6900 3*40g Expansion Module experiences?

[devnull]

Has anyone experiences with the 40Gig modules for the 6900?

Is it possible to have the vfl (bandwidth) using this modules?

Any real world experiences (stability/SFP Quality ...?

Yes, the VFL connection can run on 40G - however you shouldn't mix different speeds for VFL connections.

old thread but good question...

i saw today a video on youtube from alcatel...

How to configure an OmniSwitch 6900 from Standalone to Virtual Chassis mode

at minute 10:04 you see all vf-links list with different speed types?! Thats surprises me..

[devnull]

You can (in a VC of more than 2 Switches) mix speeds, but inside one VFL (the link between two switches) all the speeds must be the same.

So in a VC of 3 switches:
Ch1: VF-link1 (to CH2) 2*40G
Ch1: VF-link2 (to CH3) 2*10G

perfectly fine. not ok would be
Ch1: VF-link1 (to CH2) 1*40G and 1*10G

Thank you for the explanation.

Hi all,
we have 11 OS6900 VCs running, VF links are using 40G Ports on OS-HNI-U6 or OS-QNI-U3. The switches were setting up about 18 months ago and we have no problems with the VFs. We are using DACs with a length up to 5m.

Best regards
