I currently have my lan connecting by trunk fiber on port 28 on the cisco 2970. Then I have 3 2950 switches connected to the 2970 with vlan 6. I configured switches all to access vlan 6 which is the only vlan used on the connected workstations. My problem is I keep getting %lineproto - 5 - updown or %lineproto - 3- updown messages, below is the config for both the cisco 2970 and 2950:
Please let me know what i'm doing wrong, again I only need to use vlan 6 on the workstations connected to the 2950 but looks like native vlan is 1, would that cause the updown which seem to be random? How can I troubleshoot?
Again it's LAN -(Dlink L3 Switch) by- fiber --> Cisco 2970 --> Cisco 2950 --> workstations
