FIGURE 40 Profile - Network Spanning Tree screen
4. 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).
