LOYTEC CEA-709 - Reseting the Switching Tables

L-Switch User Manual 32 LOYTEC
Version 6.0 LOYTEC electronics GmbH
If the port LED is flashing red a potential problem persists on the network segment
connected to this port. This state is referred to as overload conditions.
A port overload condition occurs if
 the average bandwidth utilization of this port was higher than 70% or
 the collisions rate was higher than 5% or
 more than 15% CRC errors have occurred on a port with a power-line transceiver
or more than 5% on a port with a transceiver other than power-line or
 the L-Switch XP was not able to process all available messages.
For a deeper analysis of the reason of the overload condition it is recommended to use a
protocol analyzer (e.g. LOYTEC’s LPA) or a similar tool. The exact reason of the overload
condition can also be determined with the LSD Tool (see Section 9).
5.5 Reseting the switching tables
If the L-Switch XP is in smart switch mode (see Section 4.1.1) or repeater mode (see
Section 4.1.2) the status button needs to be pressed for at least 20 seconds, in order to reset
the switching tables. Resetting the switching tables means:
 Clearing the group forwarding, the subnet/node forwarding and the router
domain table.
 Clearing the L-Switch XP status and statistic data.
 Resetting the L-Switch XP back to unconfigured state.
All this is done when the button is released. Afterwards a reset is performed to let the
changes take effect. Once the button is held down for more than 20 seconds all port LEDs
are switched to orange and stay orange until the button is released and the L-Switch XP is
reset. This indicates that the switching tables were reset.
Alternatively to holding down the status button the switching tables can be reset by
selecting the menu item “Reset to factory defaults” in the console menu (see Section 5.3.6).
Important: If the L-Switch XP is operated in smart switch mode (see Section 4.1.1) and is moved
from one location to another or if major changes to the configuration of the network are
made, it is recommended to reset the L-Switch XP configuration to factory defaults.
Important: Wait at least 30 seconds after power-up of the L-Switch XP before pressing the Status
Button to ensure that the L-Switch XP has booted properly!
Important: If the L-Switch XP is manually configured it is recommended to disable the option to
reset the L-Switch XP back to factory defaults via the status button to prevent users from
accidentally clearing the configuration! This can be done via the console using the
corresponding menu option in the CEA-709 router configuration submenu (see Section
5.3.5)!
