how many catalyst 4500Xs can be stacked to gather?

[Omid Almasieh]

Hi folks ,

I'm designing a hierarchical 3 layer campus network with different switch blocks .We need 10Giga Ethernet in the core to distributions and access layer , I was thinking about using a pair of catalyst 4509E in each block.after that I got interested in 4500Xs , in comparison with 4509Es they are much thinner and saves more room in rack space .I wanna use 4500X in my distribution layer .

The question is , as you know 4500Xs have 40 10Giga Ethernet ports , in some of my switch blocks I have more than 40 access switches (40 uplikns to distribution ) i wanna know how many of 4500Xs can i stack together ?

Two units in a VSS.

Hello, the 4500X is stackable but not in the true sense as the 3750's etc...
With the 4500X's you can enable VSS which is a type of stacking/ HA technology with up to 2 chassis in a stack as stated in the data sheet here:

Hope this helps

As the other posters have noted, VSS is limited to a single pair.  So your options are to have more than one pair of 4500X distribution pairs when you need more than 40 10g links, or use 6500s as your VSS pair, such as a pair of 6506s.

Thank you guys ...

Thanks for rating our useful posts, Omid.

FYI:  There's going to be a major announcement in regards to the Catalyst switches (possibly on or before Cisco Live San Diego).
