Table 12: Spanning-Tree Protocol Configuration Parameters

Field Function
General
Protocol Name Specifies the spanning-tree protocol type: STP, MSTP,
or RSTP.
Disable Disables spanning-tree protocols on the interface.
BPDU Protect Specifies BPDU protection on all edge interfaces on
the switch.
Bridge Priority 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.
Forward Delay Specifies the number of seconds an interface waits
before changing from spanning-tree learning and
listening states to the forwarding state.
Hello Time Specifies the time interval in seconds at which the
root bridge transmits configuration BPDUs.
Max Age 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 Hops (MSTP only) Specifies the number of hops in a region
before the BPDU is discarded.
Configuration Name (MSTP only) Specifies the MSTP region name carried
in the MSTP BPDUs.
Revision Level (MSTP only) Specifies the revision number of the
MSTP configuration.
Force STP Version Enables or disables STP.
NOTE: This option
is supported only on
EX4300 switches.
