I have also changed the ports already. Nothing. But if I connect the line to another switch of type 2960X, both ports go online. If I use another 3750X, the port on the 3750X stays down, too. I
We''ve got a DGS-1210-28P set up with two VLANs one for trusted, one for guest. The trusted connection from upstream is coming over on fiber (with a copper failover) and the unit is
SOLVED. This is mental. There was a PLC connected to a fiber optic port on stack switch ONE that somehow managed to disrupt the functionality of the rx side of the optical controller on
Practical Examples and Considerations Media Converters: If you need to connect a fiber optic cable to a switch without a fiber optic port, you''ll need a media converter. This device converts
This document describes how to troubleshoot fiber optic interfaces by addressing some of the fiber optic module and cabling specifications.
The only way to make the port work was to physically pull the optic and reseat it, or use a magic command to simulate that. After doing an iOS update we haven''t had that issue any longer.
