Today I noticed an oddity that I can’t figure out for some reason.
Have a balance 210 running speedfusion; on the LAN side it has 2 LAN ports assigned to individual separate vlans, and then the rest of the LAN ports are untagged vlan. So far I’ve only had one computer hooked to an untagged vlan port and the rest of the untagged lan ports empty.
Balance has IP 192.168.1.1.
Untagged vlan is 192.168.1/24
Today when connecting a second computer to a second untagged vlan port, I noticed the orange traffic lights of LAN1 and LAN2 are blinking in unison when there is traffic to either computer such as doing a speedtest. With the computers idle, if I simply do a ping from one of the computers, I notice the other computer’s lan port on the balance also blinks to the rhythm of the ping.
Computer 1 is set with static IPv4
192.168.1.20
subnet mask 255.255.255.0
gateway 192.168.1.1
Computer2 is set with static IPv4
192.168.1.22
subnet mask 255.255.255.0
gateway 192.168.1.1
ipV6 is off on both computer1 and computer2
What would cause this or what should I look at?
Those lights just mean there is activity on that interface. They will blink in unison some times (often) due to broadcast traffic. Things like ARP, DHCP, SSDP, etc will be broadcast to all interfaces in the Lan segment.

Did it look like this because I don’t know what that means either…

Fwiw - that is not what I was talking about. That is weird. What is on the other end of that cable? Is that router functional?
Thanks!
No, in my quandary, it’s just the traffic lights for the two untagged vlan LAN ports seem oddly syncronized.
On both LAN1 and LAN2 the green light is steady on and the orange light is steady on when both computers are idle (both normal.)
But if I initiate a ping on one computer to the gateway IP 192.168.1.1 or to 8.8.8.8 the orange traffic light on LAN1 and the orange traffic light on LAN2 seem to blink exactly in unison with the ping response. If I stop, both stop. If I start, both show traffic together.
I thought about broadcast traffic, but it seems odd to me; maybe I just haven’t been observant up to this point but I don’t remember seeing switch lights this synchronized before…
