![]() DISABLED -The port is not participating in STP.When a port is in the BLOCKING state, the port does not transmit or receive user frames, but the port does continue to receive STP BPDUs. The device or VLAN can reach the root bridge using another port, whose state is FORWARDING. BLOCKING -STP has blocked Layer 2 traffic on this port to prevent a loop.This field displays only when port VLAN is enabled.ĭisplays the port number - stack-unit/slotnum/portnum.ĭisplays the STP priority of the port in hexadecimal format.ĭisplays the STP state of the port. ![]() The value is shown in hexadecimal format.ĭisplays the number of seconds this device or VLAN waits for a Hello message from the root bridge before deciding that the root has become unavailable and performing a reconvergence.ĭisplays the interval between each configuration Bridge Packet Data Unit (BPDU) sent by the root bridge.ĭisplays the minimum number of seconds that must elapse between transmissions of consecutive configuration BPDUs on a port.ĭisplays the number of seconds this device or VLAN waits following a topology change and consequent reconvergence.ĭisplays the number of seconds since the last time a topology change occurred.ĭisplays the number of times the topology has changed since the device was reloaded.ĭisplays the STP address of this device or VLAN.ĭisplays the VLAN that the port is in. If this device is the root bridge, then the value isĭisplays the STP priority of this device or VLAN. If this device is the root bridge, then the root cost is 0.ĭisplays the port on this device that connects to the root bridge. If you have not configured port-based VLANs on this device, all STP information is for VLAN 1.ĭisplays the ID assigned by STP to the root bridge for this spanning tree.ĭisplays the cumulative cost from this bridge to the root bridge. STP Bridge parameters (global parameters)ĭisplays the port-based virtual local area network (VLAN) that contains this spanning tree (instance of STP).
