342 Asanté IntraCore 36000 Series
Usage Guidelines
You can enable this option if an interface is attached to a LAN segment that is at the end of a bridged LAN
or to an end node. Since end nodes cannot cause forwarding loops, they can pass directly through to the
spanning tree forwarding state. Specifying Edge Ports provides quicker convergence for devices such as
workstations or servers, retains the current forwarding database to reduce the amount of frame flooding
required to rebuild address tables during reconfiguration events, does not cause the spanning tree to initiate
reconfiguration when the interface changes state, and also overcomes other STA-related timeout problems.
The Edge Port should only be enabled for ports connected to an end-node device.
This command has the same effect as the spanning-tree portfast.
Example
The following is sample output from the spanning-tree edge-port command.
Console(config)#interface ethernet ethernet 1/5
Console(config-if)#spanning-tree edge-port
Console(config-if)#

16.214 spanning-tree forward-time
This command configures the spanning tree bridge forward time globally for this switch. Use the no form to
restore the default.
Syntax Description
spanning-tree forward-time seconds
no spanning-tree forward-time
seconds Time in seconds. (Range: 4 -30 seconds) The minimum value is the higher of 4
or [(max-age / 2) + 1].
Default
15 seconds
Command Mode
Global Configuration
Usage Guidelines
This command sets the maximum time (in seconds) the root device will wait before changing states (For
example, 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 the discarding state; otherwise, temporary data
loops might result.
