Purpose
Provides the
boot and engine ID information for the snmpdv3 agent.
Description
The snmpt.boots file provides the boot and engine ID information
for the snmpdv3 agent. The file contains two elements: an engineID, and, engineBoots, the number of times that the snmpv3 daemon has been started.
Syntax
engineID engineBoots
The following list explains the variables in the syntax:
- engineID
- A string of 2 to 64 (must be an even number) hexadecimal digits.
The engine identifier uniquely identifies the agent within an administrative
domain. By default, the engine identifier is created using a vendor-specific
formula and incorporates the IP address of the agent. However, users
can choose to use any engine identifer that is consistent with the snmpEngineID definition in RFC 2271, and that is also unique
within the administrative domain.
For the engineID that is associated
with an IPv4 address, the first 8 hexadecimal digits represent a vendor
enterprise ID obtained from the Internet Assigned Numbers Authority
(IANA). For
IBM®, this
ID is 00000002. The last 16 hexadecimal digits are determined by vendor-formula.
For
IBM, the formula
follows these rules:
- The first two hexadecimal digits indicate the content of the next
14 hexadecimal digits.
- The string 00 indicates that the next 6 hexadecimal
digits are zeros, followed by the IP address of the agent in the last
8 hexadecimal digits.
- The string 01 indicates that the next 6 hexadecimal
digits contain a time stamp, followed by the IP address of the agent
in the last 8 hexadecimal digits.
The agent is always used without a time stamp, so the engineID
for an SNMP agent at IPv4 address
9.67.113.10 is
00000002 00000000 09 43 71 0A (spaces are added for clarity).
An engineID associated with an IPv6 address follows these rules:
- The first 4 octets 80000002, which are a hexadecimal
value, is an IANA assigned enterprise number.
- The 5th octect 02, which is a hexadecimal value,
indicates that it is an IP address.
- The 6th octet to the 31st octet are hexadecimal values of the
16 bytes IPv6 address.
For example, the engineID for an SNMP agent running on IPv6 address
2000:1:1:1:209:6bff:feae:6d67 is
80000002 02 200000010001000202096BFFFEAE6D67 (spaces are added for clarity).
- engineBoots
- The number of times (in decimal) the agent has been restarted
since the engineID was last changed.
Note: - engineID and engineBoots must be specified in order and on the
same line.
- Comments are specified in the file by starting the line with either
an asterisk (*) or a pound sign (#).
- No comments are allowed between engineID and engineBoots values.
- Only the first non-comment line is read. Subsequent lines are
ignored.
Example
The first
string of numbers is the
engineID, the second string is the
number of times the
snmpv3 daemon has been started.
