HP6120X叶片开关QoS

Question

我刚刚访问了刀片中心，我正在查看开关的配置，如下所示。

我可以看到交换机已经配置了QoS，我对QoS不是很精通，所以试图了解它到底配置了什么？

如果我想删除QoS，在惠普交换机上做什么命令，我很熟悉思科，但惠普对我来说是新的猛兽。

更新

在下面的命令输出中，确切地说，我的计划是将这个刀片中心用于VMWare，您认为下面的配置会在我的VMWare流量中造成任何问题吗？我对QoS知之甚少，所以我试着去理解影响。

swt-blade-1-a# show qos traffic-template egressdt

  TRAFFIC-TEMPLATE:   egressdt
  Status          :   Active

Queue                        Egress Discard
Number    Priorities         Threshold         Name
------    --------------     --------------    --------------------
1         0,1,2,3            Low               best-effort-tcg
2         4,5,6,7            High              control-tcg

Answer 1

删除QoS设置通常需要使用no预置语句，类似于思科设备。

qos dscp-map 111000 priority 7
qos dscp-map 110000 priority 6
qos dscp-map 101000 priority 5
qos dscp-map 100000 priority 4
qos dscp-map 011000 priority 3
qos dscp-map 010000 priority 2
qos dscp-map 001000 priority 1
qos dscp-map 000000 priority 0

这些线路将IP ToS不同的编码点映射到交换机的(802.1p)优先级。请注意，其他代码点可能已经具有默认优先级。您可以使用show qos dscp-map检查当前表。

qos queue-config 2-queues

将开关配置为使用2个队列(4是默认的，8也是可能的)。

qos traffic-template "egressdt"
   map-traffic-group 1 egress-discard-threshold low
   exit

为队列1创建低优先级的模板。

interface 1
   policy traffic-template "egressdt"
   ...
   exit
...

将模板应用于所需的接口。
