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?

What brand of switches are you using?2.
When you say you're unable to reach the 2nd switch, what do you mean? Do you mean a host connected to the 1st switch can't communicate with a host connected to the second switch?3.
Regardless of switch brand, frames transiting the trunk link need to be tagged with the VLAN ID of the VLAN they came from in order to reach a port in the same VLAN on the other switch. In a Cisco switch this is calledtrunking
. In an HP switch this is calledtagging
.1.
I cannot ping the management ip of the 2nd switch which is linked.2.
If I plug in a regular ethernet cable between switch 1 and 2 then I'm able to reach the 2nd switches management interface.
