+"""
+This plugin can check the status of one or more IP SLA entries on a Cisco IOS device.
+IP SLAs can be used to monitor IP service levels for various IP applications and services. See the Cisco website
+for more details on SLA entries and their use. One simple usage example is to monitor a multi-connection
+failover routing setup to monitor SLAs which ping the other end of each line. SLA's can be set up to monitor
+a line/route and when this line goes down, the corresponding SLA will go down which this plugin can monitor.
+This is just one example, however SLAs can be configured for various other tasks.
+For more info on IP SLA's, see the manual for your Cisco device on IP SLA's.
