crc-monitor
Syntax crc-monitor
Context config>port>ethernet
Description This command enables the context to configure Ethernet CRC monitoring parameters.
sd-threshold
Syntax sd-threshold threshold [multiplier multiplier]
no sd-threshold
Context config>port>ethernet>crc-monitor
Description This command configures the error rate threshold at which the signal degrade condition is
declared on an Ethernet interface. The error rate threshold value is the ratio of errored frames
over total frames received, which is calculated as an average over the time set by the sliding
window. The value is calculated as M × 10E-N, where M is the optional multiplier used to
increase the error ratio, and N is the rate of errored frames allowed (threshold). For example,
3 × 10E-3 sets the error rate threshold at 3 errored frames per 1000 total frames received. If
no window-size is configured, a default of 10-s is used. The CRC errors on the interface are
sampled once per second.
The multiplier keyword is optional. If the multiplier keyword is omitted, the default value of 1
is used.
The no form of the command disables sd-threshold monitoring.
