Just another data point: SFP DOM works fine for the SFP ports in the Sup32-8GE. (Well, mostly fine - integration of the transceiver monitors into the SNMP MIB tables entPhysicalTable and entSensorValueTable fails to happen at boot time, you have to unplug/replug SFPs to make that work. Tried under 12.2(18)SXF6 and 12.2(33)SRA.) -- Simon.
