QoS Pass-Through Mode SNMP MIB Object. A read-write MIB object,
1.3.6.1.4.1.11.2.14.11.5.1.7.1.24.1, has been added to the ProCurve switch MIB. The QoS Pass-Through
Mode can be changed using either an SNMP network management application or the CLI setmib
command.
Syntax: setMIB hpSwitchQosPassThroughModeConfig.0 -i [ 1 | 2 | 3 | 4 ]
Specifies the QoS queue mode to be used by the switch. The number of queues and
the size of each queue is determined by the mode selected.

The following example changes the QoS Pass-Through Mode to one-queue. A show command verifies
the new mode.
ProCurve(config)# setMIB hpSwitchQosPassThroughModeConfig.0 -i 4
hpSwitchQosPassThroughModeConfig.0 = 4
ProCurve(config)# show qos-passthrough-mode
Qos passthrough mode : one-queue
ProCurve(config)#
Figure 2. Example Showing QoS Pass-Through Mode Set Using the setMIB Command
Displaying the Current QoS Pass-Through Mode on the Switch
The following command indicates the current QoS Pass-Through Mode on the switch.
Syntax: show qos-passthrough-mode
This command displays the current QoS Pass-Through Mode configured on the switch. The
default mode is typical.
optimized: Configures two QoS queues: a small queue for Priority 6 and
7 traffic and a large queue for all other traffic.
typical: Configures four QoS queues: a large queue for Priority 0 and 3
traffic, and three other queues for the remaining traffic. This is the
default configuration on the switch and is used when QoS Pass-
Through is disabled.
balanced: Configures four QoS queues of the same size. This configura-
tion is the same as was used by software versions prior to M.08.xx.
one-queue: Configures one QoS queue. By consolidating packet buffer
memory, line-rate flows with no loss of data may be achieved.
Note: This mode has a small queue used exclusively by Priority 7
management and control packets.
