Here is an example https://supportforums.cisco.com/docs/DOC-1230

And in the ACLs, as halijen said you should use the time range option.

I hope it helps.

PK

On CSM: Firewall --> Access Rules --> Add a new ACL/ACE --> click on the "Advanced" button --> there would be "Time Range" option to configure time range.

Thanks for the answer

Probably I misunderstand something

You wrote about time range in Access rule, and I really see this option in Access rule in CSM

But when I define QoS - I define  Access control list, Traffic flow and then I define QoS in
CSM --> PIX/ASA/FWSM Platform --> Service Policy Rules  --> IPS, QoS and Connections Rules

And I didn't find option to define time range not in ACL, not in Traffic flow and not in QoS options

You are absolutely right. I have just double checked that in the lab, and there is no time-range option for QoS on CSM.

You might want to open a TAC case for that.
