alarm on page
common causes of the CARLOSS alarm are a disconnected cable, an Ethernet Gigabit Interface
Converter (GBIC) fiber connected to an optical card rather than an Ethernet device, or an improperly
installed Ethernet card. Ethernet card ports must be enabled for CARLOSS to occur. CARLOSS is
declared after no signal is received for approximately 2.5 seconds.
The CARLOSS alarm also occurs after a node database is restored. After restoration, the alarm clears in
approximately 30 seconds after the node reestablishes Spanning Tree Protocol (STP).
