Testing Multicast

I know you can test multicast using a Windows resource tool called MCAST.EXE.  My problem is what is the proper syntax so I can run the app?
Thanks

Mcast.exe:
The Multicast Packet Tool can be used to send multicast packets or to listen for packets being sent to a multicast group address. Mcast is used to test multicast connectivity between computers on your network. Works in Windows XP/2003.

Switches:
/send > Sends packets out on the network.

/srcs:SourceAddress > Specifies the address(es) that are listed as the source in the sent multicast packets; this is a mandatory argument for the /send operation. Separate multiple source IP addresses with a comma.

/grps:GroupAddress > Specifies the multicast group address to which packets should be sent or from which packets should be received; this is a mandatory argument for both the /send and /recv operations.

/intvl:[PacketInterval] > Specifies the interval between sent packets, in milliseconds. If omitted, the default setting is 10.

/numpkts:[NumberPackets] > Specifies the number of packets to be sent from each source address provided to each group address provided. If omitted, the default setting is 100.

/ttl:[TimeToLive] > Specifies the time-to-live value of sent packets. If omitted, the default setting is 5.

/pktsize:[PacketSize] > Specifies the size of sent packets in bytes. If omitted, the default setting is 256.

/intf:[IPAddress] > Specifies the local interface to use for the Mcast tests. By default, Mcast uses the local adapter that is assigned the IP address specified in the Mcast packets.

/recv > Listens for multicast packets.

/dump:[packettype] > Displays the contents of received packets. Packettype specifies which packet types to display. If /dump: is omitted, the contents of the packet do not display. Valid packet types are:

1 - bad packets

2 - good packets

3 - all packets

/runtime:[Duration] > Specifies, in minutes, the duration for which Mcast should run. If omitted, Mcast continues to run until manually stopped.

ASKER

Yes, Ive seen this already..but, I want to know the syntax

ie   mcast.exe/GRPS:233.75.215.172

I know the above syntax is giving me a error message. So, im sure I have the incorrect syntax.  I want to seen multicast joins to a group using mcast.exe.
