Interfaces
Default sdh
Parameters sdh — Specifies the values used on a G.781 Option 1 compliant network.
sonet — Specifies the values used on a G.781 Option 2 compliant network.
tx-dus
Syntax [no] tx-dus
Context config>port>ethernet>ssm
config>port>sonet-sdh
Description This command forces the QL value transmitted from the SSM channel of the SONET/SDH port or the Syn-
chronous Ethernet port to be set to QL-DUS/QL-DNU. This capability is provided to block the use of the
interface from the SR/ESS for timing purposes.
Default
no tx-dus
symbol-monitor
Syntax symbol-monitor
Context config>port>ethernet
Description
This command configures Ethernet Symbol Monitoring parameters. Support for symbol monitoring is hard-
ware dependent. An error message indicating that the port setting cannot be modified will be presented when
attempting to enable the feature or configure the individual parameters on unsupported hardware.
sd-threshold
Syntax sd-threshold threshold [multiplier multiplier]
no sd-threshold
Context config>port>ethernet>sym-mon
Description This command specifies the error rate at which to declare the Signal Degrade condition on an Ethernet inter-
face. The value represents M*10E-N a ratio of symbol errors over total symbols received over W seconds of
the sliding window. The symbol errors on the interface are sampled once per second. A default of 10 seconds
is used when there is no additional window-size configured. The multiplier keyword is optional. If the mul-
tiplier keyword is omitted or no sd-threshold is specified the multiplier will return to the default value of 1.
Default no sd-threshold
Parameters threshold — Specifies the rate of symbol errors.
