Local fault event detection and counters
1
Limits and restrictions
Current implementation with this feature has the following limitations:
• Works only on a 10GbE LAN interface. Information for ports in a WAN interface at the time of
inquiry is not displayed. Information for a port that does not belong to 10 GbE module is not
displayed.
• In a Management Module switchover state, the remote fault notification counts and detection
time are maintained.
• The RFN counts of a port only reset to zero in the following conditions:
• At slot initialization (power on).
• When the clear remote-fault command is enabled on 10 GbE LAN interface.
• When configuring a 10GbE port into WAN mode.
Local fault event detection and counters
Local fault event detection and counters are enabled for ports on 10GbE LAN physical interfaces
when link fault signaling is enabled on the interface. If both local fault and remote fault events are
detected on the same interface, then the remote fault event is reported.
If a port is down because of a local fault event, then a syslog message is generated to inform you of
this event. The syslog message will display “(local fault)” in the dynamic log buffer. For more
information on local fault syslog messages, refer to the Multi-Service IronWare Administration
Guide. The local fault event is also indicated in the show interface command. In the show interface
command, the reason is displayed as “(local fault)”. For more information on the show interface
command, refer to the Multi-Service IronWare Administration Guide.
Displaying and clearing local fault counters
To display local fault counters on 10GbE LAN physical interface, enter the following command.
The example above displays local fault counters for ports 2/1 and 2/2 in LAN physical mode.
To clear local fault counters on a 10 GbE LAN physical interface, enter the following command.
The example above displays ports 2/1 and 2/2 cleared for local-fault statistics.
Syntax: show or clear local [ethernet [to ] | slot ]
You can display information for local fault counters in a Brocade device by using the show
local-fault command without options,
Or use the ethernet option to limit the display to a single ethernet port.
Brocade# show local-fault ethernet 2/1 to 2/2

Brocade# clear local ethernet 2/1 to 2/2
Local-fault stats for port 2/1 is cleared.
Local-fault stats for port 2/2 is cleared.
