Cisco MGX Route Processor Module (RPM-PR) Installation and Configuration Guide
Release 2.1, Part Number 78-12510-02 Rev. C1, August 31, 2004
Chapter 5 Configuring the MGX RPM-PR
Booting the RPM-PR
Back Card Bay and Interface Port Numbers
This section describes how to identify the back card bay and interface port numbers on the RPM-PR for
all back card interface types.
Physical port addresses specify the physical location of each interface port, regardless of the type, on the
RPM-PR. In the RPM-PR, this address is composed of a two-part number in the form
<interface bay number/interface port number>, as follows:
• <interface bay number> identifies the bay in which the back card is installed, either upper (1) or
lower (2) bay.
• <interface port number> identifies the interface port(s) on the back card. FE cards have one
interface number. 4E/B cards have four numbered interfaces.
For example, the following command specifies interface port 1 of the upper Ethernet back card in the
RPM-PR. You need to enter this information to select a specific port on a back card or ATM interface.
Router(config)#interface fastEthernet 1/1
Also, you can identify interface ports by checking the bay/interface port location on the body of the
RPM-PR or by using show commands to display information about a specific interface or all interfaces
in the RPM-PR.
Configuring IP Addresses and Starting Ethernet Interfaces
The following steps describe how to configure IP address on the 4E/B Ethernet and the FE Fast Ethernet
interfaces and how to start them up. Press Return after each step unless otherwise noted.
Note RPM-PR no longer supports the MGX-RJ45-4E Ethernet interface back card. You must use an
MGX-RJ45-4E/B Ethernet card with Release 2.1 or later.
Step 1 At the privileged-level prompt, enter the command global configuration mode as follows:
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 2 To specify the interface to be configured, enter the following interface subcommand at the prompt.
interface <ethernet | fastethernet> <bay>/<port>
Note The 4E/B interfaces are numbered 1, 2, 3, 4, not 0, 1, 2, 3 as in other IOS platforms.
This example is for the upper (1) Ethernet back card in the RPM-PR in slot 11 of the switch. In this
example, we configure a Fast Ethernet interface. The procedure you use to configure an Ethernet
interface is identical except for specifying the Ethernet interface type.
Parameter Description
<ethernet | fastethernet> Interface type to be configured.
<bay> Back card location; 1=upper and 2=lower back card
<port> Port number on the back card
