The root bridge identifier parameter displays the bridge priority value and
MAC address of the root switch of the spanning tree domain. The values
are separated by a slash (/). This parameter only appears when RSTP is
activated on the stack.
The root path cost parameter displays the path cost from the stack to the
root bridge of the spanning tree domain. If the stack is the root bridge, the
path cost is 0. This parameter only appears when RSTP is activated on the
stack.
The PORTCONFIG parameter displays the current RSTP parameter
settings for the ports. An example is shown in Figure 31.
