between switch B and C is deliberately chosen as a 100 Mbps Fast Ethernet link (default port cost = 19).
Gigabit ports could be used, but the port cost should be increased from the default to ensure that the link
between switch B and switch C is the blocked link.
4.6.2 Spanning Tree Configuration
The Spanning Tree Protocol (STP) operates on two levels: On the switch level, the settings are globally
implemented. On the port level, the settings are implemented on a. per user-defined Group of ports.
1. Spanning Tree Configuration
The “
Rapid Spanning Tree Bridge Configure”
table allows configuring the spanning tree parameters.
Rapid Spanning Tree Status:
The spanning tree function of the switch is default disabled.
This field
enables to turn on the spanning tree on the switch.
Force Protocol Version:
0 for IEEE 802.1D Spanning Tree, 2 for IEEE 802.1W Rapid Spanning Tree
Max Age:
(6 - 40 sec) the default setting is 20
Hello Time:
(1 - 10sec) the default setting is 2
Forward Delay:
(4 -30 sec) the default setting is 15
Bridge Priority:
(0 - 61440) the default setting is 32768
2. Bridge Information
The informations of the STP Root show in the Bridge Information table.
3. STP Port Configuration
The following fields can be set for STP port configuration:
Port Priority:
Defines if this port is more or less likely to become the root port. The range is from 0 to 255,
