we have Cisco Nexus 5K used as plane L2 switch. 1 multicast feed server & 4 receiver machines are connected to same switch port.
by default igmp snooping is enabled. observed receivers were unable to receive multicast feeds. but when i disabled igmp snooping globally receiver were able to receive multicast.
Q1. what can be causes so that after enabling igmp snooping receiver stops to receive traffic.
Q2. on layer 3, pim is enabled, i know command to check whether multicast is forwarded to receiver or not but on layer 2 switch how to check it.
also can you suggest me some nice simple document about working of multicast on L2 & L3 switches separately.
i have very basic knowledge of multicast, can you please tell me how to verify whether multicast traffic is received on feed server port on L2 switch... and whether multicast is forwarded to receiver or not.
