Re: What is meant by fabric

First Cisco supervisors did not have a switch fabric :

Then the SUP720 came for the Catalyst 6500 series chassis increasing bandwidth from classic bus 32Gbps to S2/MSFC2+SFM-module = 256Gbps (dCEF256/CEF256) to finally (CEF720/dCEF720) and as last VS-S2T with 2Terabit per second forwarding performane.

The Supervisor engine 720 integrates a high-performance 720 Gbps crossbar switch fabric with a forwarding engine in a single module, delivering 40 Gbps of switching capacity per slot (enabling 4-port 10GE and 48-port 10/100/1000 density line cards).

Finally good reading:

"Fabric" normal refers to a cross-bar architecture between ports or channels.  Note - often multiple edge ports (i.e. ports you connect devices to) are connected to the same fabric port or channel.

The important feature of a "fabric" is, any pair of its (fabric) port or channel can send/receive from another port or channel without regard to what's happening between other ports or channels.
