M4300 multicast issues
I have 2 m4300-48x switches stacked. 3 servers each have 2 nics connected to 1 port on each of the stacked switches. The 2 ports are in an LACP lag. Lags are up, ports are up. All multicast setti...
OSPF multicast works with the current config, but other multicast is being blocked. Same result on a single switch with one ethernet connection or 2 in a lag on one switch. Same with enabling and disabling snooping on vlan with single link or lag. The fact that it is still being blocked without a lag and on only one switch makes me believe it isn't a hashing issue. The switches are stacked with 2 10g ethernet ports and the multicast traffic is very minimal, so that shouldn't be the issue.
Hi jdarow32
Thank you, OK you are at Layer 3 for Multicast so definitely sounds like a configuration issue, as PIM still needs to rely on IGMP somehow and there is conflict with other Layer 2 settings most likely.
It's going to be too fastidious in such Community forum to ask questions, back and forth. Better to ask you for your Tech-Support file from your stack when you see the problem occuring. To export the Tech-Support file, you can use the Web GUI and go to Maintenance / Export / HTTP File Export / and select Tech-Support in the dropdown menu. Please send me your contact details by Private Message here, I'll give you my email address and from there you will be able to send me your Tech-Support file and I'll open a case for you.
When your issue will be fixed, we'll sure update the thread here, and if possible describe your use case and indicate the needed config for it.
