QoSMapTable
Eachrowofthetablecorrespondstoonematchfilterallowingupto8
distinctfilterstoidentifyandassignapriorityvaluetoreceivedEthernet
packets.Eachfilterhasseveralparametersthatcanbeenabledbyclickingon
itscheckbox.Whenmultipleparametersareenabled,allmustmatchbefore
thePrior
ityvalueisassignedtoapacket.

Thefollowingprioritymapfilterfieldsaresupported:

 Priority–ThepriorityvaluetoassigntothereceivedEthernet
frameifitwasnotalreadymarkedwithapriorityvalueandifall
enabledfilterfieldsmatch.
 SourceIPAddress–Afieldmatc
hoccursforallpacketsreceived
fromthedevicewiththeenteredIPaddress.
 DestinationIPAddress–Afieldmatchoccursforallpackets
receivedaddressedtothedevicewiththeenteredIPaddress.
 SourcePortNo.–AfieldmatchoccursforallIPpacketsreceived
withthissourc

 DestinationPortNo.–AfieldmatchoccursforallIPpackets
receivedwiththisdestinationportvalue.
 ProtocolNo.–AfieldmatchoccursforallIPpacketsreceivedwith
thisprotocolnumber.
 PacketLength–Thisfieldcontains2sub‐fields.Aneditboxto
enterapacketlengththreshold,andcheckboxestoselectwhether
afieldmatchoccursifthelengthofthereceivedpacketislessthan
thethresholdorifitisgreaterthanorequaltothethreshold.

RapidSpanningTreeFunctionality
TheRapidSpanningTree(RSTP)optionisanadvancednetworkingfunctionthatshuts
offportsasnecessarytopreventdatapacketloopswhenmorethanonenetworkpath
isavailable.IfloopsarecreatedinanEthernetnetwork,packetscanbecirculate d
endlessly,consumingallthebandwidthandmakingthene tworkunusable.
RSTPallowsuserstocreat
etrulyredundantconnectionsbetweenanytwopointsinthe
network.Theradiosdetectthered undantpathsandkeeponeconnectionalivefor
communications.IfthePrimaryconnectionfailsforanyreason,thesecondary
connectionisquicklytransitionedtoastatetoforwardpackets,allowingthene
tworkto
adaptitselftohandleproblemswithoutcustomerintervention.
RTSPusesactivecommunicationsbetweennetworkdevicestopropagatechangesinthe
networkandtocausetransitionstooccurmuchmorequickly.BecauseRTSPisanIEEE
