Configuring Node Aliases
ThenodealiasfeatureenablesadministratorstodeterminetheMACaddressandlocationofa
givenend‐station(ornode)usingthenode’sLayer3aliasinformation(IPaddress)asakey.With
thismethod,itispossibletodeterminethat,forinstance,IPaddress123.145.2.23islocatedon
