I have a pair of 3064PQ with four 40gb ports. I want to connect them with a twinax qsfp cable.
Problem is, 40gbs ports appears has 4x10gb.
Eth1/51/1 -- notconnec 1 full 10G QSFP-40G-CR4
Eth1/51/2 -- notconnec 1 full 10G QSFP-40G-CR4
Eth1/51/3 -- notconnec 1 full 10G QSFP-40G-CR4
Eth1/51/4 -- notconnec 1 full 10G QSFP-40G-CR4
Is there a way to make Eth1/51 as a SINGLE 40gb connection instead of 4x10gb ?
In the past I have done it on 5600 series and I'm pretty sure they appeared as a single port. BTW, both ends of the twinax cable are a single QSFP connector (no 4x10gb split).
thanks. It seems this command change all qfsp ports ?
Problem is, this N3K has four qsfp ports but I need the first two ports to be 4x10gb and the last two ports 1x40gb.
I suppose it's not possible ?
atswcis1(config)# hardware profile portmode ?
48x10g+4x40g 48x10G+4x40G port mode
52x10g+3x40g 52x10G+3x40G port mode
56x10g+2x40g 56x10G+2x40G port mode
60x10g+1x40g 60x10G+1x40G port mode
64x10g 64x10G port mode
I just saw someone has type the command hardware profile portmode 64x10.
So I supposed they all act as 10gb right now...
I am not sure if there is way to convert 2 out 4 qsfp uplinks from 10 to 40 but there should be a way to convert all 4 of them.
Did you get an answer from TAC? I know in older versions of code it wasn't possible to breakout only 2 of the 4 40gig ports, but i'm wondering if newer versions of code allow it.
I've found intresring doc
Note that even though the command help gives the option to breakout the ports individually, this won't actually work. The options that work are 48x10g+4x40g or 64x10g.
Int's interesting may be this issue is fixed in lastest NXOSes becuse 56x10g+2x40g 56x10G+2x40G port mode can be extreemlyuseful in my case.
