Classic and fabric-only line cards within the same Cat 6500 chassis

[ovt]

Can classic Cat 6500 line cards interoperate with fabric-only line cards (such as WS-X6516-GBIC or DFC3-equipped 67 series cards)?

Classic line cards connect to the shared bus only and the WS-X6516-GBIC or DFC3-equipped 67 series cards connect to the crossbar only. So, I wondering how packets can go between them...

Thx.

Read thru this and it will give you a good idea on how things are switched . http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_guide_chapter09186a0080160a5e.html#wp1051977

Thx. This answers my question. (BTW I meant 6816-GBIC fabric-only card in the prev. post.)

If the egress port is on a different nonfabric-enabled module, the DFC3 sends the packet to the Supervisor Engine 720. The Supervisor Engine 720 fabric interface transfers the packet to the 32-Gbps switching bus where it is received by the egress module and is sent out the egress port.
