Multicast Routing Monitor

eparamo · ‎10-05-2007

Hi all,

I've set up a mrm test as described below:

Test Manager:

Manager:prueba/10.0.0.14 is running, expire:23:39:19

Beacon interval/holdtime/ttl:5/86400/32

Group:239.192.7.76, UDP port test-packet/status-report:16384/65535

Test senders:

10.0.0.15 /Ack

Test receivers:

10.12.70.189 /Ack 10.12.70.190 /Ack

Test receivers are getting multicast test packet:

deb udp

ct 5 12:01:33 CET: UDP: rcvd src=10.0.0.15(16384), dst=239.192.7.76(16384), length=24

Oct 5 12:01:33 CET: UDP: rcvd src=10.0.0.15(16384), dst=239.192.7.76(16384), length=24

And, of course, port 16384 is listening:

Prueba2#sh ip sockets

17 --listen-- 10.12.70.189 16384 0 0 1 0

So, it seems to work fine but the manager receive status report packet with 100% lost packets.

Receiver:10.12.70.189

Oct 5 09

Furthermore the time format is configured on the router in UTC+2 and the time show in the output is UTC.

Can anyone help me?

Thanks in advance.

If the Test Receiver detects an error it sends an error report to the router configured as the Manager. The Manager immediately displays the error report. (The show ip mrm status-report command also displays error reports, if any.) You then troubleshoot your multicast environment as normal, perhaps using the mtrace command from the source to the Test Receiver. If the show ip mrm status-report command displays no error reports, the Test Receiver is receiving test packets without loss or duplicates from the Test Sender. Here is an example and explanation on each field in sh ip mrm status-report: More information is available at the following URL
