EXEC Privilege

Version 9.3(0.0)

When you enter the "instance all" option, "show hardware stack-unit 0 buffer-stats-

snapshot unit 0 resource X" Output for all available instances on the history

collection is displayed.

When you enter the "instance id" option, "show hardware stack-unit 0 buffer-stats-

snapshot unit 0 resource X" for specified instance alone is displayed.

When you enter the "summary" option, "show hardware stack-unit 0 buffer-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 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.
