Nexus 9332PQ with FEX 2348UPQ

[Xavillon]

Hello,

I try to connect a parent 9332PQ with a FEX 2348UPQ.

The configuration is the following:

interface port-channel125
description FEX125
switchport
switchport mode fex-fabric
fex associate 125
vpc 125

!

interface Ethernet1/3
description FEX125
switchport
switchport mode fex-fabric
fex associate 125
channel-group 125
no shutdown

I used QSFP-H40G-CU1M between them.

I can see the led from N2K green but on N9K there is no activity and it is in not connect?

Do you known why  I can't see the FEX?

Thank you.

M.

Don't put the switchport mode fex under the interface only the port-channel as the example below...

interface ethernet 1/28
switch(config-if)# channel-group 4
switch(config-if)# no shutdown
switch(config-if)# exit
switch(config)# interface ethernet 1/29
switch(config-if)# channel-group 4
switch(config-if)# no shutdown
switch(config-if)# exit
switch(config)# interface ethernet 1/30
switch(config-if)# channel-group 4
switch(config-if)# no shutdown
switch(config-if)# exit
switch(config)# interface ethernet 1/31
switch(config-if)# channel-group 4
switch(config-if)# no shutdown
switch(config-if)# exit
switch(config)# interface port-channel 4
switch(config-if)# switchport
switch(config-if)# switchport mode fex-fabric
switch(config-if)# fex associate 101
