This attribute controls which IP stack the Snmp component will use
to send and receive Snmp traffic for Communites and Parties whose
tdomain attribute specifies snmpUdpDomain as the transport
protocol.
If the value of this attribute is vrIp then Snmp Udp traffic will be
sent and received using Ip as provisioned under the VirtualRouter.
This requires provisioning of the ip feature.
If the value of this attribute is ipiFrIpiVc then Snmp Udp traffic
will be sent and received using IpiFr (Ip over Frame Relay) or IpiVc
(Ip over Vc), whichever is provisioned. This requires provisioning
of one of the ipiVc or ipiFr features.
