VSS on cisco 4507R+E with sup8-E

Question

Hi folks,
I need to configure VSS on cisco 4507R+E switch with SUP8-E,but the problem is that as per the latest relase notes VSS is not supported on sup8-E. 
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/release/note/OL_32143-01.html
Can someone advise me how to proceed?

Hi,
The links coming from cpe1 and cpe2 can be bundled and made layer3 port channel on VSS swirtch?
No, the link can't be in a Porchannel as cpe-1 cpe-2 are 2 different devices. If cpe-1 and 2 were for example Cisco 3750 stacked, then yes, you could put both links in a Portchannel on the 3750s and also on 4500 (VSS).
on VSS switch : 172.16.10.6/29 (port channel)
cpe1: 172.16.10.2/29
cpe2: 172.16.10.3/29
HSRP virtual IP: 172.16.10.4/29
All above statements are correct.
Can you eloborate how I can use dot1q encapsulation for this scenario?
Let assume cpe-1 and cpe-2 are Cisco 3845 routers. In this case, you can simply create a sub-interface an each device connecting to the VSS with dot1.q
for example on cpe-1
interface gi0/0
interface gi0/0.10
ip address 172.16.10.2/29
encapsulation dot1q 10
the same thing on cpe-2 except a different IP address.
Now you create vlan 10 with dot1q encapsulation on the 4500 and add it to what ever interfaces that are connecting to the cpes with an ip address on th svi.
or you can keep the 4500 (vss) as layer-2 with no IP and no svi.
it that more clear now?
