5.5.3 STP Interface

Click the Service Management > STP > STP Interface page to configure attributes for specific
interfaces, including port priority, path cost, protection 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.
Different link type indicates a point-to-point connection or shared-media connection, and
different edge port indicates that the attached device can support fast forwarding.

Description
Max-age ensures that the old information will not be
endlessly circled within the network's redundant path, and
thus stop the valid transmission of the new information.
The value is set by the root bridge to confirm that the
spanning tree configuration value of the switch accords
with the other devices on the bridge LAN. If the value is
timeout, while the switch has not received the BPDU
packet from root bridge, the switch starts to send its BPDU
to all the other switches to ask for becoming the root
bridge. If the switch has the minimal bridge identifier, it
will become root bridge. User can set the value from 6-40
seconds, the default is 20 seconds.
