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 wsitches. 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.
