One would think that Cisco could do with these boxes what they do (or at least
did) with the 12K; at least on GRP, up through 12.0(32)S12, the various ROMMONs
and other firmware pieces are in the IOS image, and using 'service upgrade
{rommon|mbus-agent-rom|fabric-loader|all}' is available to make it automatic.
And that includes those pieces for the RP itself.
Oh, but that's a different BU, no? Or would the images just get too crazy
large (sounds like ASR is doing that if images are in the hundreds of megs like
I seem to remember was posted a week or two ago) for other platforms?
On ancient Catalyst 8500 the FPGA bitstreams were separately packaged, too. I
don't have one running right now to check if the other firmware for the
linecards that needed firmware were included in the IOS image or not.
Same thing for Catalyst 5500, firmware for linecards that needed it (ATM
modules, the nine-port Gigabit EtherChannel, and the RSM/RSFC) were packaged
separately.
The 12K way has me spoiled, to put it mildly. If I need to put in another LC,
and that LC happens to have old ROMMON or fabloader firmware, it just gets
upgraded and you keep on trucking when the card is inserted, if the firmware is
appropriate for the card. Of course, there are other niggles with 12K, but I
digress. And I don't have anything newer than Engine 2, so Cisco might have
changed things for Engines 3 and up for all I know.
