OmniSwitch 6250 CLI Reference Guide
The Spanning Tree bridge priority for the instance. The lower the num-
ber, the higher the priority. Configured through the
command.
The bridge identifier for this Spanning Tree instance. Consists of the
bridge priority value (in hex) concatenated with the dedicated bridge
MAC address.
The bridge identifier for the root of the Spanning Tree for this instance.
The cost of the path to the root for this Spanning Tree instance.
The port that offers the lowest cost path from this bridge to the root
bridge for this Spanning Tree instance.
The cost of the next best root port for this Spanning Tree instance.
The port that offers the next best (second lowest) cost path to the root
bridge for this Spanning Tree instance.
The count to limit the transmission of BPDU through the port.
The number of topology changes detected by this Spanning Tree
instance since the management entity was last reset or initialized.
The amount of time (in hundredths of seconds) since the last topology
change was detected by this Spanning Tree instance (hh:mm:ss or dd
days and hh:mm:ss).
The amount of time (in seconds) that Spanning Tree Protocol informa-
tion is retained before it is discarded. Configured through the
max age command.
The amount of time (in seconds) that a port will remain in the Listening
state and then the Learning state until it reaches the forwarding state.
This is also the amount of time used to age out all dynamic entries in
the Forwarding Database when a topology change occurs. Configured
through the bridge forward delay
The amount of time (in seconds) between the transmission of Configu-
ration BPDUs on any port that is the Spanning Tree root or is attempt-
ing to become the Spanning Tree root. Configured through the
hello time command.
The Max Age value for the root bridge.
The Forward Delay value for the root bridge.
The Hello Time value for the root bridge.
