Frame Relay Port Configuration WAN Configuration
30.6 FRAME RELAY PORT CONFIGURATION
To configure frame relay WAN ports, you must first define the type and location of the WAN interface, optionally “set
up” a library of configuration settings, then apply those settings to the desired interface(s). The following examples
are designed to give you a small model of the steps necessary for a typical frame relay WAN interface specification.
To define the location and identity of a serial frame relay WAN port located at slot 5, port 1 with a speed rating of 45
million bits per second:
To define the location and identity of a High-Speed Serial Interface (HSSI) VC located at slot 4, port 1 with a DLC of
100:
Suppose you wish to set up a service profile called “profile1” that includes the following characteristics:
•
Committed burst value of 2 million and excessive burst value of 1 million
•
BECN active shaping at 65 frames
•
Committed information rate (CIR) of 20 million bits per second
•
Leave high-, low-, and medium-priority queue depths set to factory defaults
•
Random Early Discard (RED) disabled
•
RMON enabled
The command line necessary to set up a service profile with the above attributes would be as follows:
To assign the above service profile to the VC interface created earlier (slot 4, port 1):
30.7 POINT-TO-POINT PROTOCOL (PPP) OVERVIEW
Because of its ability to quickly and easily accommodate IP and IPX protocol traffic, Point-to-Point Protocol (PPP)
routing has become a very important aspect of WAN configuration. Using PPP, you can set up router-to-router,
host-to-router, and host-to-host connections.
Establishing a connection in a PPP environment requires that the following events take place:
•
The router initializing the PPP connection transmits Link Control Protocol (LCP) configuration and
test frames to the remote peer to set up the data link.
•
Once the connection has been established, the router which initiated the PPP connection transmits a
series of Network Control Protocol (NCP) frames necessary to configure one or more network-layer
protocols.
