When you enter the instance id option, show hardware stack-unit

 

stack-unit-numberbuffer-stats-snapshot unit 0 resource X for

 

specified instance alone is displayed.

 

 

 

When you enter the summaryoption, show hardware stack-unit stack-

 

unit-numberbuffer-stats-snapshot unit 0 resource X will be

 

enhanced to display the total buffered cells, shared cells, headroom cells for last 5

 

instances in the table format.

 

 

 

 

If information for specified instance id is not available when you enter the show

 

command, which occurs if you issue the command before the time elapsed for the

 

snapshot to be captured for that instance ID, the following informational message

 

is displayed on the console:%Info: Data for instance id id is not

 

available.

 

 

 

 

 

If information for specified instance id id is not available when you enter the show

 

command, which occurs if you issue the command before the time elapsed for the

 

snapshot to be captured for that instance ID, the following informational message

 

is displayed on the console:%Info: Data for instance id id is not

 

available.

 

 

 

 

 

For example, if you configured 5 as the maximum instances with linear periodicity

 

and a polling interval of 10 seconds, 1 as the multiplier, then 5 instances will be

 

polled at 10, 20, 30, 40, and 50 seconds incrementally. If you attempt to enter the

 

show command to display the fifth instance after 30 seconds of enabling polling,

 

the aforementioned information message is shown.

 

 

If specified instance ID is higher than the size of the maximum number of snapshot

 

instances configured, the following error message is displayed on the console:

 

%Error: Instance Id is not valid. Configured max snapshot

 

instances are <max-instances>

 

 

If you configured the maximum number of instances as 5 and attempt to view the

 

buffer statistics tracking details for the instance ID of 6, the aforementioned error is

 

shown.
