Table 13-7 Display of the number of sent, received, and discarded packets for ports
Item Meaning Displayed information
Port Counts Number of target ports --
Port Port Interface port number
Name Port name Displays the name assigned to a port.
Status Port state up: Active (normal operating state).
down: Active (a line failure has occurred).
inact: The port is inactive#
The following can cause a port to become
inactive:
- The inactivate command, which stops
operation
- The standby link functionality of link aggregation
- The BPDU guard functionality of a Spanning
Tree Protocol
- The storm control functionality
- Detection of a unidirectional link failure by the
UDLD functionality
- The L2 loop detection functionality
dis: Operation has been stopped by using the
shutdown or schedule-power-control
shutdown interface configuration command.
T/R Receiving/sending Tx: Sending
Rx: Receiving
All packets Number of all packets (including error packets)
Multicast Number of multicast packets
Broadcast Number of broadcast packets
Discard Number of discarded packets
#: inact is cleared in the following conditions:
 The port is restored by execution of the
activate command.
Due to the BPDU guard functionality of the Spanning Tree Protocol
The storm control functionality
Detection of a unidirectional link failure by the UDLD functionality
The L2 loop detection functionality.(The automatic restoration functionality can be
also used for recovery.)
 The standby link functionality of link aggregation makes the standby port the active
port.
