Specifying The Bridge Maximum Aging Time; Enabling The Error Disable Timeout Timer; Specifying The Error Disable Timeout Interval - Dell 53-1002116-01 Administrator's Manual

Specifying the bridge maximum aging time

In any mode (STP, RSTP, or MSTP), use this command to control the maximum length of time that
passes before an interface saves its Bridge Protocol Data Unit (BPDU) configuration information.
When configuring the maximum aging time, the max-age setting must be greater than the
hello-time setting. The range is 6 through 40 seconds. The default is 20 seconds. The following
relationship should be kept:
2*(forward_delay - 1)>=max_age>=2*(hello_time + 1)
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.
3. Specify the bridge maximum aging time.

Enabling the error disable timeout timer

In any mode (STP, RSTP, or MSTP), use this command to enable the timer to bring a port out of the
disabled state. 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
timeout interval"
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 access global configuration mode.
2. Enter the protocol command to enable STP, RSTP, or MSTP.
3. Enable the error disable timeout timer.

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.
3. Specify the time in seconds it takes for an interface to time out.
