OVSDB Schema Table

OVSDB Schema Table

The CE switch can exchange data with the VMware NSX controller through the open vSwitch database (OVSDB) protocol. This data is stored in the form of tables in the OVSDB database. These tables are OVSDB schema tables. When both the CE switch and the VMware NSX controller serve as OVSDB clients, rows can be added in the OVSDB schema tables. Addition, deletion, and modification of rows can also be subscribed.

For example, the OVSDB client on the CE switch and the OVSDB client on the VMware NSX controller can respectively collect the MAC addresses learned by virtual tunnel end point (VTEP) devices on the physical and virtual networks and release them to corresponding OVSDB schema tables. Based on MAC addresses in the tables, the VTEP devices on the physical and virtual networks can determine how to transmit VM traffic.

Some OVSDB schema table names contain local and remote. For example, unicast MACs local table and unicast MACs remote table. The local table information is learned by the CE switch while the remote table information is learned by other software VTEPs.

Table 6-2 shows the OVSDB schema table supported by the CE switch.

Unicast MACs remote table

Unicast MAC address learned by the VTEP on a virtual network

VMware NSX controller

Unicast MACs local table

Unicast MAC address learned by the CE switch

CE switch

Multicast MACs remote table

One logical switch can only occupy one row. In this row, the MAC column contains the unknown dst keyword and a software VTEP list. This list includes a group of replicator nodes, which are used by the CE switch to process BUM packets.

VMware NSX controller

Multicast MACs local table

One logical switch can only occupy one row. In this row, the MAC column contains the unknown dst keyword and a hardware VTEP list.

CE switch

Tunnel table

Bidirectional forwarding detection (BFD) link information. This information is used to configure BFD for VXLAN on the CE switch and enable the CE switch to report BFD connection status.
