ADDRESS PREFIX Support: L2, End Default: No default Value: Address prefix Address prefix to which this reachable address refers. You cannot modify this characteristic. This characteristic is set by means of an argument to the create command. The value of this characteristic derives from an argument to the create command. This characteristic is supported only if the owning circuit has type set to x25 da. COST Support: L2 Default: 20 Value: 1-63 Cost of reaching this address prefix over this circuit. DATA FORMAT Support: L2 Default: DECnet-Plus Value: Phase IV or DECnet-Plus The PDU data format to be used when forwarding data or error report NPDUs using this reachable address. This attribute is supported only if the type characteristic is set to outbound. You can modify this characteristic only when the entity is disabled. DTE ADDRESSES Support: End,L2 Default: No DTE addresses Value: set of DTE addresses A set of DTE addresses to which a call may be directed in order to reach an address that matches the address prefix of this reachable address. This characteristic is supported if the node is a level 2 router, where the owning circuit's characteristic type is one of the X.25 circuit types, and the reachable address's characteristic type is outbound. It is also supported by end nodes operating over an x25 da circuit. You can modify this characteristic only when the entity is disabled. ISDN ADDRESS Support: L1,L2 Default: A full set of E.164 ISDN network addresses that a call may be directed in order to reach a network number that matches the address prefix of the parent reachable address entity. Associated with each ISDN network address, but not visible to Network Management, is a variable last failure of type binary absolute time. This attribute is supported only if access type is ISDN DA. LAN ADDRESS Support: L2,End Default: 00-00-00-00-00-00 Value: id A single LAN address to which an NPDU can be directed in order to reach an address that matches the address prefix of this reachable address. This characteristic is supported only if the owning circuit's characteristic type is csma-cd, and the reachable address's characteristic type is outbound. You can modify this characteristic only when the entity is disabled. MAPPING Support: End,L2 Default: X.121 Value: Manual or X.121 Type of mapping used to determine the SNPA address to which a call should be placed for this address prefix. You can modify this characteristic only when the entity is disabled. If the circuit is a broadcast circuit, this attribute must have the value manual. MANUAL - The mapping uses the set of addresses in the characteristic dte addresses or the address in the characteristic LAN address. X.121 - The mapping uses the X.121 address extraction algorithm. This characteristic is supported only if either of the following conditions is satisfied: o The node is a level 2 router or an end node, and the owning circuit's characteristic type is one of the X.25 circuit types. o The node is a level 2 router, the owning circuit's characteristic type is csma-cd, and the reachable address's characteristic type is outbound. METRIC TYPE Support: L2 Default: The metric type of the cost metric for the circuits. If internal, the I/E bit for the metric in the Prefix Neighbors option of L2 LSPs is set to 0, otherwise external is set to 1. TYPE Support: L2,End Default: Outbound Value: see below Type of the reachable address. You can modify this characteristic only when the entity is disabled. INBOUND - For L2 only, the address prefix corresponds to a Phase IV area that is reachable through this node and circuit by inbound traffic. OUTBOUND - The address prefix is in an external domain that is reachable over this circuit by outbound traffic. FILTER - The address prefix defines a set of addresses that should be reached via the set of routers listed in the permitted LAN address characteristic.
