Describes the collection of billing statistics from ports configured for routed connectivity to external networks as a shared service in ACI.
Routed connectivity to external networks as a shared service billing and statistics is a ACI feature that
-
enables collection of byte count and packet count billing statistics from ports configured for routed connectivity to external networks as a shared service
-
allows any EPG in any tenant to share an external L3Out EPG for routed connectivity to external networks
-
aggregates billing statistics at the Cisco APIC from leaf switches where external L3Out EPGs are provisioned, and
-
supports periodic export of billing statistics to a server through configurable accounting policies.
External network representation and billing collection
The Cisco Application Policy Infrastructure Controller (APIC) can be configured to collect billing statistics from ports configured for routed connectivity to external networks as a shared service. External networks are represented as external L3Out endpoint group (l3extInstP managed object) in Cisco Application Centric Infrastructure (ACI).
Billing statistics can be collected for each EPG in any tenant that uses an external L3Out EPG as a shared service. The leaf switch where the external L3Out EPG is provisioned forwards the billing statistics to the Cisco APIC where they are aggregated. Accounting policies can be configured to export these billing statistics periodically to a server.
