Models 2616RC, 3096RC & 3196RC Admin Reference Guide 11 • In-band management
Overview
This chapter describes how to configure in-band management channels. The “Introduction” section describes
the architecture and use of in-band management channels. Succeeding sections describe the three types of in-
band management channels (each section includes examples that will help you understand and use in-band
management channels in your network system).
The first type of in-band management channel is described in section “Defining a T1/E1 Management Chan-
nel” on page 154. The following examples of T1/E1 management channels are included:
• Using a Frame Relay channel over the T1/E1 port
• Creating a bridged PPP channel over T1/E1
• Implementing a routed PPP channel
The second type is described in section “Defining a Chassis (H.110) Management Channel” on page 160. The
following two examples are included:
• A routed PPP (IPCP) chassis management channel
• A bridged PPP (BCP) chassis management channel
The third and last type is described in section “Defining a G.SHDSL Management Channel” on page 167.
The following examples connect via a Patton Model 3086 over a G.SHDSL link in two configurations:
• A bridged PPP (BCP) management channel
• A routed PPP (IPCP) in-band channel
Introduction
The Models 3096RC G.SHDSL, 3196RC iDSL, and 2616RC T1/E1 T-DACs offer in-band management
over Frame Relay or PPP (point-to-point protocol). Management channels may be created over a T1/E1 WAN
port, a G.SHDSL WAN port, or the Chassis Management Channels. The remote management channel is for
access from a remote management station via the T1/E1 or G.SHDSL WAN port into the T-DAC. The Chas-
sis Management Channels are management links between cards within the same ForeFront chassis.
By using a combination of remote management channels and Chassis Management Channels, all the cards in
one chassis and multiple chassis can be managed via one T1/E1 or G.SHDSL WAN link from a remote man-
agement station, which may simply be a PC with a standard browser like Netscape or Internet Explorer.
The remote management channels may be configured for either Frame Relay or PPP using a single or multiple
DS0 time slots in the T1/E1 or G.SHDSL WAN port. Each Chassis Management Channel uses one time slot in
each direction. Further details are provided below in the section describing how to define a Chassis
Management Channel.
Figure 82 is a graphical example with the management station accessing the ForeFront chassis through a T1/E1
or G.SHDSL WAN port via a TDM network. T-DAC_2 and T-DAC_3 have in-band management paths with
Chassis Management Channels in a star topology. T-DAC_1 is the hub of the star.
