Configuring QSFP ports of Dell EMC 4128T-ON switches
Dear All,
We have a Dell EMC 4128T-ON switches. We are using QSFP to 4LC cable. We want to use only 1 LC connector to connect the Dell switch to the core switch and rest of the LC connector are not connected to anything.
Really appreciate if some one can let us know how to configure the port to achieve this i.e. we want to connect QSFP end of the cable to Dell switch and 1 LC connector to core switch. we want to use this set up as a normal link with QSFP and 1 LC.
Thank You,
Gayan

Hi, we don't give configuration support you can contact the deployment service for that. But I've researched and found some things as below. Please take a look:
Dell EMC Networking S4148-ON and S4128-ON
Dell EMC Networking S4248-ON Switch Configuration Guide for Dell EMC Unity SC Series and Dell PS Series iSCSI SANs
Dell Networking S3048-ON Switch Configuration Guide for Dell PS Series SANs (https://dell.to/3WL1mAS)
I believe it could be like that. to configure the QSFP ports of 4128T-ON switches, you can try to use below steps
Connect the QSFP end of the cable to the Dell switch and 1 LC connector to the core switch.
Configure the QSFP port as a 40G port.
Configure the LC port as a 10G port.
Here is an example configuration for a QSFP port:
interface fortyGigE 1/1/1
no shutdown
speed forced 40gfull
channel-group 1 mode active
exit
Here is an example configuration for an LC port:
interface tenGigE 1/1/2
no shutdown
speed forced 10gfull
channel-group 1 mode active
exit
