SHOW RSTP
Syntax
show rstp [portconfig= port ] [portstate= port ]
Parameters
portconfig Displays the RSTP port settings. You can specify more
than one port at a time. For instructions, refer to “Port
Numbers in Commands” on page 48.
portstate Displays the RSTP status of the ports. You can specify
more than one port at a time.
Description
You use this command to display the RSTP parameter settings. Entering
the command without either of the parameters displays the information
shown in Figure 73.
Figure 73. Example of the SHOW RSTP Command
The bridge priority, bridge hello time, and bridge max age parameters will
have two values if RSTP is enabled on the switch (for example, Bridge
Forwarding .. 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 currently using for the parameter. The switch
displays only the configured values for these parameters if spanning tree
is not enabled on the switch.
The Status parameter indicates whether STP is enabled or disabled.
For definitions of the force version, bridge priority, hello time, forward
delay, and max age parameters, refer to “SET RSTP” on page 596.
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 RSTP” on page 596. The MAC address of the
switch cannot be changed.
