356 Administering Advanced Performance Monitoring
Specifies the slot number for a 4/256 SAN Director director. 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 Directors have a total of 10 slots. Slot numbers 5 and 6 are control
processor blades; slots 1 through 4 and 7 through 10 are port blades. For
16-port blades, there are 16 ports, counted from the bottom, numbered 0 to 15.
For 32-port blades, there are 32 ports numbered 0 to 31.
Specifies a port number. Valid values for port number vary, depending on the
switch type. This operand is required.
Specifies an interval in seconds. The interval must be greater than or equal to
five seconds. For end-to-end monitoring, the Tx and Rx counts are measured in
bytes. This operand is optional.
