CXL - BXL

Hello,

I have 7600 with RSP720-CXL. If I put in linecard with BXL-DFC whole chassis will drop to BXL functionality.

But what is the difference? BXL and CXL has equal TCAM. What functionilty could I loose?

Regards,

A.

CXL - BXL

Hello Antonio,

the only reference I have found is the Q&A about PFC, DFC and CFC

http://www.cisco.com/en/US/products/hw/switches/ps708/products_qanda_item09186a00809a7673.shtml

I cannot find the respective datasheets of DFC 3BXL and DFC 3CXL for making the comparison that you are suggesting.

If I'm not wrong The C generation of DFC3 came out with VSS, so I would expect CXL to have the VSS features and the BXL to have not.

Q.   If the WS-X67xx line cards are required in Virtual Switching System   (VSS), is the DFC3C or DFC3CXL also required, or could the default CFC be   used?

A. There is no restriction from the VSS to use DFC3C / DFC3CXL. Similar to       normal switch requirements, either line cards with DFC3C/CXL can be used, or       only the CFC can be used.

Note that the 8-port 10G card (WS-X6708-10G-3C/XL) must have a DFC       installed for it to be operational.

Hope to help

Giuseppe
