Figure 65. SHOW STP Command

The bridge priority, bridge hello time, and bridge max age parameters
display two values when STP is enabled on the switch (for example,
Bridge Forwarding Delay .. 15/15). The first number is the configured
value on the switch for the parameter and the second is the value the
switch obtained from the root bridge and is actually using for the
parameter. The switch displays only the configured values when spanning
tree is not activated on the switch.

The Status parameter displays whether STP is enabled or disabled on the
switch.

For definitions of the bridge priority, hello time, forwarding delay, and max
age parameters, refer to “SET STP” on page 522.

The bridge Identifier parameter consists of the switch’s bridge priority
value and MAC address, separated by a slash (/). To change the switch’s
priority value, refer to “SET STP” on page 522. The MAC address of the
switch cannot be changed.the MAC address of the switch.
