Configuring Spanning Tree
STP/RSTP Configurations
Follow these steps to configure STP/RSTP globally:
1) In the
Parameters Config
section, configure the global parameters of STP/RSTP and
click
Apply
.
CIST Priority
Specify the CIST priority of the switch. The valid values are from 0 to 61440,
which are divisible by 4096.By default, it is 32768. The switch with the lower
value has the higher priority.
CIST priority is usually a parameter configured in MSTP, which means the
priority of a switch in CIST. The switch with the highest priority will be elected
as the root bridge in CIST.
In STP/RSTP, CIST priority means the priority of a switch in the spanning tree.
The switch with the highest priority is elected as the root bridge.
Hello Time
Specify the interval to send BPDUs. The valid values are from 1 to 10 in
seconds, and the default value is 2.
Max Age
Specify the maximum time the switch can wait without receiving a BPDU
before attempting to regenerate a spanning tree. The valid values are from 6
to 40 in seconds, and the default value is 20.
Forward Delay
Specify the time for the port to transit its state after the network topology is
changed. The valid values are from 4 to 30 in seconds, and the default value
is 15.
TxHoldCount
Specify the maximum BPDU transmission rate of a port. The valid values are
from 1 to 20, and the default value is 5.
Max Hops
Specify the scale of an MST region.
Note: Max Hops is a parameter configured in MSTP. You need not configure
it if the spanning tree mode is STP/RSTP.
Note:
To prevent frequent network flapping, make sure that Hello Time, Forward Delay, and Max Age
conform to the following formulas:
•
2*(Hello Time + 1) <= Max Age
•
2*(Forward Delay - 1) >= Max Age
2) In the
Global Config
section, enable spanning tree function, choose the STP mode as
STP/RSTP, and click
Apply
.
Spanning-Tree
Enable or disable spanning tree function globally on the switch.
