Displaying Latency Information

You can view the configured latency parameters by using the show fcdroplatency command:
switch# show fcdroplatency
switch latency value:500 milliseconds
global network latency value:2000 milliseconds
VSAN specific network latency settings
vsan 1 network latency:5000 milliseconds
vsan 2 network latency:2000 milliseconds
vsan 103 network latency:2000 milliseconds
vsan 460 network latency:500 milliseconds

Flow Statistics Configuration

Flow statistics count the ingress traffic in the aggregated statistics table. You can collect two kinds of statistics:
• Aggregated flow statistics to count the traffic for a VSAN.
• Flow statistics to count the traffic for a source and destination ID pair in a VSAN.

Flow Statistics

If you enable flow counters, you can enable a maximum of 1000 entries for aggregate flow and flow statistics.
Be sure to assign an unused flow index for each new flow. The number space for flow index is shared between
the aggregate flow statistics and the flow statistics.

Counting Aggregated Flow Statistics

You can count the aggregated flow statistics for a VSAN.
