[c-nsp] no negotiate auto

[Ivan]

I have some fibre connections (non Cisco remote endpoints - not yet sure 
of the brands) to an old WS-C4908G-L3 using GBICs that I would like to 
move on to a new Cisco 3750-G using SFPs.  I have been unable to get any 
links to come up on the new Cisco 3750.  The existing WS-C4908G-L3 
interface configuration uses "no negotiate auto" which as far as I can 
find allows compatibility with pre Gigiabit standard devices. 
(http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a00800a7af0.shtml#gig_aut_neg).  
The "no negotiate auto" command doesn't seem to be available on the 
3750.  Can some tell me if there a similar command for the 3750s or will 
the remote end need an upgrade or replacement?

Thanks

Ivan
