Flow Statistics Configuration

Command or Action
Step 3 switch(config)# fcdroplatency network value
vsan vsan-id
Step 4
switch(config)# no fcdroplatency network
value

Displaying Latency Information

You can view the configured latency parameters using the show fcdroplatency command, The following
example shows how to display network latency information:
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.

About 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

To count the aggregated flow statistics for a VSAN, perform this task:
SUMMARY STEPS
1. switch# configuration terminal
2. switch(config)# fcflow stats aggregated index value vsan vsan-id
3. switch(config)# no fcflow stats aggregated index value vsan vsan-id

Configuring Fibre Channel Routing Services and Protocols
Purpose
The network drop latency must be computed as the sum of
Note
all switch latencies of the longest path in the network.
Configures network drop latency time for the specified VSAN.
Removes the current fcdroplatecy network configuration and reverts
the switch to the factory defaults.
