Description
This field indicates the ifIndex of the interface table entry associated with this
port on an adapter.
For most ports this field is blank. Otherwise the possible values are:
• Mirrored: Indicates that the port has been configured as a monitoring port
and is the source port in a port mirroring session. For additional information
about port monitoring and probe ports, see
page 6-24.
• Probe: Indicates that the port has been configured as a monitoring port and
is the destination port in a port mirroring session. For additional information
about port monitoring and probe ports, see
page 6-24.
• Port Channel: Indicates that the port has been configured as a member of a
port-channel, which is also known as a link Aggregation Group (LAG).
If the port is a member of a port channel, the port channel's interface ID and
name are shown. Otherwise, Disable is shown.
Each MST Bridge Port that is enabled is assigned a Port Role for each
spanning tree. The port role will be one of the following values: Root Port,
Designated Port, Alternate Port, Backup Port, Master Port, or Disabled Port.
Displays the Spanning Tree Protocol (STP) Administrative Mode for the port or
LAG. The possible values for this field are:
• Enable: Enables the Spanning Tree Protocol for this port.
• Disable: Disables the Spanning Tree Protocol for this port.
Displays the port's current state Spanning Tree state. This state controls what
action a port takes on receipt of a frame. If the bridge detects a malfunctioning
port it will place that port into the broken state. The other five states are
defined in IEEE 802.1D:
• Disabled
• Blocking
• Listening
• Learning
• Forwarding
• Broken
Displays the port control administration state:
• Enable: The port can participate in the network (default).
• Disable: The port is administratively down and does not participate in the
network.
Selects the Link Aggregation Control Protocol administration state:
• Enable: Specifies that the port is allowed to participate in a port channel
(LAG), which is the default mode.
• Disable: Specifies that the port cannot participate in a port channel (LAG).
