CSS326-24G-2S+ does not accept dhcp-provided IP!?

Sat Dec 22, 2018 3:08 pm

Hello,

I'm trying to integrate my shiny new CSS326-24G-2S+ into my network. And am pluggin it into my dhcp-serving firewall. dansmasq recognizes the switch and offers it my custom IP, but it appears to not accept it and falls back to it's default (see below journalctl -f log).

What may I be missing?

Sincerely, Joh

Does the CRS326 have a ip > DHCP Client entry setup? Looks like it's running a DHCP Server (not client)...

If so, disable DHCP Server, and set a DCHP Client on top of the bridge interface where all ports are.

The CSS326 runs SwitchOS and does not have a DHCP server. Although I normally run all of my switches with static IPs, I remember when I first got them and they factory defaulted to DHCP with fallback, the DHCP client worked.
What is the setting of the Address Acquisition on the System tab?
Also, what SwitchOS version (from the Upgrade tab)?
RB750Gr3, RB750r2, CRS326-24G-2S (in SwitchOS), CSS326-24G-2S, CSS106-5G-1S, RB260GS
Not sure if I beat them in submission, or they beat me into submission
