Configuring a Device

## Configuring a Device

Device identity, capability and behavior are controlled by runtime parameters stored in the device PIB. To change device identity, capability or behavior you must alter a template PIB file, download it to the device and flash it into NVRAM. A template PIB can come from several sources but an excellent souce is the device, itself. Configuration changes then become a simple read, modify and write back operation.

Example 5.12. Read a PIB File

    # int6k  -i eth2 -p old.pib local
    eth2 00:B0:52:00:00:01 Read Parameters from Device
    eth2 00:B0:52:00:00:BE Read.

This example reads the PIB from the local device and writes it to a file. The toolkit has a growing number of programs designed to inspect and change pibfiles in various ways. Program modpib is one program that can be used for this purpose.

Example 5.13. Modify a PIB File

    # modpib old.pib -M 00:B0:52:00:BA:BE \
                     -N 00:11:22:33:44:55:66:77:88:99:AA:BB:CC:DD:EE:FF \
                     -D FF:EE:DD:CC:BB:AA:99:88:77:66:55:44:33:22:11:00 \
                     -S "Intergalactic Death Rays, Inc." \
                     -T "Global Spy Network" \
                     -U "Bedroom"

The example above edits identity parameters in PIB file, `old.pib`, recomputes the internal checksum and re-writes the file. The network identity parameters are MAC (`-M`), NMK (`-N`) and DAK (`-D`). The user identity parameters are MFG_HFID (`-S`), NET_HFID (`-T`) and USR_HFID (`-U`). The PIB file is ready for download and flash.

Program modpib is a safe way to edit a PIB file because it only change selected parameters. Use program setpib to edit other parameters if required.

Example 5.14. Save a PIB File

    # int6k  -i eth2 -P old.pib -C pib
    eth2 00:B0:52:00:00:01 Write Parameters to Device
    eth2 00:B0:52:00:00:BE Written.

This example writes the modified PIB file, `old.pib`, to the local device and commits it to NVRAM. Option `-P` writes the PIB file to the device instead of reading it from the device. Option `-C` with argument `pib` commits only the PIB, and not firmware, to NVRAM.
