Greetings all. Concerning the WS-X4640-CSFP-E module, I was surprised to realize when I got it that the ports are numbered 1-80 rather than 1-40. Then I saw it is actually an 80 port blade when you use half-SFP's. But we have full SFP's, so how does it do the numbering? If I use all full-SFP modules, do the even-numbered ports just go unconfigured?
I'll reply to my own question, now that I found the answer the "manual" way. Yes, if you use full-size SFP modules, it only activates the odd-numbered ports. Here is a snippet of "show interface status" :
Gi5/1 notconnect 1 full auto 1000BaseSX Gi5/2 inactive 1 full auto No Gbic
Gi5/3 notconnect 1 full auto 1000BaseSX Gi5/4 inactive 1 full auto No Gbic
