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.
