This ruleset is designed to detect which of a set of Cisco ASAs are active and which is on standby. In addition, when either changes from primary to secondary or vice versa an email alarm will be sent indicating such.
To load these rules on your Lantronix LM, copy and paste the below rules and rulesets into the CLI on the system resource.
To schedule the monitors, on the primary ASA's port run the command config monitor chassis fsd1, and on the secondary ASA's port run the command config monitor chassis fsd2.
