[c-nsp] duplex negotiation on a 6500

[Nicolaj Ottsen]

I think what you are looking for is "speed nonegotiate", as I understand
it, half-duplex on ge does not exist.

Subject: [c-nsp] duplex negotiation on a 6500


Question:  How do I turn off duplex negotiation on a 6500 running IOS
and set the duplex to nonnegotiated "full"?

I see that Cisco's advice is to allow auto-negotiation. But my ISP wants
duplex negotiation off. My question is, on the Sup720 with IOS, do I
have a choice on Gig-E GBIC ports? The commands that would work in other
situations (CatOS, GSR) simply don't seem to be there. And 'show int
status' looks like:

Gi2/4 HPR Sunnyvale (Com connected routed full 1000 1000BaseLH

Note that it says "full" rather than "a-full". That seems inconsistant
with the docs. The docs don't say that negotiation is required, but
neither do they say how to turn it off.

This is:

Version 12.2(17d)SXB1 ; the interface is WS-X6516A-GBIC

Thanks.
