Are there any generel recommendations on how many class-maps a multi-match policy should contain? In this particular case, my multi-match policy will contain some 60+ class'es, as each customer has somewhere between 3 and 5 public ip's and traffic to theese ip's has to be matched and handled uniquely.

there is no specific recommendation on the max number of class-maps.

However, it is good to know that having one policy or multiple will be the same.

But usually, when there is unfortunately a hick and something does not work, the first solution is usually to remove the faulty policy and re-add it.

If you have only one policy, it means that during this operation all your clients will be affected.

With one policy per client, you can guarantee that you can add/remove one client without impacting the others.

Hi Gilles,

Thanks. I'll take that under consideration, when writing my config.
