Flash Memory
Flash memory is a non-volatile, reprogrammable, memory storage device for
router software releases, allowing upgrades to be remotely loaded from any
WAN or LAN port. Flash memory is also used to store other types of data such
as patches, logs and configurations.
Testing flash memory
There are several ways to check that onboard flash memory is installed and
operating correctly. First, check that the router has recognised the flash
memory by displaying system information (Figure 1-7 on page -27) with the
command:
show system
The second part of the display shows the types and sizes of memory installed
in the router. If the flash memory size is lower than expected, then the router’s
boot process has not correctly detected or recognised the flash memory’s
presence. If recognition fails, contact your authorised Allied Telesyn distributor
or reseller.
If the flash is recognised, display flash memory size, device type, and location
with the command:
show flash physical
A typical display is shown in Figure 1-8 on page -27.
Lastly, check the Flash File System (FFS) to ensure that it has successfully
formatted the flash. Use the command:
show file
