DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide defense-mode-choice {admin | auto} cp-creation {enable | disable} (Optional) Specifies how to choose CND defense mode and alternate priority for this Congestion Notification Priority Value on all ports. This setting can be overridden by defense-mode-choice of per-interface. admin: The default CND defense mode and alternate priority are specified by administrator. auto: The default CND defense mode and alternate priority are controlled automatically. If not specified, the default defense mode choice is auto. (Optional) Specifies the default value for defense mode for newly-created port entries. enable: Newly-created port entries take the defense mode by global setting disable: Newly-created port entries take the defense mode by itself settings. If not specified, the default cp-creation is enable. Default Command Mode Command Default Level Usage Guideline None. Global Configuration Mode. Level: 3. Use this command to specify the priority to be the Congestion Notification Priority Value (CNPV) and configure the setting for this CNPV. If the qcn cnpv CNPV-PRIORITY-VALUE command is issued without any optional keywords: • If the specified CNPV-PRIORITY-VALUE is CNPV, all the configured settings will be retained. • Else if the specified CNPV-PRIORITY-VALUE is not CNPV, the specified CNPV-PRIORITY-VALUE is assigned as a CNPV and the corresponding settings will be filled with the default value. When an IEEE 802.1p priority is assigned as CNPV globally, the CNPV configuration for all interfaces will be created with default value. When a priority is deleted from CNPV, the CNPV configuration for all interfaces will be deleted. The command only takes effect when the QCN is enabled globally. The command qcn cnpv in interface configuration mode has higher precedence. According to IEEE 802.1Qau, up to seven entries can be active in the global CNPV table. If the maximum number of the table is reached, an error message will be issued when adding a new priority as CNPV. Example This example shows how to configure the priority 2 as CNPV and administratively assigns the defense mode for all ports as Edge. It assigns the default alternate priority to 1 for all other ports.
