    Having issue with configuring vlan 1 on 1550-24 after upgrading to R13-5-2

    alwaysdead New Member

      When trying to configure the units IP address I get this overlap and the vlan stays at 0.0.0.0

      this is on a clean AOS install.

       

      I can access the switch via CLI however without being able to set vlan 1 I cannot access the GUI.

      any help is greatly appreciated.

      Thanks

       

       

      enable

      Password:

      Switch#config terminal

      Switch(config)#interface vlan 1

      Switch(config-intf-vlan 1)#ip address 10.10.10.1 255.255.255.0

      %10.10.10.0 overlaps with vlan 1

          The default configuration of the 1550 series switch is -

           

           

          !

          interface vlan 1

            ip address dhcp

            ip address  10.10.10.1  255.255.255.0  secondary

            ip route-cache express

            no shutdown

          !

           

          Therefore setting an IP address in another subnet will bring up the interface and the secondary IP address of 10.10.10.1 /24.

          ** Beware that leaving this secondary IP address on all switches can cause IP conflicts.

           

          See Re: I have 3 adtran netvanta 1550 switches.  for an example.

            By default it has a secondary IP of 10.10.10.1/24 configured, with primary DHCP. If you have console access you can just delete the secondary and reassign the primary. If you're accessing over the network, temporarily assign a primary IP address in a different subnet, then delete the secondary, then re-assign the primary.

             

            interface vlan 1

              ip address 10.10.11.1 255.255.255.0

              no ip address  10.10.10.1  255.255.255.0  secondary

             

            You will lose connectivity. Then re-connect to 10.10.11.1 - you'll need to change the IP of your computer temporarily to something like 10.10.11.2 .

             

            Then:

             

            interface vlan 1

              ip address 10.10.10.1 255.255.255.0

             

            Then move your computer back to 10.10.10.x and reconnect again, then write memory.
