set class-of-service pfc-watchdog code-point detect-interval

The set class-of-service pfc-watchdog code-point detect-interval command configures the time interval of PFC deadlock detection. The value of detection time depends on the configured granularity and detect-timer, the value of detection time = granularity x detect-interval.

The delete class-of-service pfc-watchdog code-point detect-interval command restores the default configuration.

Command Syntax

For Trident3 platforms:

set class-of-service pfc-watchdog code-point <cos> detect-interval <detect-interval>

delete class-of-service pfc-watchdog code-point <cos> detect-interval

For Tomahawk3 platforms:

set class-of-service interface <interface-name> pfc-watchdog code-point <cos> detect-interval <detect-interval>

delete class-of-service interface <interface-name> pfc-watchdog code-point <cos> detect-interval

Parameter

Usage Guidelines

After receiving the PFC Pause frame, the internal scheduler will stop forwarding the queue traffic of corresponding priority and start the timer to detect the PFC Pause frame received by the queue based on the set deadlock detection and granularity.
If the queue remains under flow control state within the configured PFC deadlock detection time, it is considered that a PFC deadlock has occurred and a PFC deadlock restore process is required.

Example

• Configure the time interval of PFC deadlock detection.
