Configuring System STP Parameters
250 Avidia System Configuration and Management User Manual
[-hellotime ]
The interval, in seconds, at which you want the system to send Spanning Tree Protocol
packets. The valid range is 1 to 10. The default value is 2.
[-fddelay ]
The number of seconds you want the system to wait before changing the state of a particular
interface (changing to blocked, for example). The valid range is 4 to 30. The default value
is 15.
This delay prevents the interface states from changing so rapidly that the STP cannot keep
up with the current topology of the network and cannot therefore manage bridging
efficiently.
Example
::globalstp=> modify -stpenable on -maxage 20 -hellotime 2
-fddelay 15
