The port-based VLAN that owns the STP instance. VLAN 1 is the default
VLAN. If you have not configured port-based VLANs on this device, all
802.1W information is for VLAN 1.
The ID assigned by STP to the root bridge for this spanning tree.
The cumulative cost from this bridge to the root bridge. If this device is the root
bridge, then the root cost is 0.
The bridge from where the root information was received.It can be from the root
bridge itself, but it could also be from another bridge.
The port on this device that connects to the root bridge. If this device is the root
bridge, then the value is "Root" instead of a port number.
The number of seconds this device or VLAN waits for a hello message from the root
bridge before deciding the root has become unavailable and performing a
reconvergence.
The number of seconds a non-edge Designated port waits until it can apply any of
the following transitions, if the RST BPDU it receives does not have an agreed flag:
•
Discarding state to learning state
•
Learning state to forwarding state
When a non-edge port receives the RST BPDU it goes into forwarding state within 4
seconds or after two hello timers expire on the port.
Fwd Dly is also the number of seconds that a Root port waits for an RST BPDU with
a proposal flag before it applies the state transitions listed above.
If the port is operating in 802.1D compatible mode, then forward delay functionality
is the same as in 802.1D (STP).
The interval between each configuration BPDU sent by the root bridge.
The ID of the bridge
The configured max age for this bridge. The default is 20.
The configured hello time for this bridge.The default is 2.
The configured forward delay time for this bridge. The default is 15.
The configured force version value. One of the following value is displayed:
•
0 – The bridge has been forced to operate in an STP compatibility mode.
•
2 – The bridge has been forced to operate in an 802.1W mode. (This is the
default.)
The number of BPDUs that can be transmitted per Hello Interval. The
default is 3.
The port-based VLAN that owns the STP instance. VLAN 1 is the default
VLAN. If you have not configured port-based VLANs on this device, all
802.1W information is for VLAN 1.
The port number.
The configured priority of the port. The default is 128 or 0x80.
The port's STP path cost.
Indicates if the point-to-point-mac parameter is configured to be a point-to-point
link:
•
T – The link is configured as a point-to-point link.
•
F – The link is not configured as a point-to-point link. This is the default.
