Configures the OVSDB server in ExtremeXOS to establish connections to remote OVSDB controllers.
| schema | OVSDB schema. |
| hardware_vtep | Specifies Hardware VXLAN Tunnel End-Point (VTEP). |
| add | Add to the local OVSDB server. |
| delete | Delete from the local OVSDB server. |
| connection | Specifies OVSDB connection. |
| client | Initiates connection to remote server. |
| tcp | Specifies unencrypted TCP connection to remote server. |
| ssl | Specifies encrypted connection using SSL/TLS to remote server. |
| ipaddress remote_ip | Specifies IP address of the remote server. |
| port remote_port | Specifies TCP port number of the remote server (default is 6640). |
If you do not a specify a TCP port for the remote server, the default is 6640.
A switch in factory default configuration does not initiate connections to any remote OVSDB managers. At least one server or client connection must be added so that ExtremeXOS can be managed using OVSDB management protocol.
The OVSDB server in ExtremeXOS initiates the connections to managers listed in the relevant manager tables of the OVSDB database being served. For example, if the manager table in the Hardware VTEP database has an entry for TCP:172.16.19.21:6640, then ExtremeXOS initiates a connection to that IP address and port number.
When using SSL for OVSDB connections, an SSL certificate must be configured on ExtremeXOS. It is recommended that all CLI-configured OVSDB connections should be either client or server connections; client and server OVSDB connections should not be configured simultaneously.
The following example has OVSDB initiate SSL connections on TCP port 6632 and VLAN (Virtual LAN) with IP address 172.16.21.21:
configure ovsdb schema hardware_vtep add connection client ssl ipaddress 172.16.21.21 port 6632
The following example stops OVSDB from initiating (and also terminates any currently active) SSL connections configured in the previous example:
configure ovsdb schema hardware_vtep delete connection client ssl ipaddress 172.16.21.21 port 6632
This command was first available in ExtremeXOS release 22.1.
This command is supported on the Summit X770, X670-G2, and ExtremeSwitching X590, X690, X870 series switches, and stacks with X590, X770, X670-G2, X870, and X690 slots only.
