Table 53: Spanning-Tree Protocol Configuration Parameters
Your ActionFunctionField
General
None.Specifies the spanning-tree protocol type: STP, MSTP,
or RSTP.
Protocol Name
To enable this option, select the check box.Disables spanning-tree protocols on the interface.Disable
To enable this option, select the check box.Specifies BPDU protection on all edge interfaces on
the switch.
BPDU Protect
Select a value from the list.Specifies the bridge priority. The bridge priority
determines which bridge is elected as the root bridge.
If two bridges have the same path cost to the root
bridge, the bridge priority determines which bridge
becomes the designated bridge for a LAN segment.
Bridge Priority
Type a value.Specifies the number of seconds an interface waits
before changing from spanning-tree learning and
listening states to the forwarding state.
Forward Delay
Type a value.Specifies the time interval in seconds at which the
root bridge transmits configuration BPDUs.
Hello Time
Type a value.Specifies the maximum-aging time in seconds for all
MST instances. The maximum aging time is the
number of seconds a switch waits without receiving
spanning-tree configuration messages before
attempting a reconfiguration.
Max Age
Type a value.(MSTP only) Specifies the number of hops in a region
before the BPDU is discarded.
Max Hops
Type a name.(MSTP only) Specifies the MSTP region name carried
in the MSTP BPDUs.
Configuration Name
Type a value.(MSTP only) Specifies the revision number of the
MSTP configuration.
