10G fiber cable instead of VSS Cable

Hello Friends

i have two WS-C6506E chassis with  two VS-S720-10G-3C modules

and for physical connectivity i have two 10G fiber optic cables to each other

one is single mode and the other is multi mode fiber cable with 10 gig speed

my question is how i can configure both Sup engines if i want to configure VSL link between them

Or can i configure VSL betweem then in this envoirment or no ???

OR i need to configure a simple trunk links on both side Or HSRP for redundancy??

please advice me how i can configure both of the sup engine for this link between them.

thanks you for coopration in advance

Re: 10G fiber cable instead of VSS Cable


Creating a VSL link should not be a problem in this case. As far as your interfaces are up, you should be able to create a VSL link. Once VSS configured there is no need for HSRP as VSS switch from the L3 perspective will be a single control plane.

Hope this helps.

Re: 10G fiber cable instead of VSS Cable

For VSL links, you can use a combination of Multi-mode or single mode, but of course the prefer method is to use the same optics for all 4 interfaces.

here is link to start your VSS config:

BTW, there is no such thing called VSS cable...
