Handling Proxy Address Resolution Protocol (ARP) for DSL Cards
When configuring a Hotwire DSLAM system, the user can choose to have the
DSL cards Proxy ARP for the remote 5446 Remote Termination Units (RTUs).
This configuration is attractive in large networks because it simplifies the
configuration needed on the router. In certain network configurations however,
the use of Proxy ARP on the DSL cards causes OpenView to log a major event.
This occurs when OpenView or NetView receives the same IP address from two
different MAC addresses.
By default, the OpenView system logs and displays all events. However, the user
can filter out certain events. This is desirable, because it prevents the Event
Browser dialog from becoming bogged with extraneous error messages.
To filter out these events, see the subject
Filtering Events in the OpenView or
Netview user documentation.
Obtaining the Identity of Devices and Interfaces
When you request an identity for a device or device interface, a description is
displayed, which include information such as the model number, device or
interface up time, physical location of the device, and so forth.
The procedures that follow describe how to:
H Obtain the identity of a device from OpenView
H Obtain the identity of a device from the Device Display
H Obtain the identity of MCC, DSL, and NAM cards from the Device Display
H Obtain the identity of endpoints connected to a DSL interface from the
Device Display
