SIGLOSS
Default Severity: Major (MJ), Service-Affecting (SA)
Logical Objects: FC, GE, ISC, TRUNK

there is a loss of signal. (Loss of Gigabit Ethernet client signal results in a CARLOSS [GE], not SIGLOSS.)
SIGLOSS can also be raised on the XP and MXP trunk port.

If the SYNCLOSS alarm was previously raised on the port, the SIGLOSS alarm will demote it.
