You are right. We changed the cables on one end and now everything is working.<br />
Thanks,<br />

Hello,<br />
<br />
&nbsp;I came out with a little issue.<br />
&nbsp;I have a CISCO SF102-24 with MGBSX1 SFP<br />
&nbsp;and a CISCO Catalyst 2960x with GLC-SX-MMD SFP<br />
&nbsp;There is a 100m multimode fiber between them with 4 fiber cables , so I have two available connections if by any means one goes down.<br />
<br />
&nbsp; The problem is that I have no link between them, as the SF102-24 switch is unmanaged I can't do anything to it, but I am thinking that maybe on the 2960X there is an option that I must put in order for the link to go up.<br />
&nbsp; I have the latest firmware on the 2960x also. And the config looks like this:<br />
<br />
interface GigabitEthernet0/49<br />
!<br />
<br />
Thanks,<br />

Fiber Connectivity CISCO SF102-24 and 2960X

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.
