Figure 2-20 After Applying the STA Rules
The switch with the lowest Bridge ID (switch C) was elected the root bridge, and the
ports were selected to give a high port cost between switches B and C. The two
(optional) Gigabit ports (default port cost = 4) on switch A are connected to one
(optional) Gigabit port on both switch B and C. The redundant link 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.
2.3.2 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
Configure the following parameters and click the Apply button to implement them:
Status: Default<Disabled>.This field can be toggled between Enabled and Disabled
using the pulld own menu. This will enable or disable the Spanning Tree Protocol
(STP), globally, for the Switch.
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
