3.2.3 Rate Limiting
IVD supports rate-limiting function in input/output both direction.
Input Rate Limiting (IRL) on a per-AAL5 interface.
Output Rate Limiting (ORL) on a per ATM-port basis
Output Rate Limiting (ORL) on a per-physical Ethernet Interface basis.
One feature supports for buffer admission control triggered using IRL. Moreover, it also supports
for dynamic modification of ORL on ATM and Ethernet interfaces.
3.2.4 Mapping Table
IVD supports a packet priority to traffic class mapping table supported on a per egress bridge port.
3.2.5 Multiple Mechanisms
IVD supports two multiple mechanisms as below.
Multiple mechanisms of prioritizing incoming traffic are based on a per-bridge port.
(1) Using Source Port configuration (for untagged packets)
(2) Using Packet Classifier actions
(3) Using priority regeneration table (mapping ingress priority to egress priority)
(4) Combination of the above
Multiple mechanisms of 802.1p re-tagging of outgoing traffic is based on a per ingress bridge port.
(1) Using Source Port configuration (for untagged packets)
(2) Using Classifier actions
(3) Using priority regeneration table (mapping ingress priority to egress priority)
(4) Combinations of the above
3.2.6 Abilities
IVD can be able to create multiple scheduling profiles, either Strict Priority or Probabilistic Priority.
It also can be able to share the same profile across multiple (similar) ports.
3.3 Security
IVD supports some different methods to implement this feature in following sections.
3.3.1 Static Mac Address
IVD supports this feature to be configured with certain ports to learn MAC addresses on a semi-
permanent basis. These learned entries would be treated similar to the static entries, but will not
be subject to aging or overwriting. These only may be deleted explicitly by management or by
making the ports, as non-static after aging will happen normally.
