Inband Management
Inband to Avidia
The Avidia system automatically creates two dedicated management PVCs to Megabit Modems
700F, 600F, and 500L. SNMP requests are sent to the Avidia system from an NMS/EMS. When
the Avidia system receives the SNMP request, it either responds or forwards depending on
the value of the community string (see the
"Determining IP Addressing and Subnet Masks" on page 42
system for inband management.
Inband to Modems
With the inband management of modems, SNMP requests are made from the NMS/EMS over
the xDSL port connection to the modem. The Avidia system acts as a proxy agent for the SNMP
request to the modem. The SNMP request from the NMS/EMS to the Avidia system
must include:
•
the IP address for the Avidia system
•
an Object ID (OID) for the modem (rather than the OID for the Avidia system)
•
the slot and port of the channel card where the modem is attached appended to the
community string, (for example, public:4.2)
The modified community string enables the Avidia system to recognize that the request is
destined for a specific modem, and to forward the request to the appropriate channel
card port.
For modems, inband management provides the ability to:
•
configure or change WAN, LAN, and system parameters
•
collect statistics (status and performance history from both the LAN and WAN interfaces)
•
troubleshoot
