The link integrity test feature is a requirement of the IEEE 10Base-T standard. The purpose of the test feature is to enable a 10Base-T node to detect a link failure. The standard requires that on a periodic basis, each station on the net transmit link pulses whenever it is not transmitting valid packets. Sampling the link pulses, the receiver will assume that the network connection (link) is intact and assumes a link pass state. This is indicated as the link LED being on whenever such LEDs are provided.
The IEEE 10Base-T specification states that the link test feature should always be enabled at the host and hub. Complications may arise because:
Under either of the two conditions, the receiving station translates the lack of link pulses into a link failure, unless the receiving station is programmed to ignore the link pulses.
The SQEC card is equipped with this programming feature. The default state is for the SQEC card to check for link pulses. If the hub cannot be configured to send link pulses, the SQEC card can be programmed on a per channel basis to disable the link test, and thus ignore link pulses and assume link pass state. Four LEDs are provided, one for each channel. Once the cable to the hub is plugged in, the LEDs will light up green under the following conditions:
The LEDs will be off under the following condition:
Note - The SQEC card will transmit link pulses independent of the state of the link integrity test feature.
This section explains how to enable (default) or disable the link test for all
SQEC channels or for each channel individually.
When these commands are entered at the OpenBoot PROM prompt, they are
lost when the system is powered down. To execute these commands each time the
system is powered on, edit the NVRAMRC as shown in Section A.2.2.4,
"NVRAMRC patch," on page A-8.
The SQEC Prom provides a method set-tpe-test and a property no-tpe- test for the associated Ethernet nodes (qe node).
If n is non-zero, it will enable tpe-link-test and remove the property
no-tpe-test; if n is zero, it will disable tpe-link-test and add the
property no-tpe-test.
It is a property with null value. If it exists, it means tpe-link-test is
disabled; if it does not exist, it means tpe-link-test is enabled.
Enter the following code into NVRAMRC if tpe-link-test must be disabled on some Ethernet ports. Repeat the line of code, specifying the node, for each node that must be disabled:
------------------------------------------------------------------------------
false " <Ethernet-node1-pathname" " set-tpe-test" execute-device-method drop false " <Ethernet-node2-pathname" " set-tpe-test" execute-device-method drop false " <Ethernet-node3-pathname" " set-tpe-test" execute-device-method drop false " <Ethernet-node4-pathname" " set-tpe-test" execute-device-method drop ------------------------------------------------------------------------------
Enable/disable tpe-link-test status can be checked from the ok prompt.
----------------------------------
ok cd <Ethernet-node-pathname'> .attributes ----------------------------------
-------------------------------------------
ok " <Ethernet-node-pathname" select-dev true set-tpe-test -------------------------------------------
or
--------------------------------------------------------------------------------
ok true " <Ethernet-node-pathname" " set-tpe-test" execute-device-method drop --------------------------------------------------------------------------------
-------------------------------------------
ok " <Ethernet-node-pathname" select-dev false set-tpe-test -------------------------------------------
or
---------------------------------------------------------------------------------
ok false " <Ethernet-node-pathname" " set-tpe-test" execute-device-method drop ---------------------------------------------------------------------------------
Following are examples of lines that must be added to the NVRAMRC to automatically disable tpe-link-test each time the system is powered-on:

To patch NVRAMRC, use nvedit and nvstore commands. If you use the tip window for tty input/output, use Shell Tool to create the tip window.
If you use Command Tool to create the tip window, type
stty intr \^i
before you enter the tip command.
To edit NVRAMRC from the ok prompt:
The screen will display 0:indicating line 0.
(A symbol other than the colon ":" may follow the line number.)
A 1: will be displayed for line 1.
A 2:, indicating line 2, will be displayed.
