Wireless Access

Hi,

Can anybody please confirm that 10G ports on 7210 are backward compatible to 1G?

What if we choose to put Aruba's 1G base-X SFP module to use on 10G ports, will it work?

Quick response would be appriciated.

Thank you.

Yes, dual speed.

10GBASE-X (SFP+) Ports

The 7200 is equipped with four 10GBASE-X (SFP+) ports. These port are labeled as 2, 3, 4, and 5. These
ports are intended for use with Aruba supported SFPs. SFPs are 10Gb hot-swappable, optical transceivers,
which convert serial electrical signals to external serial optical or electrical signals. The ports support dual
speed (1GbE or 10GbE) operation.

Thanks for the quick response.

Can you please share the source of this information?

Great support.

Thank you once again.

Kudo on its way :)

I'm confused on two things.

1. I recived an email recently saying:"We cannot negotiate it to 10/100/1000 port speed"

2. That's a followup to a question about "port speed", found in the GUI. On my 7220 you cannot select 10g as an option, only Auto/1000/100/10. That said, you are saying here that it can be one gig? I'm a bit confused at the moment.

3. When I install a 10 gig spf+ card, will I be seeing the lower port speeds? Will 10g pop up or will I need to leave it on auto?

When you use a GBIC, you cannot set the port speed.

It will automatically come up on the rated speed.  Only connect GBICs with the same speed.

When you configure an interface without a GBIC, you can attempt to set the speed.

I believe I understand, thanks.

Do i have to convert the Slot? I used a 1 GE SFP and on CLI the Interface is named GE0/0/0.

After changing the SFP to SFP+ Interface name still is GE. Interface has got link but i cannot get connection.

Any idea?
