PPP-IPCP Chassis Management Channel
The configurable parameters when initially defining a Chassis Management Channel are described below:
Name
This is a user-defined name for the management channel for ease in identifying the Chassis Management
Channels. The Name field is a character string up to 10 characters in length. Once the Chassis Management
Channel is created, the name can only be changed by deleting the channel and defining a new one.
IP Address (sysMgmtIpAddress)
The meaning of the IP address depends upon whether the Protocol Type is ppp-ipcp(1) or ppp-bcp(2). The
default Protocol Type is ppp-ipcp(1).
For ppp-ipcp(1) links, the IP address is the IP address of the PPP link’s remote end. As described for the T1/E1
management channels, the easiest configuration is with IP addresses in the same subnet as the cards in the
ForeFront chassis.
For ppp-bcp(2) links, the IP address is the local IP address, that is, the IP address on this end of the PPP link.

Figure 93 shows the IP addressing scheme for a PPP-IPCP Chassis Management Channel.
Direction
There are two directions for Port/TimeSlot pairs in a Chassis Management Channel: transmit (Tx) and
receive (Rx).
Tx refers to the port and time slot which transmits to the other card. It is simplex by definition.
Rx similarly refers to the port and time slot which receives data from the other end of the PPP link. Also sim-
plex by definition.
Port
There are 32 ports available between the cards in the ForeFront chassis. See section “TimeSlot” for additional
information since the Port and TimeSlot parameters operate in pairs.
