Access Type
The SaMOG Gateway supports the following access-types:
Ethernet over GRE (EoGRE)
PMIPv6
Layer3 IP (L3IP)
IP over VLAN (IPoVLAN)
IP over GRE (IPoGRE)
The SaMOG Gateway determines the NPU flow for a session using the configured
access-type
CLI command under
the TWAN Profile Configuration Mode. Although the SaMOG Gateway does not support a change in the access-type
mid-session, the SaMOG Gateway drops the previous session and the access request message when a change is the
access-type is detected, and the NPU flows are switched to the changed access-type.
