7. Set the following PortFast parameters for the profile configuration:
8. Set the following Error Disable parameters for the profile configuration:
9. Use the Spanning Tree Instance table to add indexes to the spanning tree topology.
10. Add up to 16 indexes and use the Priority setting to define the bridge priority used to determine
the root bridge. The lower the setting defined, the greater the likelihood of becoming the root
bridge in the spanning tree topology.
11. Use the Spanning Tree Instance VLANs table to add up to 15 VLAN instance indexes (by
numeric ID) and VLANs to the spanning tree topology as virtual route resources.
12. Select the OK button located at the bottom right of the screen to save the changes and
overrides. Select Reset to revert to the last saved configuration.
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 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 listening and learning states is set 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 seconds. The default setting is 20
seconds.
PortFast BPDU Filter Select Enable to invoke a BPDU filter for this portfast enabled port. Enabling the BPDU
filter feature ensures this port channel does not transmit or receive any BPDUs.
BPDUs are exchanged regularly and enable the access point to keep track of network
changes and to start and stop port forwarding as required. The default setting is
Disabled.
PortFast BPDU Guard Select Enable to invoke a BPDU guard for the portfast enabled port. Enabling the
BPDU Guard feature means this port will shutdown on receiving a BPDU. Thus, no
BPDUs are processed. BPDUs are exchanged regularly and enable the access point to
keep track of network changes and to start and stop port forwarding as required. The
default setting is Disabled.
Enable Recovery Select this option to enable a error disable timeout resulting from a BPDU guard. This
setting is disabled by default.
Recovery Interval Define the recovery interval used to enable disabled ports. The available range is
from 10 - 1,000,000 seconds with a default setting of 300.
