Configuring Junos OS to Enable the TX Matrix Plus Router to Generate an Alarm If a T1600 or T4000 Router Stays Offline
By default, the Junos OS enables all the T1600 or T4000 routers in the routing matrix to come online. The Junos OS also enables you to configure all the T1600 or T4000 routers so that if they do not come online, an alarm is sent by the TX Matrix Plus router.
To configure this alarm, include the online-expected statement at the [edit chassis lcc number] hierarchy level:
If you do not want a T1600 or T4000 router to be part of the routing matrix, you can configure it to be offline. This is useful when you are performing maintenance on a T1600 or T4000 router. When the T1600 or T4000 router is ready to come back online, delete the offline configuration statement.
To configure a T1600 or T4000 router so that it is offline, include the offline statement at the [edit chassis lcc number] hierarchy level:
If you do not configure the online-expected or offline statement, any T1600 or T4000 router that is part of the routing matrix is allowed to come online. However, if a T1600 or T4000 router does not come online, the TX Matrix Plus router does not generate an alarm.
