Networking issue

Hai Guys

We have one Dell switch S4148T and its have four 100GBE and two  40 GBe  SFP+ port.  Same like we have one dell chassis M100E.  It have two dell force10 MXL 10/40 GBE balde switch. we connect the cable from S4148T to force10 MXL blade switch and do the initial configuration. But still swicth ports are down ( both 100GBe and 40 GBe) . Any one can help me to resolve this issue. Can you share the configuration with me

From what I have found is that you have 6 optical ports and 48 ethernet ports.

48 fixed 10GBase-T RJ-45 optical ports
• 2 fixed QSFP+ optical ports
• 4 fixed QSFP28 optical port

With optical ports you connect the TX to the RX and vice versa

Hai Sir

You are absolutely correct. We have 6 QSFP port  in Dell S4148T Switch. Same like we have 4 port in Dell Force10 MXL fabric card whicha was connected to Dell M100E chassis. We already purchased  QSFP+ to SFP+ 40GBE passive copper cable for connectivity. I already connect port using this cable( Dell S4148T to Force10 MXL). But I can see that interface is not up. At the same time we can ping A1 and A2 controller through chassis management. But its limited to   1GBP speed.Our motive we connect these switch using SFP+ cable .Then got 40GBP speed.

I think some manual configuration required in both switches.

Can you guide me. Because first time I am using this chassis.   Actually I am  sucked now . I need proper guidance for move to next stage
@David, I use copper DAC breakout cable to go from QSFP to SFP+ in my data center. It is standard and recommended practice as DAC cables are much less expensive than vendor supplied optics.

OP, have you contacted Dell EMC support?

If you want help here, you should start by posting configuration of the switch ports, the interface status of the ports, and any relevant information from the switch logs.

Hai Guys

I already do the some basic configuration. But still QSFP port are down.  I need your guidance
Again I ask that you post interface configuration, interface status, and output from show logging that includes any information about the interfaces in question.

Which interfaces do you have connected to each other? A quick scan of the configuration din't show anything like a description that says what a port is connected to.

bpduguard will disable the interface if it detects a switch on the other side.

Please output "show interface x/yy/zzz", which should give more detailed information than "show interface status".
