The test software will read the file allocation table and display a list of free
sectors. Sectors can be tested as single sectors or as a range. The test will consist
of a write/read/verify cycle.
To stop the test, use the command:
DISABLE CFLASH TEST
To display the testing process while a test is in process, enter:
SHOW CFLASH TEST
Figure 13 on page 33 shows a sample output.
Figure 13: Output from the SHOW CFLASH TEST command, when a test is running.
If used when testing is not active, the previous command displays blank
cluster ranges on a compact flash card (Figure 12 on page 32).
Error messages are displayed when a file write fails. Failure could be due to the
card being removed or an error in the card.
Content Addressable Memory (CAM)
AT-9800 Series switches ship with 40 k-entries of CAM, as standard. This
memory is divided into three fixed allocations:
• 8 k for MAC address tables
•4 k for VLAN entries
• 28 k for all other L2/L3 tables (for example, IP route entries)
CAM can be expanded through the purchase and installation of lineCAM.
LineCAM is a 192 k-entry plug-in module that extends the switch’s Layer 2/
Layer 3 forwarding database from 40 k to 232 k. One lineCAM module can be
installed in each AT-9800 series switch.
When lineCAM is installed, the memory allocations are:
• 8 k for MAC address tables
•4 k for VLAN entries
• 220 k for all other L2/L3 tables
LineCAM can be ordered as a pre-installed item when purchasing a switch, or
can be purchased separately.
