Hi guys,

Is there any recommendations about the size of the subnets used to communicate the supervisor 720 with the wism.

I think I will waste address, for example, if I use two subnets /24 for service vlan e ap-manager.

Thanks in Advanced,

Andre Lomonaco

Your subnet should be big enough to accomodate all the hosts which will need addresses. A /28 or /29 is probably plenty big for your service vlan.

On the other hand, RFC 1918 gives you close to 18 million addresses worthof private space to work with, so it's unlikely you're going to run out in most deployments.

Keep in mind these service vlans are local to the cat .... the service ports should never be seen by the management interfaces..
