Nexus 56128 connectivity with FEX 2348TX

[mosheroter]

hi all

i have nexus 56128 with all is QSFP port populated.

i need to connect my Nexus 2348TQ to the nexus 56128 via the SFP+ ports but i don't want at that point to wast 4x10G ports.

i want to use FET-40 on the 56128 side and only 1 FET-10 in the nexus 2348TQ side and the connectivity will be done by fiberoptic brakeout cable.

anyone knows if this configuration is available so i will be able to use breakout mode in the FEX side and connect it only through a 1x10G connectivity ?

thanks

Hi,

Yes, you can use the breakout cable for your 10Gig connectivity to FEX . The ports will not be wasted, as you can use the rest of the 10Gig ports for other FEXs or other devices with 10Gig ports.

thank you for your answer

do you know where i can find it documented because at the moment when we try it the ports are not sync.

Hi,

Have a look at table-1 in this link. 2348TQ does not appear to be supported with 5672 and 56128.

hi

the 56128 supported as a parent switch for the nexus 2348TQ,

the solution is work we found out that the fex was DOA

thanks
