The Probe Protocol Configuration screen (#92) in Figure 5-6 “Probe Protocol Configuration Screen” is displayed when you press the [Go To PROBE] function at the Protocol Configuration screen (Figure 5-4 “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
LAN NI.
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 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
