Forwarding Scale Profiles Overview
Cisco ACI and APIC allow you to configure different Forwarding Scale Profiles to suit your topology and deployment use cases. This section describes all Forwarding Scale Profiles and their purpose. Keep in mind, specific profiles may be unavailable in earlier releases or restricted to specific hardware platforms. For detailed information on hardware support and scalability numbers of each profile, see the release-specific chapters.
-
Dual Stack—The default profile for all new supported switches that allows both IPv4 and IPv6 configurations.
-
High Dual Stack—Provides increased IPv4, IPv6, and policy scale numbers compared to the default Dual Stack profile. This profile supports different scalability limits based on the specific switch platforms.
-
High LPM—Provides scalability similar to the Dual Stack profile, but for deployments that require higher scale for longest prefix match (LPM) and lower policy scale.
-
High Policy—This profile is similar to the Dual Stack profile but with higher policy scale. This profile has specific hardware requirements.
-
IPv4 Scale—This profile is designed for IPv4-only deployments and allows you to configure higher IPv4 scale where no IPv6 configurations are needed.
-
High IPv4 EP Scale—This profile is recommended to be used only for the ACI border leaf (BL) switches in Multi-Domain (ACI-SDA) Integration. It provides enhanced IPv4 EP and LPM scales specifically for these BLs and has specific hardware requirements.
-
Multicast Heavy—This profiles provides an enhanced multicast scale and has specific hardware requirements.
