The Probe Protocol Configuration screen (#92) in Figure 10-6 “Probe Protocol Configuration Screen” is displayed when you
press the [Go To PROBE] function at the Protocol
Configuration screen (Figure 10-4 “Protocol Configuration Screen”).
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 VG100LAN
NI.

This screen allows you to configure the information required
for the probe protocol. The probe protocol exists on a 100VG-AnyLAN
network using the IEEE 802.3 protocol 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 networks to provide node name
and address mapping facilities for nodes that do not have local
network directories. Proxy requests are multicast on the network
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 network.
N means this node will ignore all
proxy requests on the network.
Default value: N
Range: Y or N
- Probe requests retransmission maximum
This is the maximum number of transmissions of 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 retransmission timeout (seconds)
This field is for specifying the time limit between
retransmissions of probe requests. 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 retransmission maximum
The maximum number of retransmissions of proxy 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 retransmission timeout (seconds)
The time interval in seconds that the probe protocol
will wait for a reply before 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
