Hi All
I bought 4 N9396TX with N9K-M6PQ module that support 6 port 40 G with QSFP-40G-SR-BD
I want to change the speed of module port from 40 G to 10 G and insert the CVR-QSFP-10GSFP converter to pysical convert from 40 G to 10 G and install SFP+ SR and LR in the converter
so I follow the following steps:
1- after power up the NX SW, I installed the converter with SFP+ in both sidesand it worked and up without any additional configuration
2- then I tried to insert the QSFP 40 G beside the SFP+ 10 G and I tried to shut and no shut the 40 G interface to enable it but I found that the 10 G SFP+ shut down, so I removed the 40 G QSFP and reset all ports to defult using
#default interface ethernet 2/1-6
but still not worked and tried to use the CLI command under the used interface
#interface ethernet 2/1
#speed-group 10000
then an error message appeared "ERROR: Ethernet1/40: Configuration does not match the port capability"
but the show interface ethernet 2/1 shoed that the speed became 10G but the port still down
so I searched and found that I must disable auto negotiate using
#no negotiate auto
but the command also refused also
I Know that the module port can work all in 10 G or all in 40 G so I removed the 40 G QSFP
does the module need to be restarted ?
and any suggestion?
