public OVXPort(int tenantId,
       PhysicalPort port,
       boolean isEdge,
       short portNumber)
        throws IndexOutOfBoundException

Throws:

IndexOutOfBoundException

OVXPort

public OVXPort(int tenantId,
       PhysicalPort port,
       boolean isEdge)
        throws IndexOutOfBoundException

Throws:

IndexOutOfBoundException

Method Detail

getTenantId

public Integer getTenantId()

getPhysicalPort

public PhysicalPort getPhysicalPort()

getPhysicalPortNumber

public Short getPhysicalPortNumber()

isActive

public boolean isActive()

isLink

public boolean isLink()

sendStatusMsg

public void sendStatusMsg(OFPortStatus.OFPortReason reason)

register

public void register()

Registers a port in the virtual parent switch and in the physical port.

virtualizePortStat

public void virtualizePortStat(OVXPortStatus portstat)

Modifies the fields of a OVXPortStatus message so that it is consistent with the configs of the corresponding OVXPort.

Parameters:

portstat - the virtual port status

applyPortStatus

public void applyPortStatus(OVXPortStatus portstat)

Changes the attribute of this port according to a MODIFY PortStatus.

Parameters:

portstat - the virtual port status

boot

public void boot()

tearDown

public void tearDown()

unregister

public void unregister()

getDBIndex

public Map<String,Object> getDBIndex()

Specified by:

getDBIndex in interface Persistable

Overrides:

getDBIndex in class Port<OVXSwitch,OVXLink>

getDBKey

public String getDBKey()

Specified by:

getDBKey in interface Persistable

Overrides:

getDBKey in class Port<OVXSwitch,OVXLink>

getDBName

public String getDBName()

Specified by:

getDBName in interface Persistable

Overrides:

getDBName in class Port<OVXSwitch,OVXLink>

getDBObject

public Map<String,Object> getDBObject()

Specified by:

getDBObject in interface Persistable

Overrides:

getDBObject in class Port<OVXSwitch,OVXLink>

equals

public boolean equals(OVXPort port)

unMap

public void unMap()

Undoes mapping for this port from the OVXSwitch and PhysicalPort.

unMapHost

public void unMapHost()
               throws NetworkMappingException

Removes a host from this port, if it's an edge.

Throws:

NetworkMappingException

handlePortDelete

public void handlePortDelete(OVXPortStatus stat)
                      throws NetworkMappingException

Deletes this port after removing any links mapped to this port. TODO see if this can be consolidated with unregister(), because it shares a lot in common

Parameters:

stat - PortStatus triggering port deletion

Throws:

NetworkMappingException

LinkMappingException

handlePortDisable

public void handlePortDisable(OVXPortStatus stat)
                       throws NetworkMappingException

Checks if this port has associated OVXLink(s) and/or SwitchRoute(s) and attempts to neatly disable them. This port and its neighbor are NOT deleted. Since this port is an end point, OVXLink/SwitchRoute, there is no real backup to recover to in this case, so we don't try.

Parameters:

stat - PortStatus triggering link down

Throws:

NetworkMappingException

handleLinkDisable

public void handleLinkDisable(OVXPortStatus stat)
                       throws NetworkMappingException

Disables a link for LINK_DOWN or DELETE PortStats. Mapping s for the OVXLink are removed only if the provided PortStat is of reason DELETE.

Parameters:

stat - the port status

Throws:

NetworkMappingException

handleRouteDisable

public void handleRouteDisable(OVXPortStatus stat)

Removes SwitchRoutes from a BVS's routing table if the end points of the route are deleted.

Parameters:

stat -

handlePortEnable

public void handlePortEnable(OVXPortStatus stat)
                      throws NetworkMappingException

Brings a disabled port and its links (by association up). Currently it's only the matter of setting the endpoints to nonEdge if they used to be part of a link.

Parameters:

stat - PortStatus indicating link up

Throws:

NetworkMappingException

hashCode

public int hashCode()

Overrides:

hashCode in class Port<OVXSwitch,OVXLink>

equals

public boolean equals(Object obj)

Overrides:

equals in class Port<OVXSwitch,OVXLink>

toString

public String toString()

Overrides:

toString in class Port<OVXSwitch,OVXLink>
