2076 ExtremeWare 7.7 Command Reference Guide
IP Multicast Commands
The group IP address must be in the class-D multicast address space, but should not be in the multicast
control subnet range (224.0.0.x/24).
ExtremeWare based systems do not maintain packet forwarded statistics for each source/group
combination (S,G) and cannot return that information.
Example
The following command traces the multicast group 227.160.14.23 originating at 10.10.32.14 that is
coming through the gateway at 172.16.255.1:
mtrace source 10.10.34.14 group 227.160.14.23 gateway 172.16.255.1 mtrace source
3.3.3.200 group 225.1.1.1 gateway 22.22.22.9
Output from the command is similar to:
Mtrace from 10.10.34.14 to 172.16.255.2 via group 227.160.14.23
mtrace_send_query: Src:10.10.34.14, Grp:227.160.14.23, Dst:172.16.255.2,
Resp:172.16.255.2, to:172.16.255.1, from:172.16.255.2
mtrace_proc_resp: Src: 10.10.34.14, Dst: 172.16.255.2
