Help on vlans config

RouterOS Beginner Basics
1

Hello,
First sorry my english. I am a new user of mikrotik (RB-1100AHx4 with switch build in and ROS v4.46). I have somes questions for help and understanding :

  1. Why the build in swich is separted in 3 groups : switch1 (port 1-5) switch2 (6-10) switch3(port 11-13) ? Does it mean that those port are different and cant used in the same way of standard switch like tplink’ dlink, … ?
  2. On my ROS, i want to create many vlans (7) one for each subnet (isolated and IP 10.1.10.0/24, 10.2.10.0/24, …, 10.7.10.0/24) but share one WAN connection (IP 172.16.1.1/24). The ROS is connected to a tplink swich with same vlans (L2t. How i do that (with optimization on CPU) ? Wat is the best solution : conectiong ROS-TPLINK : using 7 cable (portvaln ROS to port vlan TPLINK) or using 1 cable on a trunk port in TPLINK ?
    Please help me ( command ode ROS are welcome).
    Thanks.

Upgrade your Software version to at least 6.48.6 long terms.
Do a search on the forum and figure out if people are using Chip based vlan switching or bridge vlan filtering for your particular device.
