On the ASR1001 I am unable to change the speed and duplex on a gig port when the sfp is a multimode fiber(sx) , need to change to 100 full,should the sfp on the ASR1001 be able to be set to 100 full.

[Leo Laohoo]

You can't and you won't. 

Cisco SFP can only support one speed.  

100BaseFx SFP has the part number of GLC-GE-100FX.

I read on cisco website that the  GLC-GE-100FX will only work on 5 port and 6 port spa...is that correct?

my 1002-f has a 4 port spa....

Incorrect.  I believe only in the 5- or 10 port SPA.

Hi Leo

I have an issue in my data center, could you please me help out.

I have Cisco ASR1006 router in my data center and a 100Mpbs WAN link (over OFC) is coming from my ISP to my premises. The issue is my ISP is having 100BaseFx module at its end and I am having 1000BaseFx modules in my router. How should I terminate the OFC on my router as 100BaseFx are 1000BaseFx are incompatible ? Please recommend any SFP which I could use at my end in order to terminate the OFC directly on my router.
