•
The new administrative weight will be communicated to the ATM switch
on the other end of the PNNI link via PNNI link messages.
•
Both SVCs and SPVCs from far end and near end ATM switch [n1]are
routed away from the PNNI link with high administrative weight.
•
This procedure interoperates with Marconi/Fore and GX 550 ATM
switches.
Integrated Link Management Interface (ILMI)
The integrated link management interface (ILMI) is a network management
function that supports bidirectional exchange of ATM interface parameters
between two connected ATM Interface Management Entities (IMEs). These
entities are an end user and a public or private network, or a public network
and a private network.
Based on an ATM Forum-defined interim specification, ILMI uses a limited
subset of Simple Network Management Protocol (SNMP) capabilities. ILMI
provides status information and statistics using SNMP and a MIB to provide
any ATM device with status and configuration information about the follow-
ing information available at its ATM interfaces:
•
Virtual path connections (VPCs)
•
Virtual channel connections (VCCs)
•
Registered ATM network prefixes
•
Registered ATM addresses
•
Registered services and capabilities
With System Software Release 6.5.0, VPI and VCI range negotiation is sup-
ported. It also determines the operational status of the logical port. ILMI is
supported for all ATM UNI 3.0 and ATM UNI 3.1 interfaces.
ILMI over PNNI
Overview
The ILMI over PNNI feature supports VPI and VCI range negotiation using
automatic configuration procedures.
The automatic configuration procedure is the ability to automatically config-
ure the following fields, found on the ATM PNNI Interface Configuration
window, based on the local VPI/VCI and the remote VPI/VCI ranges (VPI and
VCI range negotiation):
•
Min/Max SVC VPI
•
Min/Max SVC VCI
The PNNI ILMI Configuration window and PNNI ILMI Statistics window can
be accessed from the ATM PNNI Interface Configuration window. The PNNI
ILMI Configuration window is very similar to the ATM UNI ILMI Configura-
tion window.
