Copper Ethernet into Nexus 5548

Hello...new to the nexus world. We have a server that we would like to use on our new Nexus 5548 however, it has only Copper ethernet. Does Cisco have a copper SFP for the 5548. I know that 6500's had a copper SFP but, I'm not sure if that would be compatable in the Nexus 5548 world.

Thanks,

Dan

Make sure you do a speed 1000 if the port is a 1gb ethernet link. Otherwise you'll see it as inactive or unknown module or something like that on the NX5K.

int ethX/X

speed 1000

Reza/Devavrat,

Similarly I want to connect Cisco 2811 router to NX5548UP. How should I proceed?

Thanks

Like I said in your other post, 2811 is only 10/100 and cannot connect to the 5548 directly (1000/10G only).

jerry is right, the NX5548UP won't scale down 100mbps. Try using a Cisco 2900 ISR or use a Nexus 2000 FEX'd to the 5K.

If budget is an issue, you can use a 2821, but you also need a media converter to convert from copper (2800) to fiber (Nexus)

No need. Use a GLC-T on the 5K (copper)

Yes, I like the idea of using GLC-T

No need. Use a GLC-T on the 5K (copper)

But the GLC-T on a Nexus 5k will NOT negotiate to 100 Mbps, will it?

If not, then one of the solution is for a HWIC-1GE-SFP on the 2811.

Leo,

GLC-T would work if the device is 2821 not 2811.

2821 comes with 2 10/100/1000 on board ports.

Hi Reza,

But Ashok has stated that he's got the 2811.

Hi Leo,

This is why I said it cannot be done. Ashok also have a strict requirement that he will not upgrade the 2811 to anything else. The only solution is use the FEX.

Hello All,

Following is the summary:

At Router 2811

One port Gigabit module: HWIC-1GE-SFP

Trans receiver : GLC-T – 1 QTY

At Nexus 5548

Trans receiver : GLC-T – 1 QTY

Above requirements will enable me to connect Cisco 2811 router to Nexus 5548 switch.

Please let me know you views.

Thanks

This will work.

No because the 2811 goes upto a 100mb and the 5548 can come down to 1Gb.

Hi Devavrat,

Ashok said he will put a HWIC-1GE-SFP, it will work.
