vSphere API Release 5.0

Data Object Description

The VMwareVspanSession data object defines the configuration of a VLAN Services and Protocols for Advanced Networks (VSPAN) session. You use a VSPAN session for the following operations:

• To mirror network traffic (inbound/outbound) from a set of source entities to a set of destination entities.
• To assist in troubleshooting.
• As input for security and other network analysis appliances.

The type of entities that you can specify as source or destination is determined by the session type. You can use uplink distributed virtual ports only for mixed destination mirror VSPAN sessions (mixedDestMirror). For all sessions except mixedDestMirror sessions, you cannot use uplink distributed virtual ports as destination ports. sessionType is required for vSphere Distributed Switch 5.1 and later, ignored for prior version if set.

Session Type	Source	Destination
mixedDestMirror	Distributed Ports	Distributed Ports + Uplink Ports Name
dvPortMirror	Distributed Ports	Distributed Ports
remoteMirrorSource	Distributed Ports	Uplink Ports Name
remoteMirrorDest	VLAN	Distributed Ports
encapRemoteMirrorSource	Distributed Ports	IP address

Properties

Name	Type	Description
description*	xsd:string	The description for the session.
destinationPort*	VMwareVspanPort	Destination ports that received the mirrored packets. You cannot use wild card ports as destination ports. If wildcardPortConnecteeType is set in the value, the reconfigure operation will raise a fault. Also any port designated in the value of this property can not match the wild card source port in any of the Distributed Port Mirroring session.
enabled	xsd:boolean	Whether the session is enabled.
encapsulationVlanId*	xsd:int	VLAN ID used to encapsulate the mirrored traffic.
encapType*	xsd:string	Encapsulation type of the session. See VMwareDVSVspanSessionEncapType for valid values. Default value is encapProtocolGRE if unspecified in a VSPAN create operation. Since vSphere API Release 6.5
erspanCOS*	xsd:int	Class of Service of the monitored frame. Valid values are between 0 to 7, and default value is 0. This value is applicable only if encaptType is VspanSessionEncapType#erspan2 or VspanSessionEncapType#erspan3 Since vSphere API Release 6.5
erspanGraNanosec*	xsd:boolean	Timestamp Granularity. If the value is false, timestamp-granularity will be microsecond. Otherwise the timestamp-granularity will be nanosecond This value is applicable only if encaptType is VspanSessionEncapType#erspan3 Since vSphere API Release 6.5
erspanId*	xsd:int	ERSPAN ID of the session. Valid values are between 0 to 0x3ff, and default value is 0. This value is applicable only if encaptType is VspanSessionEncapType#erspan2 or VspanSessionEncapType#erspan3 Since vSphere API Release 6.5
key*	xsd:string	The generated key as the identifier for the session.
mirroredPacketLength*	xsd:int	An integer that describes how much of each frame to mirror. If unset, all of the frame would be mirrored. Setting this property to a smaller value is useful when the consumer will look only at the headers. The value cannot be less than 60.
name*	xsd:string	The display name.
netstack*	xsd:string	Netstack instance of the session. Since vSphere API Release 6.7
normalTrafficAllowed	xsd:boolean	Whether or not destination ports can send and receive "normal" traffic. Setting this to false will make mirror ports be used solely for mirroring and not double as normal access ports.
samplingRate*	xsd:int	Sampling rate of the session. If its value is n, one of every n packets is mirrored. Valid values are between 1 to 65535, and default value is 1. Since vSphere API Release 5.1
sessionType*	xsd:string	Type of the session. See VMwareDVSVspanSessionType for valid values. Default value is mixedDestMirror if unspecified in a VSPAN create operation. Since vSphere API Release 5.1
sourcePortReceived*	VMwareVspanPort	Source ports for which received packets are mirrored.
sourcePortTransmitted*	VMwareVspanPort	Source ports for which transmitted packets are mirrored.
stripOriginalVlan	xsd:boolean	Whether to strip the original VLAN tag. if false, the original VLAN tag will be preserved on the mirrored traffic. If encapsulationVlanId has been set and this property is false, the frames will be double tagged with the original VLAN ID as the inner tag.
