I am trying to do some test of multicast in local network. The scenario I am trying to test is as follows:
1. Server 1 is the source of multicast traffic and it sends multicast to group 220.127.116.11. Server 2 is on the same VLAN and is able to receive multicast from group 18.104.22.168. Both Server 1 and Server 2 use iperf for the test.
2. Then I configured port mirroring on powerconnect 6248 switch. The source port is configured as the port Server 2 is connected, and destination port (which is on another VLAN) is the port another server (Server 3) is connected.
3. I am expecting to receive the same multicast on Server 3. However, I cannot receive any multicast either using iperf or tcpdump.
No multicast routing protocol configured. No igmp snooping enabled.
Any help is appreciated.
