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, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# fcdroplatency network 5000
switch(config)# fcdroplatency network 6000
vsan 3
switch(config)# no fcdroplatency network
4500
Step 3
switch(config)# fcdroplatency switch 4000
switch(config)# no fcdroplatency switch
4500

Displaying Latency Information

You can view the configured latency parameters using the show fcdroplatency command (see
Example

Purpose
Enters configuration mode.
Configures network drop latency time to be 5000
msec for the network. The valid range is 0 to 60000
msec. The default is 2000 msec.
The network drop latency must be
Note
computed as the sum of all switch latencies
of the longest path in the network.
Configures network drop latency time to be 6000
msec for VSAN 3.
Removes the current fcdroplatecy network
configuration (4500) and reverts the switch to the
factory defaults.
Configures switch drop latency time to be 4000
msec for the switch. The valid range is 0 to 60000
msec. The default is 500 msec.
The switch drop latency parameter should
Note
have the same value in all the switches in
the network.
Removes the current fcdroplatecy switch
configuration (4500) and reverts the switch to the
factory defaults.
