SNMP Private Enterprise MIB Structure
This section describes the top level structure & design of the XLi SNMP Private Enterprise MIB.
SNMP Addressing
SNMP addressing is structured as a very large tree database. A root node address is an integer value
that ranges from 0 to some very large number. Conceptually, there are no limits to the numbers of sub
nodes either. SNMP addressing is written in “doted decimal” notation. For example the address of
Symmetricom’s ntpInPkts Enterprise MIB variable is “1.3.6.1.4.1..1896.6.1.2.1.1.0”. The address
fragment 1.3.6.1.4.1 is fixed by the IANA (Internet Assigned Number Authority) and is the address of the
SNMP Private Enterprise MIB’s. The 1896 is the address assigned by IANA to Symmetricom for our
Enterprise MIB’s. Symmetricom assigns the addresses after that at our discretion and design.
New Top Level Structure of Enterprise MIB for XLi
The former address structure of Symmetricom’s Enterprise MIB is as follows:
TrueTimeEnt = 1896
TrapMsg = 1 ntp = 2 ntsControl = 3 gps = 4 acts = 5
MIB=/config/ttmib.o,
Don’t touch. This is a factory setting.
GenTraps=YES, Global enable/disable setting for all SNMP traps. YES, the default setting,
enables all traps. NO disables all traps. This setting overrides all the other TRAP
parameter settings.
NAME = the community name password. This should be the same as the community
name being used by the administrator's
VIND = View Index. This is a reserved term that has no effect and is currently unused in
SNMP. This parameter should be set to “1”.
TRAP = YES enables/NO disables SNMP traps for a particular community.
ACCESS = Read and write privileges to members of a community. R sets read only
privileges, and W sets read and write privileges.
IP = Provide the IP address of the SNMP management stations within that
community. These addresses are required in order for the management station
to receive SNMP traps and to communicate with the XLi system using SNMP.
Note: A special address of 255.255.255.255 grants any IP addressed unit
access to the Enterprise MIB variables.
