With a Model BLN router, for example, information similar to the following
appears, with one
wfHwEntry.wfHwDiagPromSource line for each slot:
wfHwEntry.wfHwDiagPromSource.2 =
"/harpdiag.rel/v4.00/wf.pj/harpoon.ss/image.p/frediag.exe"
wfHwEntry.wfHwDiagPromSource.3 =
"/harpdiag.rel/v4.00/wf.pj/harpoon.ss/image.p/frediag.exe"
wfHwEntry.wfHwDiagPromSource.4 =
"/harpdiag.rel/v4.00/wf.pj/harpoon.ss/image.p/frediag.exe"
wfHwEntry.wfHwDiagPromSource.5 =
"/harpdiag.rel/v4.00/wf.pj/harpoon.ss/image.p/frediag.exe"
Each line of response to the command specifies
• A slot number (for example, “
wfHwEntry.wfHwDiagPromSource.
2
” identifies
slot 2)
• A path name that contains the version number of the image stored in a
diagnostics PROM (for example,
"/harpdiag.rel/v4.00/wf.pj/
harpoon.ss/image.p/frediag.exe"
identifies the “v4.00” (Version 4.0)
diagnostics PROM image frediag.exe in slot 2).
Using the prom Command
To upgrade the PROMs:
1.
Insert a flash card with contiguous free space sufficient to accommodate
the PROM images you want to use as source files for upgrading boot or
diagnostic PROMs on one or more slots.
To determine the amount of contiguous free space, display the directory of the
flash volume by entering the following command from the Technician
Interface prompt:
dir
<volume_no.> :
Note:
Before upgrading any router software, always save copies of the
original configuration file and boot image as a safeguard, in case you
encounter problems during the procedure.
