для Cisco Cisco Packet Data Gateway (PDG)
• when PDN is cleared
• The total current counter may be incremented/decremented multiple times during a PDN connection.
• The total setup counter is incremented multiple times during the PDN connection lifetime. For example,
every-time when the SOLICIT message is processed, the PD is successfully allocated to the UE.
• The total release counter is incremented multiple times during a PDN connection lifetime. For example,
everytime when the PD is released when DHCPv6 RELEASE message is processed from the UE and/or
PD is released due to VALID lifetime timer expiry event. Along with this Session Release Reasons:
(dhcp-prefix-delegation) counters are also incremented to the corresponding release reasons.

• Hence in case of delegate prefix allocation from the RADIUS server, Total Setup is equal to Total Current

This feature allows the User Equipment (UE) or a Customer Premises Equipment (CPE) to request the delegated
