How to access the file system of the slave MPU on an S series switch

18

For S series switches (except S1700 switches), you can run the dir command in the user view to check files of a switch. For an S series modular switch with dual MPUs, you can perform the following operations to check files on the master and slave MPUs: # Check files on the master MPU. dir flash:/ # Check files on the slave MPU. dir slave#flash:/
S series fixed switches and S12700 series switches support the flash memory. S7700&S9700&S9300 series switches support two storage devices, the flash and CF card (default storage device).
