Command History

Usage Guidelines This command resets all accumulated operational statistics for the specified interface. Operational

statistics can include counters for packets received and transmitted, collisions, octets, multicast packets,

dropped and unsupported protocol, exception status IOCBs (such as LIP reset aborts, port unavailable

or logged out, DMA errors, port configuration changed, command timeout, data overrun, write or read

data underrun, and queue full), Fibre Channel errors, and other general events.

Clear counters before beginning a troubleshooting session, so you can quickly identify the counters that

are changing.

Examples The following example clears all accumulated operational statistics counters for the Fibre Channel

interface fc1.
