Solution

A TOE_ERR_MEM_READ error is reported whenever there is a transient memory error in TOE for LU, which is used for statistics collection. It is related to a transient hardware issue and there could be different reasons for a TOE ERROR to be reported, such as an ifetch error and memory error.

 

To clear this error, use the following command:

clear chassis fpc errors fpc-slot <fpc_slot_number> all

If the error reappears even after executing the clear command, reset the FPC by using the following command:

request chassis fpc slot 0 offline|online
