Hi All,

We have a presales case, where the partner is asking the difference between VS-S720-10G-3C and the WS-X6704-10GE linecard . He is asking from the perspective of the performance and features comparison.

I would appreciate any information that anyone would be able to provide. Thanks for the help in advance.

Awaiting your reply,

The following paper outlines deployment scenarios for the two cards if using them for Virtual Switch Links.


Brief excerpt:

“VSL-capable interfaces are required to create a VSL port channel. The current modules that support the formation of a VSL port channel are the 10 Gigabit Ethernet uplink ports on the Supervisor Engine 720-10G VSS (VS-S720-10G-3C/XL) and the Cisco 8-Port 10 Gigabit Ethernet Switching Module (WS-X6708-10G-3C/XL). (Refer to Figure 5.)

Figure 5. VSL-capable Modules

These interfaces contain new port ASICs that allow the VSH to be encapsulated on each frame forwarded out of the port and also support the ability to de-encapsulate VSH-tagged frames.”

It is a start...
