Configuring Interfaces on the PRP-3
Configuring the Auxiliary Interface
The auxiliary port on the PRP is a DTE, RJ-45 plug for connecting a modem or other DCE device (such
as a CSU/DSU or another router) to the router. The port is labeled Aux, as shown in Figure 15. The
asynchronous auxiliary port supports hardware flow control and modem control. Table 14 lists the pinout
for this port.
Configuring Interfaces on the PRP-3
This section includes configuration and connection information through the Ethernet, console, and
through the terminal server on the PRP-3. The following sections describe three ways to connect to a
DSC or DSDRSC:
• Establishing a Connection Through the Console Port, page 48
• Establishing a Connection Through a Terminal Server, page 50
• Establishing a Connection Through the Management Ethernet Interface, page 52
Establishing a Connection Through the Console Port
To connect to the router through the console port, perform the following procedure.
SUMMARY STEPS
1. Identify the active RP or DRP.
2. Connect a terminal to the Console port of the active RP or DRP.
3. Start the terminal emulation program.
4. Press Enter.
5. Log in to the router.
