WAN DLCI
The in-band Frame Relay Management Channel WAN address is defined by the DLCI
(Data Link Connection Identifier). The WAN DLCI can be configured for a Dedicated
PVC, or as a Tunneled channel within a Payload PVC. During initial installation the
WAN DLCI can be set via the unit’s rear panel Configuration DIP Switches, Local
Console Port or Dial-In Console Port. Thereafter the DLCI can also be changed via in-
band management access.
Management
IP Addressing
NetPath 100 has special features for Network Service Providers (NSPs) who require
management access to the FSU to be isolated from the payload data. This isolated ac-
cess is provided either by NetPath 100’s dedicated network-facing management PVC
as shown in Figure 2-1 or by the Tunneled management channel on a network-facing
Payload PVC as shown in Figure 2-7.
Figure 2-7 Tunneled Management
Tunnel management is accomplished by a NetPath HUB (NetPath 1xx class unit) lo-
cated at a site which supports up to 48 PVCs connected to NetPath units located at re-
mote (spoke) sites. The HUB unit performs the routing and encapsulation function for
management channel messages going to and from the remote units. The HUB is con-
nected to the network management systems by a separate, dedicated group manage-
ment PVC.
