Table 93. Cable Test information
Field Description
Cable Status Indicates the cable status:
Cable Length The estimated length of the cable in meters. The length is displayed as a range
between the shortest estimated length and the longest estimated length.
Unknown is displayed if the cable length could not be determined. The cable
length is displayed only if the cable status is Normal.
Failure Location The estimated distance in meters from the end of the cable to the failure
location.
The failure location is displayed only if the cable status is Open or
Short.
Configure and view the logs
The switch generates messages in response to events, faults, or errors occurring on the
platform as well as changes in configuration or other occurrences. These messages are
stored locally and can be forwarded to one or more centralized points of collection for
monitoring purposes or long-term archival storage. Local and remote configuration of the
logging capability includes filtering of messages logged or forwarded based on severity and
generating component.
Manage and view the memory log
The memory log stores messages in memory based upon the settings for message
component and severity. You can set the administrative status and behavior of logs in the
system buffer. These log messages are cleared when the switch reboots.
For the message log, only the latest 200 entries are displayed on the page.
