Set the following MSTP Configuration parameters:
MSTP Enable Select this option to enable MSTP for this profile. MSTP is disabled by default, so if requiring
different (groups) of VLANs with the profile supported network segment.
Max Hop Count Define the maximum number of hops the BPDU will consider valid in the spanning tree topology.
The available range is from 7 -127. The default setting is 20.
MST Config Name Define a 64 character maximum name for the MST region as an identifier.
MST Revision Level Set a numeric revision value ID for MST configuration information. Set a value from 0 - 255. The
default setting is 0.
Cisco MSTP Interoperability Select either the Enable or Disable radio buttons to enable/disable interoperability with Cisco’s
version of MSTP, which is incompatible with standard MSTP. This setting is disabled by default.
Hello Time Set a BPDU hello interval from 1 - 10 seconds. BPDUs are exchanged regularly (every 2 seconds
by default) and enable supported devices to keep track of network changes and star/stop port
forwarding as required.
Forward Delay Set the forward delay time from 4 - 30 seconds. When a device is first attached to a port, it does
not immediately start to forward data. It first processes BPDUs and determines the network
topology. When a host is attached the port always goes into the forwarding state, after a delay of
while it goes through the listening and learning states. The time spent in the listening and
learning states is defined by the forward delay (15 seconds by default).
Maximum Age Use the spinner control to set the maximum time (in seconds) to listen for the root bridge. The
root bridge is the spanning tree bridge with the smallest (lowest) bridge ID. Each bridge has a
unique ID and a configurable priority number, the bridge ID contains both. The available range is
from 6 - 40. The default setting is 20.
