just got a GL-AR750S and am trying to understand what I’m seeing with
ifconfig and how it relates to how the device physically looks like.
Physically the device has:
- wifi 2.4G
- wifi 5G
- WAN ethernet port (1st in direction left->right)
- LAN ethernet port (2nd in direction left->right)
- LAN ethernet port (3rd in direction left->right)
A compressed view of
ifconfig -a and
brctl show (some interfaces were skipped) :
br-lan * bringing eth0.1, wlan0 and wlan1. Conceptually that is a switch with 3 ports. * the bridge itself [has an IP address](https://unix.stackexchange.com/questions/319979/why-assign-mac-and-ip-addresses-on-bridge-interface) (192.168.8.1) serving as the web UI eth0 * A normal Ethernet interface * Not clear how does it relate to the two physical Ethernet ports and what can one do with it? eth0.1 * A VLAN interface * Not clear how does it relate to the two physical Ethernet ports? eth0.2 * Another VLAN interface * This seems to be tied physically to the WAN port. It has an external IP when it's connected to a gateway * Due to being in a separated VLAN this is only accessible via routing wlan0, wlan1 * guessing these represent access points for the 2.4G and 5G wifi's teql0 * don't know what this is
This is as far as I got.
If someone can fill up the unknowns or correct what’s wrong, please feel free to
