Do the Catalyst 4500/4000 switches that run CatOS support rate-limiting or policing on ports or VLANs?
A. Catalyst 4500/4000 switches that run CatOS do not provide policing or rate-limiting on Layer 2 (L2) ports. Rate-limiting is supported on Layer 3 (L3) Gigabit Ethernet interfaces. Refer to the Installation and Configuration Note for the Catalyst 4000 Layer 3 Services Module for additional information. Policing is supported on the Catalyst 4500/4000 switches that run Cisco IOS Software. For more information, refer to the document QOS Policing and Marking with Catalyst 4000/4500 IOS-Based Supervisor Engines.
