User-Based Rate Limiting in the Cisco Catalyst 6500

Tags: mpls

Overview When the Cisco Catalyst 6500 Series Supervisor Engine 720 was introduced, it brought with it a number of new features that used hardware advancements found in the Policy Feature Card 3 (PFC3). In contrast to major features such as IPv6 and MultiProtocol Label Switching (MPLS) that gained a lot of attention, User-Based Rate Limiting (UBRL) is one feature that is not as well known. UBRL is a form of microflow policing allowing the administrator to rate limit traffic flows, but unlike a normal microflow policer, it allows a policer to be applied to all traffic to or from a specific user. This paper will explore UBRL in more detail by providing information about how UBRL works and some examples.
