Brocade Communications Systems 53-1002163-02 manual Enabling the error disable timeout timer

STP, RSTP, and MSTP configuration and management 7

To specify the bridge maximum aging time, perform the following steps from privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Enter the protocol command to enable STP, RSTP, or MSTP.

switch(config)#protocol spanning-tree stp

3. Specify the bridge maximum aging time.

switch(conf-stp)##max-age 25

Enabling the error disable timeout timer

In any mode (STP, RSTP, or MSTP), use this command to specify the time in seconds required for the timer to expire. When the STP BPDU guard disables a port, the port remains in the disabled state unless the port is enabled manually. This command allows you to enable the port from the disabled state. For details on configuring the error disable timeout interval, see “Specifying the error disable timeout interval” on page 67. By default, the timeout feature is disabled.

To enable the error disable timeout timer, perform the following steps from privileged EXEC mode.

1.Enter the configure terminal command to access global configuration mode.

2.Enter the protocol command to enable STP, RSTP, or MSTP.

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 any mode (STP, RSTP, or MSTP), use this command to specify the time in seconds it takes for an interface to time out. The range is 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 access global configuration mode.

2.Enter the protocol command to enable STP, RSTP, or MSTP.

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 any mode (STP, RSTP, or MSTP), use this command to specify the port-channel path cost. The default port cost is standard. The path cost options are:

•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.
