Types

type Client

type Client struct {
	SwIfIndex        uint32
	Hostname         string
	ID               string
	WantDhcpEvent    bool
	SetBroadcastFlag bool
	PID              uint32
}

Client is helper struct grouping DHCP client data

type Dhcp

type Dhcp struct {
	Client *Client `json:"dhcp_client"`
	Lease  *Lease  `json:"dhcp_lease"`
}

Dhcp is helper struct for DHCP metadata, split to client and lease (similar to VPP binary API)

type HandlerVersion

type HandlerVersion struct {
	Msgs []govppapi.Message
	New  func(govppapi.Channel, logging.Logger) InterfaceVppAPI
}

type InterfaceDetails

type InterfaceDetails struct {
	Interface *interfaces.Interface `json:"interface"`
	Meta      *InterfaceMeta        `json:"interface_meta"`
}

InterfaceDetails is the wrapper structure for the interface northbound API structure.

type InterfaceEvent

type InterfaceEvent struct {
	SwIfIndex  uint32
	AdminState uint8
	LinkState  uint8
	Deleted    bool
}

InterfaceEvent represents interface event from VPP.
