Enabling automatic forwarding path check
When the switch is operating, traffic forwarding exceptions might occur due to hardware failures or
other reasons. You can enable automatic forwarding path check so that the switch gives prompts when
a forwarding exception occurs. According to the prompts, you can troubleshoot the problem.
To enable automatic forwarding path check:

Enabled by default.
Above the configuration, if a forwarding exception occurs, the switch gives prompts, for example:
%Aug 20 14:55:54:973 2010 H3C DIAG/3/ERROR: -Slot=8; Forwarding fault: slot 5 to slot 8
%Aug 20 14:55:55:084 2010 H3C DIAG/3/ERROR: -Slot=6; Forwarding fault: slot 6 to slot 6
The output shows that a forwarding exception exists between the cards in slot 8 and slot 5, and an
exception in internal data forwarding exists on the card in slot 6.
Enabling port recovery for the switch
On an S12518 switch, if the switching fabric module LST1SF18B1 is configured and a 8-port or 32-port
10GE optical Ethernet interface card is installed in any of slots 16 to 19, it might cause some ports on
some interface cards unavailable.
