Performance Route Processor Installation and Configuration Guide
OL-11656-01
Note Output from the show version command on a PRP-2 card running on software
releases prior to 12.0(30)S may display some incorrect information. This is only
a display issue and it occurs because the software does not recognize some of the
hardware on the card. This does not affect the functionality of the PRP-2. For
example, the following is incorrect output from the show version command on
release 12.0(22)S:
cisco 12406/PRP (MPC7450) processor (revision 0x00) with 1048576K
bytes of memory. unknown CPU at 598Mhz, Rev 1.1, 256KB L2, 2048KB L3
Cache
The output from a later software release would be as follows:
cisco 12406/PRP (MPC7457) processor (revision 0x00) with 1048576K
bytes of memory. MPC7457 CPU at 1263Mhz, Rev 1.1, 512KB L2, 2048KB L3
Cache
Hardware Revision Requirements
To ensure compatibility with the software, the PRP should have a specific
hardware revision level or greater. The hardware revision number is printed on a
label affixed to the component side of the card. The hardware revision number can
also be displayed using the show diags slot-number command.
The minimum hardware revision number for the PRP (Product Number PRP-1=)
is 73-5936-05, Rev. A0. The minimum hardware revision number for the PRP-2
(Product Number PRP-2=) is 73-8812-04 Rev. A0.
Note Output from the show diags command on a PRP-2 card running on software
releases prior to 12.0(30)S may incorrectly indicate “PRP-1+” or “FRU number
not known” as the installed FRU.
