Mirroring 10G(SFP) to 1G

[strelok]

Hello !

Could you hint about mirroring 10G ports to 1G port ?

According to Network Configuration Guide:

### What Ports Can Be Mirrored ?
Mirroring between any 10/100/1000 port to any other 10/100/1000 port and between any SFP to any other SFP port is supported.

Does it mean that I can't to mirror 10G (SFP) port to 1G (Ethernet) port ?

You can mirror a 10G port to a 1G port, but you should not expect this to work fine whenever the bandwidth is above 1G.

Hello benny !

Thank you for response.

Yes, I understand that 10G will not match 1G. But there are not a lot of traffic yet.

By the way, Do you know adapters for 10G interface ?
I mean some 10G adapters for Laptop or maybe separate device for traffic mirroring such interfaces (10G) ?
I couldn't find devices or adapters for this aim

Most laptops will not be able to transport 10G through their "hot-plug" interfaces, hence you'll likely not find any adapters.

The solution would be a professional test equipment (Fluke, Wild Packets, ...) that could help you with that (but as it is professional equipment, it comes with a price).

If you have some server hardware around, you can probably use that with e.g. Debian Linux on it to do your analysis.

Ok, I see.

Thank you !

Always do the math..

Depening on Number of PCIe Lanes a 10Gig Card may only transport a certain amount of data.

10Gig Interface can transport over 1 Gigabyte/s of Data.. That needs to be stored, (a good SSD can write about 400MByte/s) and processed.

So without some really fast SSD-Raid and lots of RAM you may have troubles capturing more than a couple of seconds of a fully utilized 10G link.

But according to my experiences 10G links are hardly fully saturated (apart from backup servers) in most reallife scenarios..
