Description
The mtrace command tracks the multicast path from a source to a receiver. A trace
probe is sent in a reverse path from the receiver back to the source. As the probe passes
from hop to hop, it collects information such as interface address and packet counts
from each router. If the mtrace command is executed with only the source parameter
then a multicast path is calculated from the source to the SSR. One can examine the
multicast path between two external hosts by specifying a receiver instead of using the
SSR as the default receiver.
Parameters
<source>
IP address of the source.
destination
<IPaddr>
Destination IP address.
group
<IPaddr>
Multicast destination group address.
max-hops
<number>
Maximum number of hops to trace (default: 0, range:
0-32)
Restrictions
None.
