**Table 1** Description of the **display stack port brief** command output
Item	Description
Stack Port	Number of a stack port. unAllocated indicates that a service port has become a stack member port but has not been bound to a logical stack port.
PHY	Physical status of an interface: down: The interface is physically disabled. up: The interface is physically enabled. *down: The interface is manually shut down. down(r): Runts error continuously occurs on a stack port. down(c): There are CRC error packets on a stack port. down(l): A stack port repeatedly alternates between Up and Down states. down(m): The rate of the optical module installed in a stack member port is not the rate required by the member port.
Protocol	Link layer protocol status of the interface: down: A stack port does not receive stack link packets. up: A stack port can receive stack link detection packets.
InUti	Average inbound bandwidth usage of an interface within the last 300 seconds.
OutUti	Average outbound bandwidth usage within the last 300 seconds.
InErrors	Number of error packets received by an interface.
