6. Define the following PortFast parameters for the profile configuration:
7. Define the following Error Disable settings:
8. Use the Spanning Tree Instance table to add indexes to the spanning tree topology.
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.
9. Use the Spanning Tree Instance VLANs table to add VLAN instance indexes (by numeric ID) and VLANs to the spanning
tree topology.
10. Select the OK button located at the bottom right of the screen to save the changes. Select Reset to revert to the last saved
configuration.
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
start/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 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.
PortFast BPDU Filter Select Enable to invoke a BPDU filter for this PortFast enabled port. Enabling the BPDU
filter 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 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.
