CiscoNhrpErrorCode

• Base type Enumeration

This textual convention is used to indicate the error code associated with failures as part of NHRP protocol messages exchanged in an NBMA network. The values of the enumeration have been chosen to match the values returned as error codes in an NHRP packet. The enumeration can take the following values. -- This indicates that the responder couldn't process an -- extension in the NHRP packet. unrecogExtension(1) Unrecognized extension -- This indicates that an NHRP packet is being forwarded -- in a loop. loopDetected(3) NHRP loop detected -- This indicates that the NHS has refused the NHRP -- Registration/Resolution Request attempt for -- administrative reasons. adminProhibited(4) Administrative reasons -- This indicates that the NHS can't serve a station due to -- lack of resources. insufficientResources(5) Insufficient resources -- This indicates that the protocol address of interest is -- not reachable. addressUnreachable(6) Protocol address unreachable -- This indicates that a generic packet processing error has -- occurred(e.g.failed checksum, invalid protocol type, etc). protocolError(7) Protocol Error -- This indicates that the SDU size of the NHRP packet -- exceeds the MTU size of the NBMA network. sduSizeExceeded(8) NHRP SDU size exceeded -- This indicates that an extension in a packet is -- inappropriate for that packet type. invalidExtension(9) Inappropriate packet type -- This indicates that a client received an NHRP resolution -- reply for a request which it didn't make. invalidResReply(10) Invalid NHRP resolution reply received -- This indicates that a received packet failed an -- authentication test. authFailure(11) Authentication failure -- This indicates that there were absolutely no -- internetworking layer address to NBMA address bindings -- found in the responding NHS's cache. noAddressBinding(12) No address binding present -- This indicates that there were one or more -- internetworking layer address to NBMA address bindings -- found in the responding NHS's cache but none of them had -- the uniqueness bit set. bindingNotUnique(13) Address binding not unique -- This indicates that the client tried to register a -- protocol address to NBMA address binding with the -- uniqueness bit on and the protocol address already exists -- in the NHS's cache(with the uniqueness bit set). uniqueInternetworkAddrRegd(14) Protocol address(with uniqueness bit set) already in cache -- This indicates that the hop count of an NHRP packet has -- been exceeded. hopCountExceeded(15) Hop count exceeded -- This indicates an error that doesn't fall into one of the -- above categories. other(256) Other errors
