I tried my best to figure out your topology, I hope I have got you right. You connect the 108E to the front switch via port 8 and you set 2 VLAN (VLAN 2 and VLAN 3) in the 108E. Port 1-2 is for VLAN...

For easy smart switch, there is no management VLAN which means you can access the switch via any VLAN; if you enable DHCP, the switch can get the management IP address automatically from the front...

The TL-SG2210P supports SSL and SSH which means you can use htps and SSH to access; if you want to block telnet and telnet, you can try to set ACL to block these connections.

So, have your problem solved now?
