Hi there.
I have a silly question: Does the 4500 support VSS (Virtual Switching System) ? On the official product overview page it says:
1.6 Terabits capacity with Virtual Switching System (hardware-ready)
What means Hardware ready ? Does it mean that it supports VSS in the same manner as the 6500 ?
The reason I'm asking this question is that I didn't find any info on the Internet about this.
We would like to upgrade our network by interconnecting the 2 sites with Layer 2 redundant links (Layer 2 extension), but I'd like to use the both links in a load-balancing manner, which can be a real pain in the ass with STP. The choice is between 4500 and 3750 stackable core switches. The 6500s are very expensive.
So I'd like to know whether we could implement VSS with these platforms
Thanks in advance

"Hardware ready" means it's waiting for an IOS version to enable it.
The 4500-X will eventually support VSS (see http://www.cisco.com/en/US/prod/collateral/switches/ps10902/ps12332/white_paper_c11-696802.html.)
I can't recall what's been publicly announced regarding other 4500s and VSS.

Hi,
For the 3750s, you can stack them. When stacked, they are similar to 6500 with VSS.
As for the 4500 series, you just have to wait a little longer. I have heard VSS is coming, but no firm date yet.

Hello Joseph,
Thank you for your response.
Do you know any other ways of load balancing traffic and avoiding loops in a Layer 2 environment using 4500s or 3750s switches ?

Reza, already mentioned 3750 stacking, but until there's VSS for the 4500, your other redundancy option is the 45xxR chassis with a 2nd sup. Less expensive than a 2nd chassis, although you only have one chassis of ports to work with instead of two chassis and you don't have chassis redundancy.

Hi Reza,
That's a great idea. Thanks for the reply

The 4500X is the based around the Sup7E supervisor card. The 4500X supports VSS. The Sup7E (not sure about the Sup7LE) will support VSS by mid-2012.
