My network is running fine. However I have a question on the different treatment of default vlan id (0 or 1) across different products for switch chip VLAN implementation.
On the HAPAC2, this is the setting: (I assume with the port default vlan empty, it defaults to 1)
On the Powerbox, the default port vlan is 0 (which I assumed to be treated the same as 1). However, if I don't add "vlan=0" in the switch vlan table, when I enable "VLAN Mode = Secure" for the uplink port, the winbox connection to the switch cuts. Now I am thinking MT treats vl 0 and 1 differently (whereas I previously assumed they are treated the same way).
For trunk ports, should I:
1. Set the default vlan id on the HAPAC2's ports to 0 and add VL=0 to the vlan table? or instead
2. Set the default vlan id on the Powerbox's ports to 1?
More info:
On the main MT router, trunk ports on the bridge come with default port vl-id=1 (thus I assumed MT's native vlan-id is 1 for trunk port default untagged traffic). Now after introducing the powerbox to the network, I am not so sure.
