Description
This command displays the current values for the STP parameters. An
example of the display is shown in Figure 35.
Figure 35. SHOW STP Command
The bridge priority, bridge hello time, and bridge max age parameters
display two values when STP is enabled on the stack (for example, Bridge
Forwarding Delay .. 15/15). The first number is the configured value on the
stack for the parameter and the second is the value the stack obtained
from the root bridge and is actually using for the parameter. The stack
displays only the configured values when spanning tree is not activated on
the stack.
The Status parameter displays whether STP is enabled or disabled on the
stack.
For definitions of the bridge priority, hello time, forwarding delay, and max
age parameters, refer to “SET STP” on page 348.
The bridge Identifier parameter consists of the stack’s bridge priority value
and MAC address, separated by a slash (/). To change the stack’s priority
value, refer to “SET STP” on page 348. The MAC address of the stack
cannot be changed.
