Hi,
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
