Functions

func ITNexusPingCheck

func ITNexusPingCheck(initiatorPorts []*model.Network, targetPorts []*model.TargetPortal, pingCount, pingInterval, pingTimeout int) (map[*model.Network][]*model.TargetPortal, error)

ITNexusPingCheck takes an array of CHAPI2 initiator ports, and an array of target ports, and returns a map of IT nexus connections that can reach each other (e.g. ICMP ping test). Each IT nexus is pinged in parallel for maximum performance. The returned map key is the initiator port while the map value is an array of target ports.

func ITNexusSubnetCheck

func ITNexusSubnetCheck(initiatorPorts []*model.Network, targetPorts []*model.TargetPortal) (map[*model.Network][]*model.TargetPortal, error)

ITNexusSubnetCheck takes an array of CHAPI2 initiator ports, and an array of target ports, and returns a map of IT nexus connections that could be made. The returned map key is the initiator port while the map value is an array of target ports.
