Question

我正在尝试通过SNMP从服务器收集数据。 snmpwalk不会像Web界面那样返回任何基本数据，但我需要通过SNMP获取这种数据。

snmpwalk -c public -v 1 <ip> .

iso.3.6.1.2.1.1.1.0 = STRING: "OCMF agent SNMP"
iso.3.6.1.2.1.1.2.0 = OID: iso.3.6.1.4.1.11606.0
iso.3.6.1.2.1.1.3.0 = Timeticks: (95236803) 11 days, 0:32:48.03
iso.3.6.1.2.1.1.4.0 = STRING: "helpdesk@pbn.com.au"
iso.3.6.1.2.1.1.5.0 = STRING: "Copyright(c)2004 Pacific Broadband Networks"
iso.3.6.1.2.1.1.6.0 = STRING: "8 Keith Campbell Court"
iso.3.6.1.2.1.1.7.0 = INTEGER: 0
iso.3.6.1.2.1.11.1.0 = Counter32: 6505
iso.3.6.1.2.1.11.2.0 = Counter32: 6580
iso.3.6.1.2.1.11.3.0 = Counter32: 127
iso.3.6.1.2.1.11.6.0 = Counter32: 41
iso.3.6.1.2.1.11.15.0 = Counter32: 225
iso.3.6.1.2.1.11.16.0 = Counter32: 6285
iso.3.6.1.2.1.11.17.0 = Counter32: 0
iso.3.6.1.2.1.11.18.0 = Counter32: 0
iso.3.6.1.2.1.11.19.0 = Counter32: 0
iso.3.6.1.2.1.11.25.0 = Counter32: 0

iso.3.6.1.2.1.11.27.0 = Counter32: 0
iso.3.6.1.2.1.11.28.0 = Counter32: 6516
iso.3.6.1.2.1.11.29.0 = Counter32: 75
iso.3.6.1.4.1.11606.1.1 = INTEGER: 1
iso.3.6.1.4.1.11606.1.2 = INTEGER: 255
iso.3.6.1.4.1.11606.1.3 = INTEGER: 0
iso.3.6.1.4.1.11606.1.4 = INTEGER: 0
iso.3.6.1.4.1.11606.1.5 = INTEGER: 0
iso.3.6.1.4.1.11606.1.6 = INTEGER: 1357399287
iso.3.6.1.4.1.11606.1.15 = INTEGER: 1357399287
End of MIB

如果我在/etc/snmp/snmp.conf中启用OID解析，我得到：

SNMPv2-MIB::sysDescr.0 = STRING: OCMF agent SNMP
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.11606.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (95258487) 11 days, 0:36:24.87
SNMPv2-MIB::sysContact.0 = STRING: helpdesk@pbn.com.au
SNMPv2-MIB::sysName.0 = STRING: Copyright(c)2004 Pacific Broadband Networks
SNMPv2-MIB::sysLocation.0 = STRING: 8 Keith Campbell Court
SNMPv2-MIB::sysServices.0 = INTEGER: 0
SNMPv2-MIB::snmpInPkts.0 = Counter32: 6534
SNMPv2-MIB::snmpOutPkts.0 = Counter32: 6609
SNMPv2-MIB::snmpInBadVersions.0 = Counter32: 127
SNMPv2-MIB::snmpInASNParseErrs.0 = Counter32: 41
SNMPv2-MIB::snmpInGetRequests.0 = Counter32: 225
SNMPv2-MIB::snmpInGetNexts.0 = Counter32: 6314
SNMPv2-MIB::snmpInSetRequests.0 = Counter32: 0
SNMPv2-MIB::snmpInGetResponses.0 = Counter32: 0
SNMPv2-MIB::snmpInTraps.0 = Counter32: 0
SNMPv2-MIB::snmpOutGetRequests.0 = Counter32: 0
SNMPv2-MIB::snmpOutGetNexts.0 = Counter32: 0
SNMPv2-MIB::snmpOutSetRequests.0 = Counter32: 0
SNMPv2-MIB::snmpOutGetResponses.0 = Counter32: 6545
SNMPv2-MIB::snmpOutTraps.0 = Counter32: 75
SNMPv2-SMI::enterprises.11606.1.1 = INTEGER: 1
SNMPv2-SMI::enterprises.11606.1.2 = INTEGER: 255
SNMPv2-SMI::enterprises.11606.1.3 = INTEGER: 0
SNMPv2-SMI::enterprises.11606.1.4 = INTEGER: 0
SNMPv2-SMI::enterprises.11606.1.5 = INTEGER: 0
SNMPv2-SMI::enterprises.11606.1.6 = INTEGER: 1357399287
SNMPv2-SMI::enterprises.11606.1.15 = INTEGER: 1357399287
End of MIB

我想获取Web界面中可用的同一组参数

1.MTEMP 30C O
1.LCUR 61mA O
1.LPWR 09.9mW Z
1.OMI 04.2％Z
1.ERF 20.5dBmV O
1.RFI 41.9dBmV O
1.RFO 36.6dBmV Z
1.LTEMP 31C O

这可能吗？

The dump you've provided as a result of snmpwalk command is just a snapshot of RFC1213 (mib-2) data. And yes your assumptions are correct: It is not the information you're interested in as it only contains the set of data about network interfaces and common system information (system group of MIB-II). You'll need to contact your vendor to get specific set of MIB files for this particular device. Usually the target MIB files are available on vendor's web site in Download area. The data you'd like to retrieve is usually located in private enterprise specific branch of MIB tree.

From what I see the Enterprise OID 1.3.6.1.4.1.11606 belongs to Pacific Broadband Networks (PBN).

Also I've found the definition for the root element of this MIB module:

PBN-ROOT DEFINITIONS ::= BEGIN

IMPORTS
     enterprises
          FROM RFC1155-SMI;

pbn  OBJECT IDENTIFIER ::= { enterprises 11606 }

END

snmpwalk没有显示所需的所有信息
