SNMP Private Enterprise MIB Structure
The XL-GPS SNMP agent will send SNMP version 1 traps. This is done to maintain
compatibility with SNMPv1 managers.
The trap presently defined is: alarmSystemNotification
The alarmSystemNotification trap is sent when the state of an object in the
systemStatusDetail group changes and the corresponding mask object in the
configDataMasks group is enabled.
Future Expansion
This section outlines the possibilities for future expansion of the Symmetricom Enterprise
MIB. The general overview is that new objects may be added to any location. Existing
objects may not be altered in order to maintain backward compatibility. There are two
varieties of expansions to consider: additional products and additional features within an
existing product.
This model makes adding additional products and maintaining compatibility a straightforward
process. Each additional product will be given a branch in the tree under
enterprises.SymmetricomTtm.products. For now, we have only
enterprises.SymmetricomTtm.products.xlGps and
enterprises.SymmetricomTtm.products.nic56k.
Future products will take the form enterprises.SymmetricomTtm.products.product.XXX.
Each product will use enterprises.SymmetricomTtm.products.product.XXX as its system
object identifier. Each product will also define an
enterprises.SymmetricomTtm.products.product.XXX.xxxTrap subgroup for the definition of
all enterprise specific traps that can be generated by that product.
Making additions to the XL-GPS product MIB is also a straightforward task with several
caveats. The first is that additions may be made but the object identifier and the semantics of
existing objects may not be altered. A likely place for additions is under the
systemStatusDetail group as addition system objects are defined.
Glossary of SNMP-Related Terms
Depreciation: In SNMP when an SNMP variable or group of variables is no longer
recommended for use, they are listed as deprecated in the formal definition of the MIB.
Users are often times still allowed to use this data, but the MIB’s authors for one reason or
another no longer recommend it.
Enterprise MIB: See Private Enterprise MIB.
IANA - Internet Assigned Number Authority: This is the group at IETF that is in charge
of assigning Internet related numbers like Ethernet addresses, TCP/UDP port numbers and
SNMP Private Enterprise MIB numbers.
