SNMP Private Enterprise MIB Structure
Note: For the figures in this chapter, substitute “xlgps” for “xli”.
The level under the XL-GPS group is divided into three groups; the first two of which will be
explained later. The optionCardGroup has all the available option cards under it.
The current traps message group is located under the fault. The ntp group is under the
xlGpsMainCard group as an option, and is related only to NTP on the standard network port
on the XL-GPS’s Main CPU card.
This MIB structure also provides a useful definition for the system object ID. SNMP
managers may use the system object ID to identify the class of object being accessed. With
this structure, the system object ID is defined as Symmetricom.products.xlGps for the XL-
GPS product and Symmetricom.products.xxx for all subsequent products.
XL-GPS System Group
The xlGpsSystem system group contains the systemFault and the systemStatus groups.
These groups contain information describing the operation of the XL-GPS system as a
whole. The systemFault group contains information concerning system faults that have
occurred, as well as configuration parameters for the generation of system alarms, called
traps in SNMP, resulting from those faults. The systemStatus provides two different views of
the operational system. The first is a general view specifying if the clock is operational. The
second is a detailed view containing the current status of each system component. The
systemFault and systemStatus groups are described below.
