Switch information Nortel Networks Layer 2-3 GBE Switch Module(Copper)

Hi I am trying to get the switch information of an IBM Bladecenter. The switch modules are Nortel Networks Layer 2-3 GBE Switch Module(Copper). OID is 1.3.6.1.4.1.1872.1.18.1 Is there any way to make the data acquisition of this type of switch? In the "IP Device Info" i saw 0 ports an the cricket have no data. There is some workaround for this type of switch? Best Regards
