Configuring the MultiNode Load Balancing Forwarding Agent

Enabling NetFlow Switching

You must enable NetFlow switching on all interfaces that will carry ContentFlow traffic. To enable NetFlow switching, use the following commands beginning in interface configuration mode:

	Command	Purpose
Step 1
	Router(config-if)# interface type	Specifies the interface, and enters interface
	slot/port-adapter/port	configuration mode.
	(Cisco 7500 series routers)
	or
	Router(config-if)# interface type slot/port
	(Cisco 7200 series routers)
Step 2
	Router(config-if)# ip route-cache flow	Enables flow switching on the interface.

Normally the size of the NetFlow cache will meet your needs. To increase or decrease the number of entries maintained in the cache, use the following command in global configuration mode:

Command	Purpose
Router(config)# ip flow-cache entries number	Changes the number of entries maintained in the
	NetFlow cache. The number of entries can be from
	1024 to 524288. The default is 64536.

Refer to the “Netflow Switching” part of the Cisco IOS Switching Services Configuration Guide for more information on how to configure NetFlow switching.

Enabling IP Multicast Routing

You must enable IP multicast routing on all interfaces to the services manager.

To enable multicast routing on all interfaces, use the following command in global configuration mode:

Command	Purpose
Router(config)# ip multicast routing	Enables multicast routing.

To have the router join a multicast group and enable IGMP, use the following command in interface configuration mode:

Command	Purpose
Router(config-if)# ip igmp join-groupgroup-address	Joins a multicast group. This command must be
	configured on all interfaces that will listen for the
	services manager multicasts. The group address
	must match that configured within the services
	manager configuration.
