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:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Enables the aggregated flow counter.switch(config)# fcflow stats aggregated index
value vsan vsan-id
Step 2
Disables the aggregated flow counter.switch(config)# no fcflow stats aggregated index
value vsan vsan-id
Step 3
Counting Individual Flow Statistics
To count the flow statistics for a source and destination FC ID in a VSAN, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Enables the flow counter.
switch(config)# fcflow stats index value
dest-fcid source-fcid netmask vsan vsan-id
Step 2
The source ID and the destination ID
are specified in FC ID hex format (for
example, 0x123aff). The mask can be
one of 0xff0000 or 0xffffff.
Note
Disables the flow counter.switch(config)# no fcflow stats aggregated
index value vsan vsan-id
