Extreme Networks ExtremeWare - Configure Sonet Threshold Signal Fail Ports

1670 ExtremeWare Software 7.3.0 Command Reference Guide
PoS Commands
configure sonet threshold signal fail ports
configure sonet threshold signal fail <error_rate> ports <portlist>
Description
Configures the signal failure threshold for the specified SONET ports.
Syntax Description
Default
The default is 10
-5
.
Usage Guidelines
A signal failure (SF) event is generated if the bit error rate (BER) for the SONET line exceeds the
configured threshold. A SF event brings the port down. If automatic protection switching (APS) is
enabled on the port, a SF event will initiate a line switch. The
error_rate parameter is an integer in the
range [3-5], where the SF BER is 10
-error_rate
. The default value of the error_rate parameter is 5, which
equates to a SF BER of 10
-5
, or 1 per hundred thousand.
Example
The following command example sets the signal fail threshold value to 3 for port 1 of the PoS module
installed in slot 8 of the BlackDiamond switch:
config sonet threshold signal fail 3 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 signal failure threshold for the SONET ports.
portlist Specifies the port number(s).
