I just got access of blade center and i was looking at configuration of switch which is following.

I can see switch has already QoS configured, I am not very expert in QoS so trying to understand what exactly its configured?

If i want to remove QoS what are the commands to do that on HP switch, I am familiar with Cisco but HP is new beast for me.

swt-blade-1-a(config)# sh run

Running configuration:

UPDATE

In following command output, what exactly its saying, My Plan is to use this blade center for VMWare do you think following config will create any issue in my VMWare traffic? I have little knowledge of QoS so trying to understand impact.

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

  TRAFFIC-TEMPLATE:   egressdt
  Status          :   Active

Queue                        Egress Discard
Number    Priorities         Threshold         Name

2         4,5,6,7            High              control-tcg

Removing the QoS settings usually involves the statement with a no prepended, similar to Cisco devices.

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

These lines map IP ToS diffserve codepoints to the switch's (802.1p) priorities. Note that other codepoints may already have a default priority. You can check the current table with show qos dscp-map.

qos queue-config 2-queues

Configures the switch to use 2 queues (4 is default, 8 is also possible).

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

Creates a template with low priority for queue 1.

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

Applies the template to the desired interfaces.

You can find more details in the HP ProCurve Series 6120 Blade Switches Advanced Traffic Management Guide which apparently can't be linked here.

  • I have tired no policy traffic-template "egressdt" but its not letting me do that, i have tired on no qos traffic-template "egressdt" same error its saying it has been in used. I will get you more details once i close to computer – Satish Jul 31 '18 at 20:25
  • You cannot delete a template that's in use. You need to remove the template assignment from each interface first, then you can delete the unused template. – Zac67 Jul 31 '18 at 20:29
  • I am not seeing any option to delete template assigned to each interface... see this link i am inside interface-12 and no ? not seeing any option to delete. i have tired no qos also but nothing changed. pastebin.com/ri4n4qmA – Satish Jul 31 '18 at 20:51
  • no interface all policy traffic-template doesn't work? A template can only be applied to to all ports. This is surely true for removing it as well but I can't see that in the manual. It's possible that a template needs to be applied at all times, so you'd create and apply another one. – Zac67 Aug 1 '18 at 5:14
  • no interface all ? has following command pastebin.com/PWDi4Cf3 – Satish Aug 1 '18 at 17:20
