.  Proxy
                          requests are multicast on the LAN to request
                          information about a third-party node from a
                          proxy node.

                          Y means this node may be a proxy server and to
                          answer all proxy requests on the LAN. N means
                          this node will ignore all proxy requests on the
                          LAN.

                          Default value:  N

                          Range:  Y or N

Probe requests            This is the maximum number of transmissions of
retransmission maximum    probe requests (name requests and address
                          requests) before a probe failure is reported.
                          Because it is unlikely that probe-request data
                          is lost, HP recommends that you keep the
                          maximum number of retransmissions low.

                          Default value:  2

                          Range:  1-10

Probe requests            This field is for specifying the time limit
retransmission timeout    between retransmissions of probe requests.
(seconds)                 This is the time interval in seconds that the
                          probe protocol will wait for a reply before
                          attempting to retransmit a request.  The value
                          should be set sufficiently large to avoid
                          retransmissions in a temporarily overloaded
                          environment, yet small enough to get a timely
                          failure report when failure is inevitable.

                          Default value:  1

                          Range:  1-10

Proxy requests            The maximum number of retransmissions of proxy
retransmission maximum    requests before a probe failure is reported.
                          Because it is unlikely that probe-request data
                          is lost, HP recommends that you keep the
                          maximum number of retransmissions low.

                          Default value:  2

                          Range:  1-10

Proxy requests            The time interval in seconds that the probe
retransmission timeout    protocol will wait for a reply before
(seconds)                 attempting to retransmit a proxy request.  The
                          value should be set sufficiently large to avoid
                          retransmissions in a temporarily overloaded
                          environment, yet small enough to get a timely
                          failure report when failure is inevitable.  The
                          default value is set somewhat higher than for
                          probe requests timeout because

                          proxy requests involve a network directory
                          lookup and consequently more time than regular
                          probe requests.

                          Default value:  4

                          Range:  1-10
