Backup Routing Engine Alarms
For routers with master and backup Routing Engines, a master Routing Engine can
generate alarms for events that occur on a backup Routing Engine. Table 70 on page 309
lists chassis alarms generated for events that occur on a backup Routing Engine.
NOTE: Because the failure occurs on the backup Routing Engine, alarm
severity for some events(such asEthernet interface failures) is yellow instead
of red.
