i have 3 c3750e-pd-sf switches. they talk very well to each other, and to printers, or desktops, ... but they refuse to talk to any unmanaged, or non cisco switches (trendnet tegs24tg, netgear fs726tp, trendnet green gb8pt), or my routers (tp-link ac1900, netgear nighthawk). if the ports are not in trunking mode they amber light down the port, if in trunking, even with only vlan1 on the switch, they will not pass data.
i do not care about the old switches as they are going away with this upgrade (but might need a local in a spot or two due to limited connections), but they are acting the same way as for my routers.
these switches are to be in two locations with a hot spare. one in the basement and one in the garage, connected via two 10g mm fiber (vlan 1,102 and vlan 103,1000).
vlan1 is LAN general traffic
vlan102 is servers backbone
vlan103 is cameras
vlan1000 is WAN
my cisco certs are.... well 25yrs ago, and my old hardware... (2501, c2900, ect) long scrapped.
thanks
