Parameters
slot slot-number: Clears the IP packet statistics on a specified IRF member switch. The slot-number
argument specifies the ID of an IRF member switch. The value range for the argument depends on the

display irf command. On a standalone device, the slot-number argument specifies the ID of the device.
