Field Description
ifIndex The interface or LAG.
Port Type For normal ports this field displays Normal. Otherwise, the options are as
follows:
• Mirrored. The port is a participating in port mirroring as a mirrored port.
• Probe. The port is a participating in port mirroring as the probe port.
• Port Channel. The port is a member of a LAG.
Port Channel ID If the port is a member of a port channel (LAG), the port channel’s interface ID
and name are shown. Otherwise, Disable is shown.
Port Role Each MST bridge port that is enabled is assigned a port role for each spanning
tree. The port role is one of the following values: Root, Designated, Alternate,
Backup, Master, or Disabled.
STP Mode The Spanning Tree Protocol administrative mode that is associated with the port
or port channel. The options are as follows:
• Enable. Spanning tree is enabled for the port.
• Disable. Spanning tree is disabled for the port.
STP State The port's current Spanning Tree state. This state controls what action a port
takes on receipt of a frame. If the bridge detects a malfunctioning port, it places
that port into the broken state. The states are defined in IEEE 802.1D:
• Disabled
• Blocking
• Listening
• Learning
• Forwarding
• Broken
Admin Mode The port control administration state. The port must be enabled for it to be
allowed into the network. The default is Enabled.
Flow Control Mode Indicates whether flow control is enabled or disabled for the port. This field does
not apply to LAGs.
LACP Mode Indicates the Link Aggregation Control Protocol administrative state. The mode
must be enabled for the port to participate in link aggregation.
Physical Mode Indicates the port speed and duplex mode. In autonegotiation mode the duplex
mode and speed are set from the autonegotiation process.
Physical Status Indicates the port speed and duplex mode for physical interfaces.
