Field Description
F(a)—Autonegotiated full duplex.
• H—Half duplex.
• H(a)—Autonegotiated half duplex.
Type
Link type of the interface:
• A—Access.
• H—Hybrid.
• T—Trunk.
PVID Port VLAN ID.
Cause
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.
