Interface LinkInfo

All Known Implementing Classes:

LinkInfoDTO

public interface LinkInfo

Represents the link status and the time of discovery of a layer 2 link in the network. The implementation is mutable and hence not thread-safe.

Method Summary

Methods

Modifier and Type	Method and Description
Set<PortState>	dstPortState() Returns the state of the destination port of the associated link.
long	multicastDiscoveryTime() Returns the time at which the direct link was discovered by means other than standard LLDP packet.
Set<PortState>	srcPortState() Returns the state of the source port of the associated link.
Link.Type	type() Returns the type of the associated link, i.e.
long	unicastDiscoveryTime() Returns the time at which the direct link was discovered.
void	updateDstPortState(Set<PortState> portState) Updates the state of the destination port of the associated link.
void	updateMulticastDiscoveryTime(long multicastDiscoveryTime) Updates the time at which the direct link was discovered by means other than standard LLDP packet, with the specified value.
void	updateSrcPortState(Set<PortState> portState) Updates the state of the source port of the associated link.
void	updateUnicastDiscoveryTime(long unicastDiscoveryTime) Updates the time at which the direct link was discovered with the specified value.

Method Detail

unicastDiscoveryTime

long unicastDiscoveryTime()

Returns the time at which the direct link was discovered.

The term unicast may be slightly misleading here; the standard LLDP destination MAC address that is currently used is a multicast address, however since this address is specified in the standard, we expect all switches to absorb the standard packet, thus making the standard LLDP packet describe only one link.

Returns:

the time of discovery of the associated link

multicastDiscoveryTime

long multicastDiscoveryTime()

Returns the time at which the direct link was discovered by means other than standard LLDP packet. For example, from a BDDP packet.

Returns:

the time of discovery of the associated link

srcPortState

Set<PortState> srcPortState()

Returns the state of the source port of the associated link.

Returns:

the state of the source port

dstPortState

Set<PortState> dstPortState()

Returns the state of the destination port of the associated link.

Returns:

the state of the destination port

type

Link.Type type()

Returns the type of the associated link, i.e. a direct link, multi-hop link or a tunnel.

Returns:

the type of the associated link

updateUnicastDiscoveryTime

void updateUnicastDiscoveryTime(long unicastDiscoveryTime)

Updates the time at which the direct link was discovered with the specified value.

Parameters:

unicastDiscoveryTime - the time of discovery to set

updateMulticastDiscoveryTime

void updateMulticastDiscoveryTime(long multicastDiscoveryTime)

Updates the time at which the direct link was discovered by means other than standard LLDP packet, with the specified value.

Parameters:

multicastDiscoveryTime - the time of discovery to set

updateSrcPortState

void updateSrcPortState(Set<PortState> portState)

Updates the state of the source port of the associated link.

Parameters:

portState - the state of the source port

Throws:

NullPointerException - if portState is null

updateDstPortState

void updateDstPortState(Set<PortState> portState)

Updates the state of the destination port of the associated link.

Parameters:

portState - the state of the destination port

Throws:

NullPointerException - if portState is null
