Roadmap for Configuring SCU
date_range
24-Nov-23
To configure source class usage (SCU), you must:
Create a routing policy that includes prefix route filters that indicate the IPv4 or IPv6 source addresses to monitor. See Configuring Route Filters and Source Classes in a Routing Policy.
Apply the filters to the forwarding table. See Applying the Policy to the Forwarding Table.
Enable accounting on the inbound and outbound interfaces. See Enabling Accounting on Inbound and Outbound Interfaces.
