BydefaultanSNMPagentonlylistenstorequestsfromport161.However,youcan
configurethissotheagentlistenstorequestsonanotherport.
EntertheportnumberonwhichyouwanttheSNMPagentstolistentorequests.
Thevalid
rangeis1‐65535.
Note:ThisisaglobalSNMPparameterthatappliestoSNMPv1,SNMPv2c,and
SNMPv3.
AllowSNMPsetrequests YoucanchoosewhetherornottoallowSNMPsetrequestsontheAP.Enabling
SNMPsetrequestsmeansthatmachinesonthenetworkcanexecuteconfiguration
changesviathe
SNMPagentontheAPtotheD‐LinkSystemMIB.ToenableSNMP
setrequests,clickEnabled.TodisableSNMPsetrequests,clickDisabled.
Read‐writecommunity
name(forpermitted
SNMPsetoperations)
IfyouhaveenabledSNMPsetrequestsyoucansetaread‐writecommunityname.
Thevalid
rangeis1‐256characters.
Settingacommunitynameissimilartosettingapassword.Onlyrequestsfromthe
machinesthatidentifythemselveswiththiscommunitynamewillbeaccepted.
Thecommunitynamecanbeinanyalphanumericformat.
Restrictthesourceof
SNMPrequeststoonly
thedesignatedhostsor
subnets
YoucanrestrictthesourceofpermittedSNMPrequests.
TorestrictthesourceofpermittedSNMPrequests,clickEnabled.
Topermit anysourcesubmittinganSNMPrequest,clickDisabled.
Hostname,addressor
subnetofNetwork

SpecifytheIPv4DNShostnameorsubnetofthemachinesthatcanexecutegetand

setrequeststothemanageddevices.Thevalidrangeis1‐256characters.
Aswithcommunitynames,thisprovidesalevelofsecurityonSNMPsettings.The
SNMPagentwillonlyacceptrequestsfromthehostnameorsubnetspecifiedhere.
Tospecifyasubnet,enteroneormoresubnetworkaddressranges
intheform
address/mask_lengthwhereaddressisanIPaddressandmask_lengthisthe
numberofmaskbits.Bothformatsaddress/maskandaddress/
mask_lengtharesupported.Individualhostscanbeprovide dforthis,i.e.I.P
AddressorHostname.Forexample,ifyouenterarangeof
192.168.1.0/24 this
specifiesasubnetworkwithaddress
192.168.1.0 andasubnetmaskof
255.255.255.0 .
TheaddressrangeisusedtospecifythesubnetofthedesignatedNMS.Only
machineswithIPaddressesinthisrangearepermittedtoexecutegetandset
requestsonthemanageddevice.Giventheexampleabove,themachineswith
addressesfrom
192.168.1.1 through 192.168.1.254 canexecuteSNMP
commandsonthedevice.(Theaddressidentifiedbysuffix.0inasubnetworkrange
isalwaysreservedforthesubnetaddress,andtheaddressidentifiedby.255inthe
rangeisalwaysreservedforthebroadcastaddress).
Asanotherexample,ifyouenterarangeof
10.10.1.128/25 machineswithIP
addressesfrom
10.10.1.129 through 10.10.1.254 canexecuteSNMP
requestsonmanageddevices.Inthisexample,
10.10.1.128 isthenetwork
addressand
10.10.1.255 isthebroadcastaddress.126addresseswouldbe
