Setting the RSTP Timeout Interval

Setting the RSTP Timeout Interval


If a device does not receive any BPDUs from the upstream device within the timeout interval, the device considers the upstream device to be down and triggers spanning tree recalculation.

Sometimes, a device cannot receive the BPDU from the upstream device within the timeout interval because the upstream device is busy. In this case, recalculating the spanning tree will waste network resources. Set a long timeout interval on a stable network to avoid this.

The timeout interval is calculated as follows:

Timeout interval = Hello Time x 3 x Timer Factor


  1. Run:


    The system view is displayed.

  2. Run:

    stp timer-factor factor

    The Timer Factor value is set. This parameter determines the timeout interval during which the device waits for BPDUs from the upstream device.

    By default, the timeout period is 9 times the Hello Time value.
