Per SLA-profile instance accounting (with interim-updates) and per SLA-profile instance accounting (with interim-updates) with host accounting enabled is supported. The interim-updates are scheduled updates and carry IPv4 address and IPv6 address or prefix are assigned to the UE.
A sample sequence with per SLA-profile instance accounting (with interim-updates) is shown below:
0. IPv4oE host created based on DHCPv4.
1. Acct-start generated (contains framed-ip-address).
2. SLAAC host comes up.
3. Next scheduled interim-update (contains framed-ip-address and framed-IPv6-Prefix, that is, SLAAC-prefix).
4. DHCPv6 IA_NA gets assigned and corresponding host is created.
5. Next Scheduled interim-update (contains framed-ip-address, framed-IPv6-Prefix and Alc-Ipv6-Address).
6. SLAAC host times out.
7. Next Scheduled interim-update (contains only Alc-IPv6-Address and does not contain framed-IPv6-Prefix).
8. DHCPv6 IA_NA lease times out.
9. Next Scheduled interim-update (contains only framed-ip-address).
A sample sequence with per SLA-profile instance accounting (with interim-updates) with host accounting enabled is shown below:
0. IPv4oE host created based on DHCPv4.
1. Acct-start for sla-profile instance generated (contains framed-ip-address).
2. Acct-start for DHCPv4 host is generated (contains framed-ip-address).
3. SLAAC host comes up.
4. Acct-start for SLAAC host is generated (this should contain framed-IPv6-Prefix, that is, SLAAC-prefix)
5. Next scheduled interim-update for sla-profile instance accounting (contains framed-ip-address and framed-IPv6-Prefix, that is, SLAAC-prefix).
6. DHCPv6 IA_NA gets assigned and corresponding host is created.
7. Acct-start for DHCPv6 IA_NA host is generated (contains Alc-Ipv6-Address).
8. Next Scheduled interim-update (contains framed-ip-address, framed-IPv6-Prefix and Alc-Ipv6-Address).
9. SLAAC host times out.
10. Acct-stop (SLAAC-host-acct-session-id) is generated.
11. Next Scheduled interim-update for sla-profile instance accounting (contains only Alc-IPv6-Address).
12. DHCPv6 IA_NA lease times out.
13. Acct-stop (DHCPv6-IA_NA-host-acct-session-id) is generated.
14. Next Scheduled interim-update for sla-profile instance accounting (contains framed-ip-address).
15. DHCPv4 lease times out.
16. Acct-stop (DHCPv4-host-acct-session-id) is generated.
17. Acct-stop for sla-profile instance accounting is generated.
