tab (should be the displayed tab by default).
Use the drop-down menu to define MSTP status. The default is Enabled.
Displays the maximum allowed hops for a BPDU (Bridge Protocol Data Unit) in an
MSTP region. This value is used by all the MSTP instances.
Displays the different versions of STP supported.
Displays the current protocol version in use. Available MSTP protocol versions are:
• forceNonStp
• forceLegacyDot1d
• forceDot1w
• autoDot1s
• unknown
Enter a name for the MST region. This is used when configuring multiple regions
within the network. Each switch running MSTP is configured with a unique MST
region name. This helps when keeping track of MSTP configuration changes.
Increment this number with each configuration change. The revision-level specifies
the revision-level of the current configuration.
Assign a MST revision level number to the MSTP region to which the device
belongs. Each switch running is configured with a unique MSTP name and revision
number. This helps when keeping track of MSTP configuration changes. Increment
this number with each configuration change. The revision level specifies the
revision level of the current configuration.
timeout is used to set a timeout value for ports disabled resulting from a BPDU
guard.
The BPDU guard feature shuts down the port on receiving a BPDU on a BPDU-guard
enabled port.
Displays the ID format currently in use.
Select this checkbox to enable BPDU filter for all portfast enabled ports.The
Spanning Tree Protocol sends BPDUs from all the ports. Enabling the BPDU filter
feature ensures PortFast enabled ports do not transmit or receive any BPDUs.
Select this checkbox to enable BPDU guard for all portfast enabled ports.
When the BPDU Guard feature is set for bridge, all portfast-enabled ports of the
bridge that have BPDU set to default shutdown the port on receiving a BPDU. Hence
no BPDUs are processed.
Select this checkbox to enable interoperability with Cisco's version of MSTP, which
is incompatible with standard MSTP.
