Nettest - Compaq ES40CSLP Installation, User & Service Manual

6.6.2.12 nettest

The nettest command tests the network ports using MOP loopback.
Nettest performs a network test. It can test the ei* or ew* ports in internal loopback, external
loopback, or live network loopback mode.
Nettest contains the basic options to run MOP loopback tests. It is assumed that this command
will be included in a script for most applications. Many environment variables can be set from
the console to customize nettest before nettest is started. The environment variables, a brief
description, and their default values are listed below.
_____________________________ Note____________________________
Each variable name is preceded by e*a0_ or e*b0_ to specify the desired port.
______________________________________________________________
You can change other network driver characteristics by modifying the port mode. See
the -mode option.
Use the kill command to terminate an individual diagnostic or the kill_diags command to
terminate all diagnostics. Use the show_status display to determine the process ID when
terminating an individual diagnostic test.
Syntax
nettest ( [-f <file>] [-mode <port_mode>] [-p <pass_count>]
[-sv <mop_version>] [-to <loop_time>] [-w <wait_time>]
[<port>] )
Arguments
<port>
Options
-f <file>
-mode <port_mode>
-p <pass_count>
Specifies the Ethernet port on which to run the test.
Specifies the file containing the list of network station addresses
to loop messages to. The default file name is lp_nodes_e*a0 for
port e*a0. The default file name is lp_nodes_e*b0 for port e*b0.
The files by default have their own station address.
Specifies the mode to set the port adapter (TGEC). The default is
ex (external loopback). Allowed values are:
df : default, use environment variable values
ex : external loopback
in : internal loopback
nm : normal mode
nf : normal filter
pr : promiscuous
mc : multicast
ip : internal loopback and promiscuous
fc : force collisions
nofc : do not force collisions
nc : do not change mode
Specifies the number of times to run the test. If 0, then run
forever. The default is 1.
NOTE: This is the number of passes for the diagnostic. Each
pass will send the number of loop messages as set by the
environment variable, eia*_loop_count or ewa*_loop_count.
