1) for QoS, which one better, configure inside CE or PE
2) Can we do QoS based on time/date. ie end of the month or after 6 pm, e-mail become silver ..other than that, e-mail traffic is precendence 0. And also bandwidth allocation. That means, middle of the month, gold is 40% and end of the month, gold is 15 %.
If yes, any good link/url for this. I think it can be done but just wanna get opinion/advice from u all.
You can use the modular QoS CLI to achieve this. You can create time based ACLs and use them in the policy-maps to set IP precedence or other parameters like MPLS EXP bits or DSCP values, based on which QoS treatment can be given to the traffic. Check out the 'Classification' and 'Modular QoS CLI' setions in this link :
