all of my switches use 169.254.0.239
I have several GC728X switches, most 28 port, a few 52, firmware v1.0.5.32. All list their connected neighbor switch as the same IP that appears in the Mangment IP for all devices. Except 2 GC108P 8port switches which show the static IP assigned to them which also appears as the MNGT IP .
I have been having random service drops and while some believe it is solely an issue on the ISP side of the modem, I can't see how 6 switches all using the same IP, mngt or not, could be good. I did some packet sniffing and there's a lot of broadcast for who has 169.254.0.239 ... why are these switches using a default IP instead of the static IP assigned to them? I've seen slightly similar issues mentioned but would like some insight before having to reset and reconfigure the whole network.

Static IP == DHCP reservation, or a static IP config on the switch?
With DHCP, what can happen is that if the switch does not get an IP config by DHCP within a relatively short time, the switch will fall-back to the default IP address.
the Static IP cinfigured on the switch. Apparently since all the IP on this network are assigned there is no DHCP running

yay for inheriting a buggers network
This befuddles me why every connecting port says the same IP for every device AND the Topology view doesn't coincide with the Connected Neighbor pages.
Can anyone tell me why, if there is no DHCP on my network and the switches are configured with static IP, does the port connecting the backbone devices default?
Probably not. Wild guess something like a random config reload, which does fail at some point - before the management IPs are set again. Or some part of the config are skipped or error-out...
