Prerequisite for vss

[donnie]

Hi all,

I like to configure vss for my 2x cisco 6509 switches. I was advised both switches must be connected by 10G GBICs for vss to work. VSS would not work if i connect both switches using 1G GBIC. Is this true? Pls advise. TIA

The VSL link must be connected using 10 Gbps.  The heartbeat link is connected using 1 Gbps.

Yes you need 10 Gig interface.
