Description
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
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.
The Port Media Type.
The ARP Type of the port.
Shows the port control administration state, which can be one of the following:
• Enabled: The port can participate in the network (default).
• Disabled: The port is administratively down and does not participate in the network.
Shows whether the Broadcast Storm Recovery Mode, which can be one of the
following:
• Enabled: When the broadcast traffic on the specified Ethernet port exceeds the
configured threshold, the switch blocks (discards) the broadcast traffic.
• Disabled: The port does not block broadcast traffic if traffic on the port exceeds the
configured threshold. The factory default is disabled.
Shows the Broadcast Storm Recovery Level, which is the data rate at which storm
control activates. The value is a percentage of port speed and ranges from 0-100. The
factory default is 5 percent of port speed.
Shows the Multicast Storm Recovery Mode, which is one of the following:
• Enabled: When the multicast traffic on the specified Ethernet port exceeds the
configured threshold, the switch blocks (discards) the multicast traffic.
• Disabled: The port does not block multicast traffic if traffic on the port exceeds the
configured threshold. The factory default is disabled.
Shows the Multicast Storm Recovery Level, which is the data rate at which storm
control activates. The value is a percentage of port speed and ranges from 0-100. The
factory default is 5 percent of port speed.
Shows the Unicast Storm Recovery Mode, which can be one of the following:
• Enabled: When the unicast traffic on the specified Ethernet port exceeds the
configured threshold, the switch blocks (discards) the unicast traffic.
• Disabled: The port does not block unicast traffic if the unicast traffic on the port
exceeds the configured threshold. The factory default is disabled.
Shows the Unicast Storm Recovery Level, which is the data rate at which storm
control activates. The value is a percentage of port speed and ranges from 0-100.The
factory default is 5 percent of port speed.
