Can we use gigabitethernet link in portchannel for VSL for 6509 VSS instead of tengig links?
I have following hardware
Qty: 2 x Cisco 6509 chassis, each populated with:
1 x VS-C6509E-SUP2T - IP services and VSS
2 x WS-CAC-3000W - Power supplies
2 x WS-X6824-SFP-2T - fibre blade with GLC-SX-MM (fabric enabled DFC4)
1 x WS-X6848-TX-2T - copper 10/100/1000 blade (fabric enabled DFC4)
so in my 6509 I don't have any Tengige Module. and want to use both 6509 as VSS , so can I use Gige links to form the VSL instead of tengige ?

Hello,
Surely you can use the Gig Interfaces for the VSL Links, However, its not recommended. The reason behind having the 10Gig VSL uplink ports is for its impact on the Backblane Capacity and Forwarding rate.

Hi Mohamed,
VSL links must be 10Gig.
The VSL link is treated as a systems control link and encapsulates all traffic into a special system header called the Virtual Switch Header (VSH). This encapsulation is done via dedicated hardware resources and the VSL can only be configured on a 10-Gigabit interface with following hardware ports:
•Sup720-10G, 10-Gbps ports
•WS-X6708
•WS-X6716 (in performance mode only, requires 12.2(33)SXI)

Hi Reza,
As Sup 720 10G ports can be used as VSL link, so i assume same is true with the sup 2T 10 gige port.
also can i create VSS system by using 2 6509 with one SUP 2T on each of them instead of 2 SUP 2T on each chassis ?

Hi,
The only 2 sups that support VSS are Sup-720-VS and Sup-2T. On each Sup you can use the 10Gig links for VSL.
also can i create VSS system by using 2 6509 with one SUP 2T on each of them instead of 2 SUP 2T on each chassis ?
Yes, all you need is one Sup-2T in each 6500.

Hi Reza,
Although havent seen it done on non 10-Gig Ports, I assumed it should work for the Gig as well, but the documentation clearly stated only the SUP 10-Gig ports can be used for VSL. Thanks for correction (+5 rating).
