Click Apply to update the switch configuration. Your changes take effect immediately but are not
retained across a switch reset unless you click Save Configuration.
Designated Bridge The bridge ID of the bridge with the designated port.
Designated Port The port ID of the designated port.
Topology Change
Acknowledge
Indicates whether the next BPDU to be transmitted for this port will have the topology change
acknowledgment flag set.
Auto Edge When enabled, Auto Edge allows the interface to become an edge port if it does not receive
any BPDUs within a given amount of time.
Edge Port Indicates whether the interface is configured as an edge port (Enabled).
Point-to-point MAC Indicates whether the link type for the interface is a point-to-point link.
Root Guard When enabled, Root Guard allows the interface to discard any superior information it receives
to protect the root of the device from changing. The port gets put into discarding state and
does not forward any frames.
Loop Guard When enabled, Loop Guard prevents an interface from erroneously transitioning from
blocking state to forwarding when the interface stops receiving BPDUs. The port is marked
as being in loop-inconsistent state. In this state, the interface does not forward frames.
TCN Guard When enabled, TCN Guard restricts the interface from propagating any topology change
information received through that interface.
CST Regional Root The bridge ID of the bridge that has been elected as the root bridge of the CST region.
CST Path Cost The path cost from the interface to the CST regional root.
Loop Inconsistent State Identifies whether the interface is currently in a loop inconsistent state. An interface
transitions to a loop inconsistent state if loop guard is enabled and the port stops receiving
BPDUs. In this state, the interface does not transmit frames.
Transitions Into Loop
Inconsistent State
The number of times this interface has transitioned into loop inconsistent state.
Transitions Out Of Loop
Inconsistent State
The number of times this interface has transitioned out of loop inconsistent state.
