Configure Deep Buffer mode

By default, Deep Buffer mode is disabled. To configure Deep Buffer mode on a switch, enable the mode, save the configuration, and reload the switch for the feature to take effect.

NOTE Disable all the network QoS configurations; for example, PFC and LLFC, before configuring the Deep Buffer mode.

To configure Deep Buffer mode:

  1. Enable Deep Buffer mode in CONFIGURATION mode. 

    hardware deep-buffer-mode

    After you configure Deep Buffer mode, the system displays a warning stating that the configuration takes effect only after saving it in the startup configuration and reloading the switch.

    NOTE To disable Deep Buffer mode, use the no form of the command. Disabling Deep Buffer mode takes effect only after saving it in the startup configuration and reloading the switch.

  2. Save Deep Buffer mode in the startup configuration in EXEC mode. 

    write memory

  3. Reload the switch in EXEC mode.
