This tab defines multicast configuration attributes for a JMS topic. After defining a JMS server, you can configure its topics. You can configure one or more topics for each JMS server.

Note: You configure destinations explicitly or by configuring a JMS template that can be used to define multiple destinations with similar attribute settings, as described in JMS Template Tasks.

Attribute Label	Description	Value Constraints
Multicast Address	The multicast address used by the destination. The IP address used for multicasting. This address is used to transmit messages to multicast consumers. MBean: weblogic.management. configuration. JMSTopicMBean Attribute: MulticastAddress	Configurable: yes Readable: yes Writable: yes
Multicast TTL	The number of network hops that a multicast message is allowed to travel. This is the Time-To-Live value used for multicasting, which specifyies the number of routers that the message can traverse enroute to the consumers. A value of 1 indicates that the message will not traverse any routers and is limited to one subnet. This value is independent of the JMSExpirationTime value. MBean: weblogic.management. configuration. JMSTopicMBean Attribute: MulticastTTL	Minimum: 0 Maximum: 255 Default: 1 Configurable: yes Readable: yes Writable: yes
Multicast Port	The multicast port for the destination. This is the IP port used for multicasting. This port is used to transmit messages to multicast consumers. MBean: weblogic.management. configuration. JMSTopicMBean Attribute: MulticastPort	Minimum: 1 Maximum: 65535 Default: 6001 Configurable: yes Readable: yes Writable: yes
