CSM + QOS

[wim.juste]

Hi,

Is it possible to use QOS (marking) for all packets coming from CSM blade?

It looks like I can't apply a service-policy to the CSM port-channel.

Alternate solution: I can apply a service-policy to the transit vlan between MSFC and CSM.

But then: are the CSM port-channel/interfaces QOS PORT-BASED or QOS VLAN-BASED

Or are there other solutions?

Thanks!

Wim

Wim,

you can create a policy on the CSM and use the command 'set ip dscp ...'.

You will need to use policy for each vserver where you need to set the QOS.

Gilles,

2 questions:

- But then the DSCP will only be marked for the ip flow from CSM to ServerFarm? I'll need it to be marked for flows from CSM to client. (to pass wan-backbone)

- For the moment I use no policy's, but only the "default policy" to select a serverfarm.

Can I still use the default policy when using the policy to set the DSCP

example config:

----------------

policy TEST_1

set ip dscp 16

vserver T_TELNET_SV

virtual 10.33.36.39 tcp telnet

vlan 150

serverfarm T_TELNET_SF

persistent rebalance

slb-policy TEST_1

inservice

Greetings, Wim

1# the DSCP mark will be set on the server respones as well.

2# You need to add your serverfarm to the policy.
