    Fiber optic ports are not working after VLANs are created on the main switch

    Check for link status on switch ports; ensure they are up and not in a disabled or error state. Confirm that the VLAN configurations on both ends of the link match. There are no specific requirements for this document. This includes Doppler. Recently some of switches I have has been shown faulty issue on Fiber port. I have seen this kind of issue on both '3750X series and 2960X series', and issue is following: - Swithes are 48- Ethernet ports PoE + 4 Fiber ports - 3750X switch = 3/4 ports are currently plugged with Cisco GBIC module. VM connectivity is not working between VLANs, even though the VM network adapter (vNIC) shows no indication that it is disconnected. So to test this, i pushed out a new config to 2 switches, rebooted, and did a show config. In order to find and fix connectivity problems caused by Virtual Local Area Networks (VLANs), VLAN troubleshooting entails a methodical approach to examining the setup and condition of network devices. Given that VLAN issues can impede host connectivity and proper network operation, this ability is. I have a problem trying to update my 5320 switches and utilize 10gb SFP ports now that we dont have to pay for them.
