mscRtgRsReasonForNoRoute
Module: Nortel-MsCarrier-MscPassport-PorsVcMIB
OID (symbolic): Nortel-MsCarrier-MscPassport-PorsVcMIB::mscRtgRsReasonForNoRoute
OID (numeric): 1.3.6.1.4.1.562.36.2.1.40.2.10.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This attribute indicates the reason for which a route was not selected by RouteSelector.
If the route was selected then reasonForNoRoute has a value of none.
If the destination in the form of ASCII name was specified (see destination) and the name of node is too long (more than 12 characters) then reasonForNoRoute has a value of destinationNameTooLong. Check and correct node name in the destination attribute.
If the destination was not specified, that is destination is blank, then reasonForNoRoute has a value of destinationNotSpecified. Destination attribute should not be blank.
If the destination in the form of ASCII name was specified (see destination) and the name of node cannot be found in topological database then reasonForNoRoute has a value of unknownDestinationName. Check and correct node name in the destination attribute. If it is correct then this node does not appear in local topological database as this node may lie across the topology region or cluster boundary.
If the destination cannot be found in the topological database or cannot be reached through any gateway node then reasonForNoRoute has a value of unknownDestination. Ensure the destination specified in destination attribute resides in the topology region, or can be reached through a Routing Gateway. That is, at least one reachable address provisioned under a Trunk Address component representing a gateway link can reach the destination NSAP address.
If the destination was specified using an incorrect format (see destination) then reasonForNoRoute has a value of incorrectDestination. Use the correct format for destination attribute.
If there is no physical connectivity to the destination or gateway node, or number of hops to such node exceeds a limit of 20 hops, or a route to such node cannot satisfy all the parameters in the route request data then reasonForNoRoute has a value of attributeNotMet. Set operationMode to manual and issue d rtg rs command and inspect attributeNotMet to determine which attribute could not be satisfied.
If the route to the destination could not be selected for some internal reason then reasonForNoRoute has a value of internalReason. A Software Alarm generated in association with this situation should be reported to Nortel Networks technical support.
If the route to the destination could not be selected because of profile reference problem then reasonForNoRoute has a value of attributeProfileProblem.
If the route to the destination could not be selected because of manual path reference problem then reasonForNoRoute has a value of manualPathIndexProblem.
The following values of reasonForNoRoute are no longer generated: routeCostTooMuch, routeDelayTooMuch, incorrectDestinationEndPoint, and sameNode.
What is mscRtgRsReasonForNoRoute?
Reports why RouteSelector failed to find a route the last time it tried, from a malformed or unknown destination name, to no physical connectivity, to an internal error, or 'none' if a route was successfully selected; an admin reads this value first when a connection isn't coming up, since it points directly at which specific input, destination format, reachability, or requested attributes, to check.
