Flow Statistics Configuration
Configuring the Drop Latency Time
You can change the default latency time for a network, a specified VSAN in a network, or for the entire
switch.
To configure the network and the switch drop latency time, perform this task:
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.
This section includes the following topics:
• About Flow Statistics, page 1-15
• Counting Aggregated Flow Statistics, page 1-15
• Counting Individual Flow Statistics, page 1-15
Command Purpose
Step 1
switch# configuration terminal
switch(config)#
Enters configuration mode.
Step 2
switch(config)# fcdroplatency network
value
Configures network drop latency time for the
network. The valid range is 0 to 60000 msec. The
default is 2000 msec.
Note The network drop latency must be
computed as the sum of all switch latencies
of the longest path in the network.
switch(config)# fcdroplatency network
value vsan vsan-id
Configures network drop latency time for the
specified VSAN.
switch(config)# no fcdroplatency network
value
Removes the current fcdroplatecy network
configuration and reverts the switch to the factory
defaults.
