configure sonet threshold signal degrade ports
ExtremeWare Software 7.3.0 Command Reference Guide 1669
configure sonet threshold signal degrade ports
configure sonet threshold signal degrade <error_rate> ports <portlist>
Description
Configures the signal degrade threshold for the specified SONET ports.
Syntax Description
Default
The default is 10
-6
.
Usage Guidelines
A signal degrade (SD) event is generated if the bit error rate (BER) for the SONET line exceeds the
configured threshold. If automatic protection switching (APS) is enabled on the port, a SD event will
initiate a line switch. The
error_rate
parameter is an integer in the range [5-9], where the SD BER is
10-
error_rate
. The default value of the
error_rate
parameter is 6, which equates to a SD BER of 10
-6
,
or 1 per million.
Example
The following command example sets the Signal Degrade threshold value to
8
for port 1 of the PoS
module installed in slot 8 of the BlackDiamond switch:
config sonet threshold signal degrade 8 ports 8:1
History
This command was first available in an ExtremeWare IP Technology Services Release based on
v6.1.5b20.
Platform Availability
This command is available on the BlackDiamond switch only.
error_rate Sets the threshold for the bit error rate for the SONET line.
portlist Specifies the port number(s).
