Ubiquiti Service Switching

This ruleset monitors the signal level of the Ubiquiti and triggers the shutdown of an interface on a router when the level goes below -75 for three consecutive checks. When the signal level is above -75 db for three consecutive checks the router's interface is turned on again.

Usage

First, replace INTERFACE-NAME-GOES-HERE in the ubiquitiRouterInterfaceOff and ubiquitiRouterInterfaceOn rules below with the name of the router interface to be controlled.

To load the rules, copy and paste the rules and rulesets into the system level of the Lantronix Local Manager's CLI.

To schedule the rules on the Ubiquiti, switch to the Ubiquiti's port with the port 4/1 command and issue the command config monitor chassis ubiquitiCheck. Validate the monitor by pressing "y".

Finally, to schedule the rules on the router, switch to the Router's port and run the command config monitor chassis ubiquitiRouterInterface.
