42 © 2000, Cisco Systems, Inc. CMPLS 1.0– Appendix A-42 RPM IOS Anomalies LAN interfaces numbered x/y/z: x is RPM’s slot number y is 1 or 2, and is backcard shelf z is 1..4, and is the port number Internal OC-3 is called “switch” interface IOS file can be kept on PXM harddisk

43 © 2000, Cisco Systems, Inc. CMPLS 1.0– Appendix A-43 RPM Initial Setup Configuration Steps 1. Verify name of IOS file on PXM HD cd RPM, ls 2. Refer to IOS in RPM boot command boot system c:iosname 3. enable internal OC-3 interface no shutdown

44 © 2000, Cisco Systems, Inc. CMPLS 1.0– Appendix A-44 RPM Initial Setup Configuration Steps 4. Configure enable password enable secret xyz configure telnet password line vty 0 4 (and others) 6. Set hostname of router hostname fredrpm1

45 © 2000, Cisco Systems, Inc. CMPLS 1.0– Appendix A-45 RPM Initial Setup Configuration Steps 7. Save configuration and boot RPM copy run start, reload 8. Not required yet, but good idea: resource partitioning rpmrscprtn PAR ….
