o address prefix
Support: L2,End
Default: None 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.
o block size
Support: End, type outbound
Default: 0 Value: 0-65536
The data link block size to be used for this prefix.
For an end system, the data link block size to be used for this
prefix. If the block size is set to the default, the manual block
size of the circuit will be used instead. This attribute is
supported only if the type characteristic is set to outbound.
o cost
Support: L2
Default: 20 Value: 1-63
Cost of reaching this address prefix over this circuit.
o data format
Support: L2
Default: Phase V Value: Phase IV (1) or Phase V (0)
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.
o 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.
o ISDN address
Support: L1,L2
Default: { } Value: Set of ISDN addresses
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.
o 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 the parent
reachable address entity. This attribute is supported only if the
type characteristic is set to outbound on broadcast circuits only.
A valid address is required here.
You can modify this characteristic only when the entity is
disabled.
o 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; or
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.
o metric type
Support: L2
Default: Internal Value: Internal, external
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.
o modem addresses
Support: L1,L2
Default: { } Value: Set of modem addresses
A set of full dial sequence that contains the address (PSTN or
ISDN) to which 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 modem address,
but not visible to Network Management, is a variable last
failure of type binary absolute time. This is valid only if
mapping is manual and the parent circuit entity's access time
is Modem DA.
o modem address prefix
Support: L1,L2
Default: L1,L2 Value: Address string
The address that is to be inserted to the beginning of the address
extracted from the NSAP address. This is valid only if mapping is
not manual and the parent circuit entity's access type is Modem
DA. It is used in conjunction with modem access suffix to form the
complete dial sequence.
o modem address suffix
Support: L1,L2
Default: L1,L2 Value: Address string
The address that is to be inserted to the end of the address
extracted from the NSAP address. This is valid only if mapping
is not manual and the parent circuit entity's access type is
Modem DA. It is used in conjunction with modem access prefix to
form the complete dial sequencence.
o permitted LAN address
Support: End
Default: { } Value: Set of LAN addresses
The set of LAN addresses corresponding to routers that are
permitted to be used for forwarding to this prefix. This
attribute is supported only if the type characteristic is set
to filter on broadcast circuits only. The default is an empty
set, and at least one LAN address is required.
o type
Support: L2,End
Default: Outbound Value: Inbound, outbound, or filter
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.
