Forwarding Scale Profile Policy Overview
The Forwarding Scale Profile policy provides different scalability options. For example:
-
Dual Stack—provides scalability of up to 12,000 endpoints for IPv6 configurations and up to 24,000 endpoints for IPv4 configurations.
-
High LPM—provides scalability similar to the dual-stack profile, except that the longest prefix match (LPM) scale is 128,000 and the policy scale is 8,000.
-
IPv4 Scale—enables systems with no IPv6 configurations to increase scalability to 48,000 IPv4 endpoints.
-
High Dual Stack—provides scalability of up to 64,000 MAC endpoints and 64,000 IPv4 endpoints. IPv6 endpoint scale can be 24,000/48,000, depending on the switch hardware model.
Note
With Cisco Application Policy Infrastructure Controller (APIC) release 3.2(1), depending on your TOR switch hardware, a Forwarding Scale Profile with the High Dual Stack option has different scales; for example:
-
For Cisco Nexus 9000 Series TOR switches with FX in the switch name, the high dual-stack option has scalability of 48,000 IPv6 endpoints instead of 24,000 and 128,000 policies instead of 8,000.
-
For Cisco Nexus 9000 Series TOR switches with EX in the switch name, the high dual-stack option has the same scale values as with earlier Cisco APIC releases.
See the following table for more details.
