Copper Ethernet into Nexus 5548

Answered Question

User Badges:

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).


HTH,

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)

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

Ashok

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