Key:

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.

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	ntsControl = 3	gps = 4	acts = 5
TrapMsg = 1	ntp = 2
