Specify the slot number for a StorageWorks Core switch.
For all other switches this operand is not required. The slot
number must be followed by a slash ( / ) and the port
number, so that each port is represented by both slot
number (1 through 4, or 7 through 10), and port number
(0 through 15).
The StorageWorks Core switch has a total of 1–10 slots.
Slot number 5 and 6 are control processor cards, and slot
1 through 4, and 7 through 10, are port cards. On each
port card, there are 16 ports counted from the bottom, 0 to
15.
Specify a port number. Valid values for port number vary
depending on the switch type. This operand is required.
Specify the monitor number you want to clear. Monitor
numbers are defined when you create the monitor on a
port. This operand is optional. If not specified, all
monitors's counters on the port will be cleared.
