thanks.

It seems that this is brocade specific, I've tested the OIDs on our Brocade 
switches and it returns values, but on a Q-Logic SANBox I get:
SNMPv2-SMI::enterprises.1588.2.1.1.1.6.2.1.3 = No Such Object available on 
this agent at this OID

:(
I don't like this vendorspecific things :(

But thanks, so we have at least some code for our Brocade switches.


Thanks,
