I have an ISP situation where there is about 1000 users sitting behind Cisco 3550 switches. Each port is 1 user and is configured with an individual VLAN where each VLAN is assigned a small network subnet and corresponding DHCP scope.
The problem is that it seems (so I have been told) is these 3550's will not effectively bandwidth limit at the port level. Incoming bandwith is limited as configured, but outgoing is not. So, I am looking at a pf solution but google is not turning up any specific information for such a situation. Ideally I would limit each subnet (and thus corresponding VLAN/Port/Customer) to what the customer is paying for (1Mb up/1Mb down, etc). Is anyone running 1000 different queues with pf? Any experience or suggestions on the performance and reliability? Is there another direction I should be looking to accomplish this? As an additional note: I don't need to do any traffic prioritization or QoS. Just raw limiting. It might be nice to allow bursting but it is not a requirement. Any info would be appreciated. Thanks, -Justin
