•
Bridge hello time
•
Bridge maximum age
•
Forwarding delay
•
Current bridge configuration
The following table describes the Bridge Spanning Tree Configuration Menu options.

Bridge Spanning Tree Configuration Menu options
Command
prior <0-65535>
hello <1-10>
mxage <6-40>
Description
Displays current Spanning Tree Protocol parameters.
prior
- Set bridge Priority [0-65535]
hello
- Set bridge Hello Time [1-10 secs]
mxage
- Set bridge Max Age (6-40 secs)
fwd
- Set bridge Forward Delay (4-30 secs)
cur
- Display current bridge parameters
Description
Configures the bridge priority. The bridge priority parameter controls which bridge
on the network is the STP root bridge.
To make this switch the root bridge, configure the bridge priority lower than all other
switches and bridges on your network. The lower the value, the higher the bridge
priority. The range is 0 to 65535, and the default is 32768.
RSTP/MSTP: The range is 0 to 61440, in steps of 4096 (0, 4096, 8192...), and the
default is 32768.
This command does not apply to MSTP. See the "Common Internal Spanning Tree
configuration" section for more information.
Configures the bridge hello time. The hello time specifies how often the root bridge
transmits a configuration bridge protocol data unit (BPDU).
Any bridge that is not the root bridge uses the root bridge hello value. The range is 1
to 10 seconds, and the default is 2 seconds.
This command does not apply to MSTP. See the "Common Internal Spanning Tree
configuration" section for more information.
Configures the bridge maximum age. The maximum age parameter specifies the
maximum time the bridge waits without receiving a configuration bridge protocol
data unit before it reconfigures the STP network. The range is 6 to 40 seconds, and
the default is 20 seconds.
This command does not apply to MSTP. See the "Common Internal Spanning Tree
configuration" section for more information.
