Table 152: show interfaces (Gigabit Ethernet) Output Fields (continued)
Level of OutputField DescriptionField Name
detail extensive(10-Gigabit Ethernet interfaces) Displays Physical Coding Sublayer (PCS) fault
conditions from the WAN PHY or the LAN PHY device.
• Bit errors—Number of seconds during which at least one bit error rate (BER)
occurred while the PCS receiver is operating in normal mode.
• Errored blocks—Number of seconds when at least one errored block occurred
while the PCS receiver is operating in normal mode.
PCS statistics
detail extensiveShows the link degrade status of the physical link and the estimated bit error
rates (BERs). This field is available only for the PICs supporting the physical link
monitoring feature.
• Link Monitoring—Indicates if physical link degrade monitoring is enabled on
the interface.
• Enable—Indicates that link degrade monitoring has been enabled (using
the link-degrade-monitor statement) on the interface.
• Disable—Indicates that link degrade monitoring has not been enabled on
the interface. If link degrade monitoring has not been enabled, the output
does not show any related information, such as BER values and thresholds.
• Link Degrade Set Threshold—The BER threshold value at which the link is
considered degraded and a corrective action is triggered.
• Link DegradeClear Threshold—The BER threshold value at which the degraded
link is considered recovered and the corrective action applied to the interface
is reverted.
• Estimated BER—The estimated bit error rate.
• Link-degrade event—Shows link degrade event information.
• Seconds—Time (in seconds) elapsed after a link degrade event occurred.
• Count—The number of link degrade events recorded.
• State—Shows the link degrade status (example: Defect Active).
