This RA can monitor physical interfaces, bonds, bridges, vlans and (hopefully) any combination of them. Examples: *) Bridge on top of one 10Gbps interface (eth2) and 802.3ad bonding (bond0) built on two 1Gbps interfaces (eth0 and eth1). *) Active-backup bonding built on top of one physical interface and one vlan on another interface. For STP-enabled bridges this RA tries to some-how guess network topology and by default looks only on ports which are connected to upstream switch. This can be overridden by 'bridge_ports' parameter. Active interfaces in this case are those in "forwarding" state. For balancing bonds this RA summs speeds of underlying "up" slave interfaces (and applies coefficient 0.8 to result). For non-balancing bonds ('active-backup' and probably 'broadcast'), only the speed of the currently active slave is used. Network interface speed monitor The name of the attribute to set. This is the name to be used in the constraints. Attribute name Network interface to monitor. Network interface Try to detect interface name by detecting the interface that holds the IP address. The IPv4 (dotted quad notation) or IPv6 address (colon hexadecimal notation) example IPv4 "192.168.1.1". example IPv6 "2001:db8:DC28:0:0:FC57:D4C8:1FFF". IPv4 or IPv6 address If not null and OCF_RESKEY_iface is a bridge, list of bridge ports to consider. Default is all ports which have designated_bridge=root_id. Bridge ports Relative weight of 1Gbps in interface speed. Can be used to tune how big attribute value will be. Weight of 1Gbps The time to wait (dampening) for further changes to occur.
