Using Device Manager or the CLI, you can enable RMON globally or on a port-by-port basis. Implementing RMON lets you set alarms relating to specific events or variables.

Refer to Reference for the Passport 8000 Series Management Software Switching Operations for more information on alarms.

Table 203 lists the alarms that are specific to the Passport 8683POS Module. The alarms are listed in order of priority.


Name	Description
Section alarms
LOS	Loss of signal - not enough Rx power or fiber disconnected.
LOF	Loss of frame - unable to frame the signal correctly, possibly due to improper timing setup.
Line Alarms
L-AIS	Alarm Indication Signal - sent out when a port is disabled or indicates another line failure.
L-RDI	Remote Defect Indication - the result of a L-AIS or LOS/LOF at the remote end.
Path Alarms
P-AIS	Path Alarm Indication Signal - indicates a propagation upstream of a downstream L-AIS alarm or another path failure.
P-LOP	Path Loss of Pointer - the pointer to the Sonet SPE is not correct; sometimes due to dirty fiber, or timing slips.
P-RDI	Path Remote Indicator - the result of a P-AIS alarm at the remote end.
P-SLM	Path Signal Label Mismatch - path labels do not match, in particular the C2 label is mismatched. (The C2 label is used to indicate scrambling according to RFC 2615.)
P-UNEQ	Path is unequipped - the path is may not be provisioned to handle traffic cross-connects.
