Disconnects the switch from the controller by setting the incorrect port

Executes ovs-vsctl show command and returns stdout, no check nor change is performed

Returns controllers uuid

Count the number of dump flows for a given table id and grep with port_mac if provided

Gets controller which is a master

Returns the controllers role

Get local ip of compute node ovsdb

Gets ovs data and parse them.

Return packet count for the specific table no.

Capture packetcount for IP in Table

Returns a list of ips of slave nodes for particular switch

This is a private keyword to enable diconnected controllers

This is a private keyword, verification is not reliable yet, enables disconnected controllers

Return is_connected boolean value

Private keyword, the existence of master means it is verified

Reconnects the switch back to the controller by setting the correct port

Adds controller to the bridge

The idea of this keyword is to setup clustered controller and to be more or less sure that the role is filled correctly. The problem is when more controllers are being set up at once, the role shown in Controller ovsdb table is not the same as we can see from wireshark traces. Now we set disconnected controllers and we will connect them expecting that the first connected controller will be master.

Check if the switch is connected

Check if the switch is disconnected

Verifies the master role

Verifies the slave role

Get ovs version and verify greater than required version
