Hello Niko,
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
to ip

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 ?.
