comp
(*) The rule to automatically determine the alternate priority: An integer indicating the next lower priority
value than this CNPV that is not a CNPV in an end station or bridge component, or the next higher non-
CNPV, if all lower values are CNPVs.
For example, to administratively deactivate the CNPV on the specified interface:
•
Use the qcn cnpv interface configuration command with 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.
When a queue ID is used for a CNPV the switch will attach a Congestion Point (CP) on the corresponding
outbound queue for each port. When you set the defense mode to disabled for a CNPV on an interface, it
probably causes the congestion detection at the corresponding outbound queue on this interface be
disabled. In other words, the switch will disable the interface's corresponding CP function when this
interface has no active (non-disabled) CNPV mapped to that queue ID. For example, if a CNPV is only
enabled on a single interface and no other active (non-disabled) CNPVs use the same queue ID, it
implies the corresponding CPs on other egress ports are inactive then no CNMs can be triggered for the
incoming traffic from this single enabled interface. To make the Congestion Notification Domain (CND)
work correctly you need enable a CNPV on more than one interface.
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
Ethernet 1/0/1.
Switch# configure terminal
Switch(config)# interface ethernet 1/0/1
Switch(config-if)# qcn cnpv 2 defense-mode-choice admin
Switch(config-if)# qcn cnpv 2 admin-defense-mode interior
Switch(config-if)#
88-6 qcn cp
This command is used to configure the settings of the Congestion Point (CP).
qcn cp CP-QID {set-point QSP-VALUE | weight WEIGHT-VALUE | sample-base SAMPLE-BASE-
VALUE | min-header-octets MIN-HEADER-VALUE}
Parameters
CP-QID
set-point QSP-VALUE
Congestion Notification
TLV.
admin admin-defense-mode
(global)
auto Controlled by the LLDP
Congestion Notification
TLV.
Specifies the queue ID that the Congestion Point (CP) is attached to.
The relation between the queue ID and CP is one-to-one. The CP is
specified by the queue ID to which the CP is attached to.
Specifies the set point (cpQSp) in octets for the queue managed by
this CP. Congestion Notification Messages are transmitted to the
sources of the frames queued in this CP's queue in order to keep the
