N9K-C93108TC-FX3P 1G Fibre in the QSFP28 ports

[j.a.m.e.s]

Could anyone tell me if I would be able to connect a 1G GLC-SX-MMD in Eth1/49-52 for the N9K-C93108TC-FX3P please? I know the QSA is required (CVR-QSFP-SFP10G) to assist with this kind of speed drop.

According to the transceiver matrix this should be OK, but I would like to check because the newer N9K-C93108TC-FX3 model does not support drop-down to 1G per the nxos10.4 release notes.

I have heard back from our Datacentre SE. The release notes are correct and Cisco has no plans to introduce 1G support on the N9K-C93108TC-FX3 ports Eth1/49-54 via the QSA. So if you have for example a 1Gbit carrier fibre, then it's best to purchase a N9K-C93108TC-FX3P model instead.

Note:      N9K-C93108TC-FX3 does not support 1G on QSA/QSA28 adaptor
