enable the port from the disabled state. For details on configuring the error disable timeout interval,
refer to
Specifying the error disable timeout interval on page 423.
To enable the error disable timeout timer, perform the following steps from privileged EXEC mode. By
default, the timeout feature is disabled.
1. Enter the configure terminal command to change to global configuration mode.
switch# configure terminal
2. Enter the protocol command to enable STP, RSTP, MSTP, PVST+, or R-PVST+.
switch(config)# protocol spanning-tree stp
3. Enable the error disable timeout timer.
switch(conf-stp)# error-disable-timeout enable
Specifying the error disable timeout interval
In STP, RSTP, MSTP, PVST+, or R-PVST+ mode, use the error-disable-timeout command to specify
the time in seconds it takes for an interface to time out. The range is from 10 through 1000000 seconds.
The default is 300 seconds. By default, the timeout feature is disabled.
To specify the time in seconds it takes for an interface to time out, perform the following steps from
privileged EXEC mode.
1. Enter the configure terminal command to change to global configuration mode.
switch# configure terminal
2. Enter the protocol command to enable STP, RSTP, MSTP, PVST+, or R-PVST+.
switch(config)# protocol spanning-tree stp
3. Specify the time in seconds it takes for an interface to time out.
switch(conf-stp)# error-disable-timeout interval 60
Specifying the port-channel path cost
In STP, RSTP, MSTP, PVST+, or R-PVST+ mode, use the port-channel path-cost command to
specify the port-channel path cost. The default port cost is standard. The path cost options are as
follows:
• custom — Specifies that the path cost changes according to the port-channel’s bandwidth.
• standard — Specifies that the path cost does not change according to the port-channel’s bandwidth.
To specify the port-channel path cost, perform the following steps from privileged EXEC mode.
1. Enter the configure terminal command to change to global configuration mode.
switch# configure terminal
2. Enter the protocol command to enable STP, RSTP, MSTP, PVST+, or R-PVST+.
switch(config)# protocol spanning-tree stp
3. Specify the port-channel path cost.
switch(conf-stp)# port-channel path-cost custom
4. Return to privileged EXEC mode.
switch(config)# end
5. Enter the copy command to save the running-config file to the startup-config file.
switch# copy running-config startup-config
Specifying the transmit hold count (RSTP, MSTP, and R-PVST+)
In RSTP, MSTP, or R-PVST+ mode, use the transmit-holdcount command to configure the BPDU
burst size by specifying the transmit hold count value. The command configures the maximum number
of BPDUs transmitted per second for RSTP and MSTP before pausing for 1 second. The range is 1
through 10. The default is 6.
