Configuring PTSP Service Rules
PTSP policies can be downloaded dynamically from the external policy manager (such as SRC) or configured statically on the router. The PTSP policies can be configured for each distinct IPv4 source address for a given interface on which the service is configured. Each distinct IPv4 address is considered a subscriber and all PTSP policies are applied on a per-subscriber basis.
Dynamic policies, which are always specific to a subscriber, take precedence over static policies. When you download a new dynamic policy, it takes effect only for new flows. All new flows and TCP connections use the new dynamic policy. Existing flows are not affected by the new policy unless they timeout, after which they are considered a new flow.
To configure the PTSP policies, perform these tasks:
- To download dynamic policies and to collect statistics with Diameter, configure the Diameter application for PTSP. See Configuring the PTSP Application.
- To configure static policies, see Configuring Static PTSP Rules. To collect statistics in a flat file, see Configuring a Statistics Profile for PTSP.
