During my testing of the discovery of unnumbered serial interfaces for
I compiled the following
list of requirements:
Requirements for the discovery of unnumbered serial interfaces:
1) Netmon must be running with the -u flag (default for V6.0)
2) SNMP configuration must include the proper community names to allow
to read the MIB on the routers on each end of the serial interface.
3) All components of the connection must be managed (routers, serial
and networks involved).
4) Name resolution must be configured to allow netmon to resolve all names
5) If all components are not found during initial discovery, it may be
to demandpoll each router to allow netmon to analyze the information and
ipmap with the information necessary to display the connection correctly**.

Subject: [NV-L] IfSpeed/hasSerial fields and unnumbered interfaces
My customer has the following enviroment: AIX 4.3.3, NetView 6.0 and
Cisco Routers mod. 7500 IOS 11.2. The routers have interfaces of the type:
fddi, atm, ethernet and serial. IP addresses are defined only to the
ethernet interface. The router network is discovered through a seed file
that contain just the routers IP addresses, there is not a DNS.
He is testing the new features in NetView 6.0 and noticed:
1.the new fields IfSpeed and hasSerial are not in the object information
of the router Cisco.
2.it seems that there is not support (as suppose to be) for the
interfaces, indeed are discovered just the ethenet interfaces of the
router. (netmon has the flag -u) . In Tools--->Display Object
Information you can verify that is reported only the information
regarding the ethernet interfaces. Using the MIB Browser you can read
the IfDescr, Iftype, IfAdminStatus and IfOperStatus and understand
that NetView is missing something in the discovery phase.
Has anyone ecountered the same problems before ?. Any idea ?.
