I have finished the implementation of one 6880-X switch and six stacked pairs of 6800IAs connected to 6880-X (one C6800IA-48FPD and one C6800IA-48TD stacked together). The stacks are connected to 6880-X with 10GE SR SFPs. How can I see serial numbers of SFPs inserted in IAs? Show inventory raw and show idprom don't seem to show those S/N, only the ones inserted in the parent switch.
