How to clear stats in mcData switch?

Thanks for the prompt reply. I have that doc.  clearStats comand is not working for me.

These commands worked.

Root> perf clearStats

Root> perf clearStats all

Root> clearStats 17

Clear fcns statistics

To clear the name server statistics, use the clear fcns statistics command in EXEC mode.

clear fcns statistics vsan vsan-id

Examples

The following example shows how to clear the name server statistics:

switch# show fcns statistics

Name server statistics for vsan 1

===================================

registration requests received = 0

deregistration requests received = 0

queries received = 23

queries sent = 27

reject responses sent = 23

RSCNs received = 0

RSCNs sent = 0

switch# clear fcns statistics vsan 1

switch# show fcns statistics

Name server statistics for vsan 1

===================================

registration requests received = 0

deregistration requests received = 0

queries received = 0

queries sent = 0

reject responses sent = 0

RSCNs received = 0

RSCNs sent = 0

To clear the Fabric Shortest Path First statistics, use the clear fspf counters command in EXEC mode.

clear fspf counters vsan vsan-id [interface type]

Examples

The following example clears the FSPF t statistics on VSAN 1:

switch# clear fspf counters vsan 1

The following example clears FSPF statistics specific to the Fibre Channel interface in VSAN 1, Slot 9 Port 32:

switch# clear fspf counters vsan 1 interface fc 9/32

For Mcdata it should be:

clearStats

Ramon,

OP is asking about McData not an MDS
