MIBs Provided with TCP/IP Services
2.2 Overview of MIB II
2.2.1 MIB II Implemented Groups
A group is a subdivision of a MIB that defines a subtree. SNMP as implemented
by TCP/IP Services supports the following groups:
•
system (1)
•
interfaces (2)
•
Internet Protocol (4)
•
ICMP (5)
•
TCP (6)
•
UDP (7)
•
SNMP (11)
In the SNMP group (1.3.6.1.2.1.11), data elements with the status noted as
obsolete in RFC 1907 are not implemented.
Note
The TCP/IP Services implementation of SNMP does not support the
following defined MIB II groups:
•
at
(address translation) group
•
EGP
(External Gateway Protocol) group
•
transmission
group
2.2.2 Restrictions to MIB II Implementation
SNMP requests are not implemented for the following MIB II objects:
ipRouteMetric1 - ipRouteMetric5
tcpMaxConn
SNMP
set
requests are not implemented for the following MIB II group objects:
ipDefaultTTL
ipRouteAge
ipRouteDest
ipRouteIfIndex
ipRouteMask
ipRouteNextHop
ipRouteType
The TCP/IP Services implementation of SNMP includes the following MIB II
objects:
•
sysObjectID
is returned in the following format:
1.3.6.1.2.1.1.2.0 = 1.3.6.1.4.1.36.2.15.13.22.1
where 1.3.6.1.4.1.36.2.15.13.22.1 corresponds to:
iso.org.dod.internet.private.enterprises.dec.ema.SysObjectIds.DEC-OpenVMS.eSNMP
• The
sysORTable
elements are under OID prefix 1.3.6.1.2.1.1.9.1. See RFC
1907 for details.
