WAN Management
IP Address
NetPath 100 utilizes one IP Address on the dedicated, network-facing Wide Area Net-
work (WAN) management channel. This address is embedded within the various com-
munications protocol stacks used for SNMP, Telnet and PPP. The unit’s WAN
Management IP Address may be automatically learned from the first message received
on the management PVC, or it can be set via the local or remote Console Port.
When optioned with ISDN, NetPath 100 can have several communications paths that
allow the management channel to connect to the frame relay network in different plac-
es. Each of these connection points could result in the management PVC routing
through different IP sub-nets to reach the Network Control Center, or it may be desir-
able to have the NetPath 100 appear as a logically different object in the SNMP man-
ager, especially if static routing and dedicated backup ports are utilized. The setting/
learning of these additional IP Addresses is described in detail in Section 4, “Config-
uration,” in this manual.
NetPath 100 will retain in Non-Volatile Memory (NVM), a separate WAN IP Address
for each connection point. All communications via OOB PPP (Out-Of-Band Point-to-
Point Protocol) will utilize whatever IP Address is in effect depending on how the unit
is currently connected to the network. There are several options for establishing the
WAN IP Address within the NetPath 100.
When the unit is shipped from the factory or when NVM is cleared on initial installa-
tion, the WAN IP Address for each connection point is set to 000.000.000.000, which
indicates no address is known.
The WAN IP Address to be used on the T1 link is automatically “learned” from the
first valid IP message received over the unit’s management PVC. Learning will take
place as long as the value of the WAN IP Address in NVM is 000.000.000.000. Once
the IP Address is set or learned it is retained and used until the NVM is cleared or an-
other address is manually set.
Software
Download
The NetPath 100 system software (firmware) is stored in flash memory. A new version
of the software can be downloaded to the unit for software upgrade, or for restoration
in the event an error is detected in the flash storage.
A description of the software download process is provided in Section 5, “Diagnos-
tics,” of this manual.
Trap Reporting
The NetPath 100 provides an MIB which includes standard MIB-II groups and also
contains a Private MIB Extension which supports the issuance of unique Traps. Traps
are issued either in-band or dial-out (out-of-band) via the on-board modem, depending
on the specific fault detected.
Section 5 Diagnostics of this manual lists the MIB objects and the Trap reporting path
for each.
