SET PORT MODE DIAGNOSTICS

SET PORT MODE
DIAGNOSTICS
Use the SET PORT MODE REMOTE_DIAGNOSTICS/NON_REMOTE_DIAGNOSTICS
command to establish remote diagnostics on a port. Remote diagnostics allow
the port to detect failures on both its transmits and receive wire pairs. Use this
command when you are connecting two ports on 10BASE-T and 100BASE-T
modules to a Fault-Tolerant 10BASE-T Transceiver Module
(Model Number 5102T-TPFT) or establishing remote diagnostics on
CoreBuilder 5000 24-Port, 20-Port, 40-Port, and 36-Port Modules and the
EtherFlex Module.
This command is most useful when you also have redundant ports set up to the
transceiver. When you establish remote diagnostics and redundancy between
two ports:
1
The first port becomes the primary link while the second port becomes the
backup or redundant link.
2
If the primary link fails, the redundant link is activated automatically, thereby
preventing a network failure.
The cross-module redundancy feature enables you to set ports in different
modules as redundant pairs. For example, you can use a port in one 10BASE-T
module as a primary link and a 10BASE-T port in another module as the backup
link.
You must have link integrity enabled on both ports on the transceiver and on
both ports on the module for this command to work correctly.
Format
Example
The following command establishes remote diagnostics on port 5 in slot 16:
CB5000> set port 16.5 mode remote_diagnostics
Port 16.05 REMOTE DIAGNOSTICS ENABLED.

non_remote_diagnostics
Remote diagnostics disabled. Use this mode when there is not a
remote diagnostics-capable device at the far end of the
connection

Remote diagnostics enabled. Use this option when there is a
remote diagnostics-capable device at the other end of the
connection.
