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:

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 |
