Summary
Detect Internet is a tool that categorizes monitored interfaces into following states - Internet, WAN, LAN, unknown and no-link.
LAN
All layer 2 interfaces initially have this state.
WAN
Any L3 tunnel and LTE interfaces will initially have this state. Layer 2 interfaces can obtain this state if:
- interface has an active route to 8.8.8.8 in main routing table.
- interface can obtain (or has obtained) an address from DHCP (does not apply if DHCP server is also running Detect Internet on the DHCP server interface).
Note: WAN interface can fall back to LAN state only when link status changes.
Note: LAN interfaces get locked to LAN after 1h and then change only when link status changes.
Internet
WAN interfaces that can reach cloud.mikrotik.com using UDP protocol port 30000 can obtain this state. Reachability is checked every minute. If cloud is not reached for 3 minutes, state falls back to WAN.
Configuration
Sub-menu: /interface detect-internet
| Property | Description |
|---|---|
| detect-interface-list (interface list; Default: none) | All interfaces in the list will be monitored by Detect Internet |
| internet-interface-list (interface list; Default: none) | Interfaces with state Internet will be dynamically added to this list |
| lan-interface-list (interface list; Default: none) | Interfaces with state Lan will be dynamically added to this list |
| wan-interface-list (interface list; Default: none) | Interfaces with state Wan will be dynamically added to this list |
State
Sub-menu: /interface detect-internet state
This submenu displays status of all monitored interfaces defined by detect-interface-list parameter.
