7.3 Configuring Interface Settings for STP

Use the Spanning Tree > STP (Configure Interface - Configure) page to configure RSTP
attributes for specific interfaces, including port priority, path cost, link type, and edge port.
You may use a different priority or path cost for ports of the same media type to indicate the
preferred path, link type to indicate a point-to-point connection or sharedmedia connection,
and edge port to indicate if the attached device can support fast forwarding. (References to
"ports" in this section means "interfaces," which includes both ports and trunks.)
To configure interface settings for STP:
1. Click Spanning Tree, STP.
2. Select Configure Interface from the Step list.
3. Select Configure from the Action list.
4. Modify any of the required attributes.
5. Click Apply.

Description
The maximum time (in seconds) this device will wait before changing
states (i.e., discarding to learning to forwarding). This delay is required
because every device must receive information about topology changes
before it starts to forward frames. In addition, each port needs time to
listen for conflicting information that would make it return to a
discarding state; otherwise, temporary data loops might result.
Minimum: The higher of 4 or [(Max. Age / 2) + 1]
Maximum: 30
