Access modes of VSIs

The access mode of a VSI determines how the VTEP processes the 802.1Q VLAN tags in the Ethernet frames.

VLAN access mode

In this mode, Ethernet frames received from or sent to the local site must contain 802.1Q VLAN tags.

In this mode, VXLAN packets sent between sites do not contain 802.1Q VLAN tags. You can use different 802.1Q VLANs to provide the same service in different sites.

By default, the access mode of a VSI is VLAN. The following sections describe traffic forwarding processes in VLAN access mode.

Ethernet access mode

The VTEP does not process the 802.1Q VLAN tags of Ethernet frames received from or sent to the local site.

In Ethernet access mode, VXLAN packets sent between VXLAN sites contain 802.1Q VLAN tags. You must use the same VLAN to provide the same service between sites.
