Cisco Systems 78-11741-02 manual MRM Configuration Task List, Restrictions, IPC-522

Using IP Multicast Tools

MRM Configuration Task List

•Can verify a multicast environment prior to an event—You need not wait for real multicast traffic to fail in order to find out that a problem exists. You can test the multicast routing environment before a planned event.

•Easy diagnostics—The error information is easy for the user to understand.

•Scalable—This diagnostic tool works well for many users.

Restrictions

You must make sure the underlying multicast forwarding network being tested has no access lists or boundaries that deny the MRM data and control traffic. Specifically, consider the following factors:

•MRM test data are User Datagram Protocol (UDP) and Real-Time Transport Protocol (RTP) packets addressed to the configured multicast group address.

•MRM control traffic between the Test Sender, Test Receiver, and Manager is addressed to the 224.0.1.111 multicast group, which all three components join.

MRM Configuration Task List

To configure and use the MRM feature, perform the required tasks described in the following sections:

•Configuring a Test Sender and Test Receiver (Required)

•Configuring a Manager (Required)

•Conducting an MRM Test (Required)

Configuring a Test Sender and Test Receiver

To configure a Test Receiver on a router or host, use the following commands beginning in global configuration mode:

	Command			Purpose
Step 1
	Router(config)# interface		type number	Specifies an interface.
Step 2
	Router(config-if)#	ip mrm	test-receiver	Configures the interface to be a Test Receiver.
Step 3
	Router(config)# ip	mrm accept-manager		Optionally, specifies that the Test Receiver can accept status
	{access-list}			report requests only from Managers specified by the access list.

To use MRM on test packets instead of actual IP multicast traffic, use the following commands beginning in global configuration mode to configure a Test Sender on a different router or host from where you configured the Test Receiver:

	Command			Purpose
Step 1
	Router(config)# interface		type number	Specifies an interface.
Step 2
	Router(config-if)#	ip mrm	test-sender	Configures the interface to be a Test Sender.
Step 3
	Router(config)# ip	mrm accept-manager		Optionally, specifies that the Test Sender can accept status report
	{access-list}			requests only from Managers specified by the access list.
