In this particular path, as long as the L2oGRE AP can be mapped to a configured
zone (based on IP address range), the UE packet will be accepted and forwarded.
The datacore verifies the unknown UE's coming from the AP in the L2oGRE LBO
zone before forwarding the UE packets. The following are the UE packet processing
steps.
1 UE associated with AP successfully is authenticated through 802.1X.
2 The authenticated UE traffic is sent to data plane through the L2oGRE tunnel.
3 The data blade receives the first UE packet (L2oGRE encapsulated). This could
either be the DHCP packet or any other IP packet (roaming to another data plane)
4 If the UE entry is not found, a message to GTpmgr is sent about the unknown
UE status.
5 GTpmgr sends an ICD message (D-C-DATA-TRIG-MSG) to the UE using the UE
Mac address.
6 The AUT indicates the UE is authenticated with the message C-D-DATA-TRIG-
MSG (status=22), The UE authentication state will be set to
UE_AUTH_NORMAL.
7 Subsequent UE packets are bridged out, VLAN/QinQ tagging rules will be as
per the configuration.
8 If the UE IP address is later identified, it is tracked through DHCP ACK. The AUT
will receive a D-C-NTFY-MSG, which include the UE IP address.
9 If the UE exists, the data plane UE entry is timed-out and marked as inactive.
The GTpmgr sends a D-C-NTFY-MSG (cause=1) to the AUT notifying the UE
timed out event.
10 If the UE returns or moves to another datablade, the status query process for
unknown UE is called again.
