Show Connected Multicasts
Jun 2017
To show if an interface is actively listening to any multicast streams, we can show this by using the netstat command: (netstat -ng)
netstat -ng IPv6/IPv4 Group Memberships Interface RefCnt Group --------------- ------ --------------------- lo 1 224.0.0.1 eth2 4 239.0.200.1 eth2 1 224.0.0.1 eth3 1 224.0.0.1 eth4 1 224.0.0.1 eth5 1 224.0.0.1 eth0 1 224.0.0.1 eth1 1 224.0.0.1 lo 1 ff02::1 eth2 1 ff02::1 eth3 1 ff02::1 eth4 1 ff02::1 eth5 1 ff02::1 eth0 1 ff02::1 eth1 1 ff02::1
This is a packager (v8) that I have setup a service on. That service is an ABR service containing four streams, so the line:
eth2 4 239.0.200.1\
Is interesting to me, I can see that from address 239.0.200.1 (the MFEL multicast output) Interface 2 is connected to four multicasts.
