I’m struggling with getting a VLAN setup to work between my Peplink Balance 20 router and my VLAN-aware switch and VLAN-aware WiFi access points. To help me understand what expectations I should have, and hence guide me towards correct settings on the switch and WAPs, I think I need answers to some basic questions. I’m hoping folks here can give me some definitive and reliable answers.
In the Balance 20 Web Admin portal, if I go to Network > LAN > Network Settings, there is a list of defined LANs in a table which shows the VLAN and Network (IP address & mask). Say I have defined a LAN called “ExtNet44” with VLAN=44. Then, in Network > LAN > Port Settings, for LAN Port 4, I set port type to “Access” and VLAN to “ExtNet44”. With this configuration, what is the router behavior for each of the following scenarios:
- Outbound Frame (leaving the router on Port 4) – is it TAGGED with VLAN=44, or is it untagged?
- Inbound Frame (coming into router at Port 4), when frame is tagged with VLAN=44
- Inbound Frame, when frame is tagged with VLAN != 44
- Inbound Frame, when frame is untagged
Next, if I set Port Type to “Trunk” for Port 4 instead of “Access”, do any of the answers to these questions change? If so, what is different?
