Hello, I have what I hope is a simple issue to resolve.
I have a MS350 switch that I want to setup with a static IP address. My problem however is that it keeps setting itself back to DHCP no matter what I do/try.
My management VLAN is 1 but the IP I want to use is on VLAN 2. From my point of view it looks no different than all my other switches configured with the same VLANs, but I cannot figure out why this one has an issue.
Yeh... This has been a real pain in my butt as well.
Call into support. They have some settings they can apply to help convince the MX to stick to its static and not fall back to DHCP so easily.
gateway of your ip adres in vlan 2 is also at the upstream / internet device?
Yes.
Have you tried keeping it at DHCP and then giving it a fixed IP assignment from the DHCP page? Since doing that, we've had zero issues getting our devices to the IPs we want.
Also, are you trying to set the static IP from the local admin page of the device or from the dashboard?
I also dealt with this once. Two pieces of advice worth checking:
1. Double check you didn't mix up the gateway and subnet mask in the wrong boxes. I've done it.
2. Sometimes it takes a bit for the static IP to stick. Especially if the devices has been rebooted a lot. I had one that didn't take it until overnight.
Lastly as said by some of the other guys here. Double check the port has the right vlan and the upstream configuration is the same.
