Good Day!
Stive, I plug in SFP without fiber, that's why we have this strings in log. When I plug in fiber - I recieve this message:
Feb 15 10:38:05 SW-02 chassism[1225]: link 0/1/0 SFP receive power low alarm cleared Feb 15 10:38:05 SW-02 chassism[1225]: link 0/1/0 SFP receive power low warning cleared
On physical layer everything work fine, and we have software problem. SFP slot must be switched to FE mode, but it not so.
The question is in how to switch SFP slot in FE mode I think.
