Are Level One/Edgecore switches IPv6 enabled?
GEP-0522 is an unmanaged switch belonging to Layer 2 (OSI Model) mac layer.
IPv6 is layer 3. So there is no need to enable the switch IPv6 on it. GEP-0522 just stores and forwards Ethernet packets with IPv6. So any Layer 2 switch will be able to perform with IPv6.
