Collapsed Backbone & Cat Express 500

Hi,

I have a collapsed backbone design with a single C3750G as a core switch and 6 Cat Express 500 switches as access switches.

Q1. Is it possible to cascade the 6 CE 500 access switches using their uplink ports ?

The first and the sixth access switch will have their uplinks to the core.

Q2. If I do a 802.1q trunk on all the cascade links, what are the spanning tree implications ? Which ones will block ? How do I get around this problem ?

Any advice is much appreciated.

Thanks,

Paul

Re: Collapsed Backbone & Cat Express 500

A collapsed backbone has high-bandwidth uplinks from all segments and subnetworks to a single device, such as a Gigabit switch, that serves as a single point for monitoring and controlling the network.
