mrinfo
This command is used to query the neighbor information of a multicast-capable router specified by
[ipaddr]. The default value is the IP address of the system at which the command is issued. The mrinfo
command can take up to 2 minutes to complete. Only one mrinfo command may be in process at a
time. The results of this command will be available in the results bufferpool which can be displayed by
using show mrinfo.
Syntax
mrinfo [ipaddr]
Default
none
Mode
Privileged Exec
mstat
This command is used to find the packet rate and loss information path from a source to a receiver
(unicast router id of the host running mstat). The results of this command will be available in the
results bufferpool which can be displayed by using show mstat. If a debug command is already in
progress, a message is displayed and the new request fails.
Syntax
mstat source [group] [receiver]
The source is the IP Address of the remote multicast-capable source. The receiver is the IP address of
the receiver. The default value is the IP address of system at which the command is issued. The group
is a multicast address of the group to be displayed.
Default

The default value of group is 224.2.0.1
Mode
Privileged Exec
mtrace
This command is used to find the multicast path from a source to a receiver (unicast router ID of the
host running mtrace). A trace query is passed hop-by-hop along the reverse path from the receiver to
the source, collecting hop addresses, packet counts, and routing error conditions along the path, and
then the response is returned to the requestor. The results of this command will be available in the
results buffer pool, which can be displayed by using show mtrace.
If a debug command is already in execution, a message is displayed and the new request fails.
Syntax
,Cs OE sourceipaddr [destination] [group]
The sourceipaddr is the IP Address of the remote multicast-capable source. The receiver is the IP
address of the receiver. The default value is the IP address of system at which the command is issued.
The group is the multicast address of the group to be displayed.
