When using Identity Agent:
Packet tagging information, such as authentication key and encryption algorithm is propagated to PEP during session publishing only in 2 cases:
- when '
PacketTaggingAck' is received
- when packet tagging key is revoked
In all other cases, packet tagging information is not published. As a result, authentication key and encryption algorithm are not defined in PEP, and the rules with packet tagging Roles are not enforced.
When Identity Agent is not used:
In a multi-core gateway, there might be a case where the PEP daemon sends a request to unregister a network and at same time send a request to register a network, from a different core instance.
PDP might respond that the register command was not received.
