Sembra certo che i dispositivi 802.1ad non popolano il tag esterno EtherType con 0x88A8. In user data
è necessaria una modifica speciale per l'interazione con questi dispositivi.
Supponendo che sia configurato un VRF di gestione con S-Tag:
20 e C-Tag:
100, modificare la sezione vrf_vlan in / etc
/ config
/ gatewayd
come indicato di seguito. Impostare inoltre resp_mode
su 1 in modo che SD-WAN Gateway esegua un controllo meno rigido per consentire i frame Ethernet che hanno il tag EtherType 0x8100 non corretto nell'intestazione esterna.
