DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide Parameters CNPV-PRIORITY-VALUE admin-defense-mode {disable | interior | interior-ready | edge} alternate-priority PRIORITY-VALUE defense-mode-choice {admin | auto | comp} Specifies the IEEE 802.1p priority value to be the Congestion Notification Priority Value (CNPV). The valid priority range of CNPV is 0 to 7. (Optional) Specifies the CND defense mode for this CNPV on the interface. disable: The congestion notification capability is administratively disabled for this priority. interior: The priority parameter of frames input are not remapped to or from this priority, and the frames are transmitted without CN-TAG ; interior-ready: The priority parameter of frames input are not remapped to or from this priority, and CN-TAGs won't be stripped off when transmitting the frames; edge: The priority parameter of frames input at this priority are remapped to an alternate value, frames at other priorities are not remapped to this priority, and the frames are transmitted without CN-TAG . If not specified, the default defense mode is disable Specifies a priority value to which this priority value is to be remapped when the receiving frame with a dot1p priority equal to the specified CNPV at Edge port. The valid priority range is 0 to 7. If not specified, the default alternate priority is 0. Specifies how the default CND defense mode and alternate priority for this Congestion Notification Priority Value on this 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. comp: The default CND defense mode and alternate priority are determined by global setting. If not specified, the default defense mode choice is comp. Default Command Mode Command Default Level Usage Guideline None. Interface Configuration Mode. Level: 12. The command is available for physical port configuration. You need use the qcn cnpv command in the global configuration mode to assign the priority value as a CNPV at first. When you issue the command in the interface mode and specify a priority which has not been globally assigned as a CNPV an error message will be prompted. The interface CNPV configuration has higher precedence than global CNPV configuration. That means the modification of the interface CNPV configuration overrides the global CNPV configuration. If the qcn cnpv CNPV-PRIORITY-VALUE command is issued without any optional keywords, all the setting of the specified CNPV for the interface will be retained. If you want administratively deactivate the CNPV on the specified interface, you need to: • Use the optional keyword defense-mode-choice to set the defense mode choice to admin. • Use the optional keyword admin-defense-mode with the argument disable. The command only takes effect when the QCN is enabled globally. Example This example shows how to administratively assign the defense mode to interior for CNPV 2 at interface Gi1.1.
