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.

qcn cnpv (interface)
This command is used to configure the QCN settings in the interface configuration mode.
qcn cnpv
CNPV-PRIORITY-VALUE
[admin-defense-mode {disable | interior | interior-ready | edge} |
alternate-priority
PRIORITY-VALUE
| defense-mode-choice {admin | auto | comp}]
defense-mode-choice
{admin | auto}
(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
.
cp-creation {enable |
disable}
(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
None.
Command Mode
Global Configuration Mode.
Command Default Level
Level: 3.
Usage Guideline
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.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# qcn cnpv 2 defense-mode-choice admin
DXS-3600-32S(config)# qcn cnpv 2 admin-defense-mode edge
DXS-3600-32S(config)# qcn cnpv 2 alternate-priority 1
DXS-3600-32S(config)#
Example
This example shows how to delete the priority 2 from CNPV.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# no qcn cnpv 2
DXS-3600-32S(config)#
