Version 9.3(0.0) Introduced on the S6000 platform.
Usage
Information 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.
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.
