Hi, Moti, Do you mean we
should specify which lower-layer entity should be used to transmit ANCP message
by using ancpAnSessionConfigRelatedEntity? If yes, then what is
the difference between ancpAnSessionConfigRelatedInterface and
ancpAnSessionConfigRelatedEntity, as shown below? I think they both specify an
interface in case of Ethernet, it is duplicated. ……
(taken from draft-ietf-ancp-mib-an-04
) ancpAnSessionConfigRelatedInterface
InterfaceIndex, ancpAnSessionConfigRelatedEntity
RowPointer,
ancpAnSessionConfigSvid
VlanIdOrNone, …… BTW, when creating
an ANCP session, we need to specify the IP addr of the ANCP server ? BRAS; that
would be sufficient; what is the point to specify the lower-layer entity? The AN
should choose the lower-layer entity itself. Thanks! Best Regards James 发件人: Moti
Morgenstern [mailto:Moti.Morgenstern at ecitele.com] Hi James, The ANCP session is
always associated with some lower-layer entity, e.g., a virtual bridge port, an
ATM VCC, Ethernet interface, etc. Notice that each one
of the “lower-layer” entities listed here has a different identifier-type. The
bridge port has a port id, the VCC is identified by (ifIndex, VPI, VCI) and the
Ethernet interface has a unique ifIndex value. So, the value in
ancpAnSessionConfigRelatedEntity is the SNMP Object ID that uniquely identifies
the associated lower-layer entity. The format is
therefore, as you understand, an index into another SNMP table. Regards, Moti Morgenstern From: ancp-bounces at ietf.org

Huang Hi, all, I have some questions about the
implementation of ANCP MIB item ancpAnSessionConfigRelatedEntity; can anybody
give me some idea? Thanks in advance! http://tools.ietf.org/html/draft-ietf-ancp-mib-an-04 ancpAnSessionConfigRelatedEntity

DESCRIPTION
"This object contains the name of an object instance
uniquely identifying a lower layer entity associated
with this session. For example, in the case where
the session is associated with an ATM VCC, this object
might be set to an object identifier uniquely identifying
that VCC (e.g., an object instance in atmVclTable).
If unused, this object MUST have the value zeroDotZero.
The value of this object is persistent."
DEFVAL { zeroDotZero }
::= { ancpAnSessionConfigEntry 16 } Question: 1.
“a
lower layer entity associated with this session” What
is the association between a lower layer entity and an ANCP session? Is it
associated with partition id? What
is the application scenario for this? 2.
what is the format of the name/identifier "Access-Node-Identifier
atm slot/port:vpi.vci", which is defined in TR-101, or an index, i.e. an
index of the atmVclTable? Best Regards James |
