2.2.4.1.1 SWITCH DIAGNOSE PORT
Syntax
SWITCH DIAGNOSE PORT
Description
This command executes the Time Domain Reflection test - that is used to determine
whether or not an Etherenet Cable connected to the port has a fault..
The results are whether or not there is an “open”, “short” or “good term”.for each pair.
It also prints the distance to the fault if the result is not “good term”. The accuracy is to
within approximately 10%.
Options
None.
Example
--> switch diagnose port lan6
Port 2 Tx: open [0ft] Rx: open [0ft]
2.2.4.1.2 SWITCH DISABLE AGEINGTIMER
Syntax
SWITCH DISABLE AGEINGTIMER
Description
This command stops the aging timer used by the look up engine to remove expired FDB
entries.
If the ageing timer is disabled the look up entries in the FDB are kept permanently until
the SWITCH ENABLE AGEINGTIMER command entered or the switch is reset.
To show the current switch status, use the SWITCH SHOW command.

2.2.4.1.3 SWITCH DISABLE LEARNING
Syntax
SWITCH DISABLE LEARNING
Description
This command stops the learning engine used to update the look up table when frame
are received from new
Source Addresses
.
To restore the learning process, use the SWITCH ENABLE LEARNING command.
To show the current switch status, use the SWITCH SHOW command.

2.2.4.1.4 SWITCH DISABLE LOOPDETECTION
Syntax
SWITCH DISABLE LOOPDETECTION
Description
This command stops the loop detection on the Ethernet ports. Special “ping” messages
used to detect loop are stopped.
Any port that was set to coax mode still remain configured in this mode forcing the port
speed to 10M Full Duplex.
To show the current port status, use the SWITCH SHOW command.
Example
switch disable loopdetection

2.2.4.1.5 SWITCH DISABLE PORT
Syntax
SWITCH DISABLE PORT <port-name> [FLOW JAMMING]
Description
This command disables the selected switch port, or disables a flow control mechanism
on the port.
If jamming is specified the jamming signal used for flow control on half duplex ports will
be disabled.
To show the current port status, use the SWITCH SHOW PORT command.

2.2.4.1.8 SWITCH ENABLE LOOPDETECTION
Syntax
SWITCH ENABLE LOOPDETECTION
Description
This command turns on the loop detection feature on the switch. The Residential Gate-
way will start sending special “ping” messages to all the switch ports configured as
“coax”.
All the switch ports having a speed valued different from “coax” will not be involved in
the loop detection process.
To add an Ethernet port to the list of ports where loop detection is controlled, use the
SWITCH
SET

COAX
command.
Example
switch enable loopdetection
