Description

Primary Server

Requests Sent: The total number of NTP requests the switch sent to the primary

 

NTP server to synchronize time.

 

Responses Received: The total number of NTP responses received from the

 

primary NTP server.

 

Updates: The total number of times the switch updated its time based on the NTP

 

responses received from the primary NTP server.

Secondary Server

Requests Sent: The total number of NTP requests the switch sent to the

 

secondary NTP server to synchronize time.

 

Responses Received: The total number of NTP responses received from the

 

secondary NTP server.

 

Updates: The total number of times the switch updated its time based on the NTP

 

responses received from the secondary NTP server.

Last update time

The time stamp showing the time when the switch was last updated.

Current system time

The switch system time when the command show ntp counters was

 

issued.

Uplink Failure Detection statistics

The following command allows you to display Uplink Failure Detection (UFD) statistics.

show ufd counters

Command mode: All

Uplink Failure Detection statistics:

Number of times LtM link failure: 1

Number of times LtM link in Blocking State: 0

Number of times LtD got auto disabled: 1

The following table describes the Uplink Failure Detection (UFD) statistics:

Statistics dump

The following command dumps the switch statistics:

show counters

Use the dump command to dump all switch statistics available (40K or more, depending on your configuration). This data can be used to tune or debug switch performance.

If you want to capture dump data to a file, set your communication software on your workstation to capture session data prior to issuing the dump commands.
