Resolution
Multilayer Switch Feature Card 1 (MSFC1) does not contain Error-Correcting Code (ECC) memory protection. Therefore, the MSFC crashes if a parity error is detected. These error messages may occur in the following locations:
- On the console:
*** System received a Cache Parity Exception ***
signal= 0x14, code= 0xa405c428, context= 0x60dd1ee0
PC = 0x6025b2a8, Cause = 0x6420, Status Reg = 0x34008002
- In the crashinfo file recorded in the bootflash: or console:
Error: primary data cache, fields: data, SysAD
virtual addr 0x4B288202, physical addr(21:3) 0x288200, vAddr(14:12) 0x0000
virtual address corresponds to pcimem, cache word 0
Address: 0x4B288200 not in L1 Cache
Address: 0x4B288202 Can not be loaded into L1 Cach
If the parity errors occur more than once, the MSFC needs to be replaced. If the parity error happens only once, it could be a single event upset, and the MSFC should be monitored.
For more information on parity errors, refer to Processor Memory Parity Errors (PMPEs).
