Usage
TheCoSsettingstabletakesindividualclassofservicefeaturesanddisplaysthemasbelongingto
aCoSentry. Essentially,itisusedforCoSfeatureassignment.Eachclassofserviceentryconsists
ofanindex,802.1ppriority,anoptionalToSvalue,andanIRLreference.
•CoSIndex
Indexesareuniqueidentifiers
foreachCoSsetting.CoSindexes0through7arecreatedby
defaultandmappeddirectlyto802.1ppriorityforbackwardscompatibility.Theseentries
cannotberemoved,and802.1ppriorityvaluescannotbechanged.WhenCoSisenabled,
indexesareassigned.Upto256CoSindexesorentriescanbe
configured.
•Priority
802.1pprioritycanbeappliedperCoSindex.ForeachnewCoSindexcreated,theuserhasthe
optiontoassignan802.1ppriorityvalue0to7fortheclassofservice.CoSindexes0through7
mapdirectlyto802.1pprioritiesandcannotbechangedastheyexist
forbackward
compatibility.
•ToS
Thisvaluecan besetperclassofservice,butisnotrequired.Whenaframeisassignedtoa
classofserviceforwhichthisvalueisconfigured,theToSfieldoftheincomingIPpacketwill
beoverwrittentotheuser‐definedvalue.Allbut
thelasttwobitsoftheToSfieldare
rewritable.ToScanbesetforCoSindexes0through7.
•IRLReference
TheCoSIRLreferencefieldisoptional,asratelimitsarenotrequired.TheIRLreferencedoes
notassignaninboundratelimitbutpointstotheCoSIRLReference
