I linking 2 different brand of switches (Linksys & Zyxel) through SPF gigabit connector.
g4 1G-Combo-F Full 1000 Enabled Off Up Disabled Off
It says the link is up but I still unable to reach the 2nd switch through the uplink (no other cable plugged into it yet, if I just link it with an ethernet cable on any other port it works). I know a lot of things can go wrong here so I would like to start with the beginning.
Both switches have 7 different vlans defined manually with the exact same vlan IDs.
Do the Trunk ports needs to be tagged or untagged on both switches?
