Description
•

•
H—Half duplex.
•

Link type of the interface:
•
A—Access.
•
H—Hybrid.
•
T—Trunk.
Port VLAN ID.
Cause for the physical link state of an interface to be DOWN:
•
Administratively—The port is manually shut down by using the
shutdown command. To restore the physical state of the
interface, use the undo shutdown command.
•
DOWN ( Link-Aggregation interface down )—When an
aggregate interface is shut down, the physical state of all member
ports of the aggregate interface becomes DOWN.
•
DOWN (Loopback detection down)—The port is shut down
because the loopback detection module has detected loops.
•
DOWN ( Monitor-Link uplink down )—The port is shut down
because the monitor link module has detected that the uplink is
down.
•
MAD ShutDown—After an IRF split, the state of all interfaces
except the excluded ports in the IRF in recovery state is set to
DOWN.
•
Not connected—No physical connection exists (possibly
because the network cable is disconnected or faulty).
•
Storm-Constrain—The port is shut down because the unknown
unicast traffic, multicast traffic, or broadcast traffic exceeds the
upper limit.
•
STP DOWN—The port is shut down by the STP BPDU guard
function.
•
Port Security Disabled—The port is shut down by the intrusion
detection mechanism because the port receives illegal packets.
•
Standby—The interface is in the Standby state.
