Method Detail

isTunnelPort

boolean isTunnelPort(org.projectfloodlight.openflow.types.DatapathId sw,
                     org.projectfloodlight.openflow.types.OFPort port)

Returns if a given switchport is a tunnel endpoint or not

getLinks

java.util.Map<Link,LinkInfo> getLinks()

Retrieves a map of all known link connections between OpenFlow switches and the associated info (valid time, port states) for the link.

getLinkInfo

LinkInfo getLinkInfo(Link link)

Retrieves the link info for a given link

Parameters:

link - link for which the link info should be returned

Returns:

the link info for the given link

getLinkType

ILinkDiscovery.LinkType getLinkType(Link lt,
                                    LinkInfo info)

Returns link type of a given link

Parameters:

info -

Returns:

generateLLDPMessage

org.projectfloodlight.openflow.protocol.OFPacketOut generateLLDPMessage(IOFSwitch iofSwitch,
                                                                        org.projectfloodlight.openflow.types.OFPort port,
                                                                        boolean isStandard,
                                                                        boolean isReverse)

Returns OFPacketOut which contains the LLDP data corresponding to switchport (sw, port). PacketOut does not contain actions. PacketOut length includes the minimum length and data length.

getSwitchLinks

java.util.Map<org.projectfloodlight.openflow.types.DatapathId,java.util.Set<Link>> getSwitchLinks()

Returns an unmodifiable map from switch id to a set of all links with it as an endpoint.

addListener

void addListener(ILinkDiscoveryListener listener)

Adds a listener to listen for ILinkDiscoveryService messages

Parameters:

listener - The listener that wants the notifications

getSuppressLLDPsInfo

java.util.Set<NodePortTuple> getSuppressLLDPsInfo()

Retrieves a set of all switch ports on which lldps are suppressed.

AddToSuppressLLDPs

void AddToSuppressLLDPs(org.projectfloodlight.openflow.types.DatapathId sw,
                        org.projectfloodlight.openflow.types.OFPort port)

Adds a switch port to suppress lldp set. LLDPs and BDDPs will not be sent out, and if any are received on this port then they will be dropped.

RemoveFromSuppressLLDPs

void RemoveFromSuppressLLDPs(org.projectfloodlight.openflow.types.DatapathId sw,

java.util.Set<org.projectfloodlight.openflow.types.OFPort> getQuarantinedPorts(org.projectfloodlight.openflow.types.DatapathId sw)

Get the set of quarantined ports on a switch

isAutoPortFastFeature

boolean isAutoPortFastFeature()

Get the status of auto port fast feature.

setAutoPortFastFeature

void setAutoPortFastFeature(boolean autoPortFastFeature)

Set the state for auto port fast feature.

Parameters:

autoPortFastFeature -

getPortLinks

java.util.Map<NodePortTuple,java.util.Set<Link>> getPortLinks()

Get the map of node-port tuples from link DB

addMACToIgnoreList

void addMACToIgnoreList(org.projectfloodlight.openflow.types.MacAddress mac,
                        int ignoreBits)

addMACToIgnoreList is a service provided by LinkDiscovery to ignore certain packets early in the packet-in processing chain. Since LinkDiscovery is first in the packet-in processing pipeline, it can efficiently drop these packets. Currently these packets are identified only by their source MAC address. Add a MAC address range to ignore list. All packet ins from this range will be dropped - use with care!

Parameters:

mac - The base MAC address that is to be ignored

ignoreBits - The number of LSBs to ignore. A value of 0 will add only one MAC address 'mac' to ignore list. A value of 48 will add ALL MAC addresses to the ignore list. This will cause a drop of ALL packet ins.
