Bonding 10Gb and 1Gb ports

Hello,

I'd like to know if is possible bonding 10Gb and 1Gb ports.

The plan is to configure one 10Gb port and one 1Gb port from H3C 5500 to one 10Gb port and 1Gb port on HP 7510.

Regards,

Alex.

No, it's not possible to aggregate (Port Trunking/Port Bonding/Port Teaming/Link Aggregation/etc.) physical interfaces with dissimilar media speeds (10Gbps with 1Gbps or vice-versa). You can instead aggregate 1Gbps with other 1Gbps interafaces (up to 8 in a single aggregation group, generally) or 10Gbps with other 10Gbps interfaces, you can't do a mix.

You could use 2 10Gb ports, but use media converters on one of the links to reduce it to 1Gb.

:)

But seriously....whose idea was this?

Hi,

Yes, I know it seems quite strange, but my IT manager told me to do so. I advice him I though it was not possible to bond different types of speeds, but he insisted.

Because of this I decided to post this here.

Thanks a lot,

Hi,

With media converters, do you mean SPF transceivers?

I see I can use 1Gb SPF on 10Gb ports, and that would be the way to go.

Re: Bonding 10Gb and 1Gb ports

There is some confusion running on...

Using an SFP Transceiver on a SFP+ slot supporting SFP/SFP+ Transceivers is totally possible but this is unrelated with request done (as it was written): for Port Trunking you still must use all SFP or all SFP+ Transceivers...on both ends...not a mix.

No, I meant media converters, not transceivers. It was a joke. I was mocking your boss's completely terrible idea.

If you need both links up, make both links live independently of each other and then use spanning tree to block the 1Gb link.

Wondering why it's so usual to hear managers having terrible ideas...
