I'll keep this short as there isn't a lot to it.
I have an ESX cluster (8 servers) connected to a 8024f. There are 2 vlans that the ESX cluster operates on, I am able to connect to both of them from my desktop. The switch has a very basic config, mostly trunk all ports to ESX and 4 ports ether-channeled to the core Cisco. I have been tasked with getting MS NLB multicast working, but I've had a %$&& of a time doing it. For the most part I've enabled multicast but I'm not having any luck so I went further to also enable IGMP ... then I made it a querier. At the end of the day I didn't get anywhere except one screen (MFDB IGMP Snooping table) that seems to tell me that on my one VLAN there are 2 dynamic "Network Assist" mac address for two different ports (labeled under "Table" and those same mac addresses are listed under "Forbidden ports"
What am I doing wrong? Funny thing is this was working (I admit with a lot less of a config before today) a week ago until one of the VMware engineers tweaked with an interface
Update- I wrote all this yesterday but it seems that it was never posted. Sense then I decided to remove all the commands from the switch that I entered in for this and start from scratch. I will be creating a port on the switch and assigning my laptop to it. If I can connect to the cluster then I’ll know that the problem is at the core Cisco switch… and I’ll be asking that question here as well. I made no special changes to the core when connecting this switch for multicast, considering the core is already running multicast I didn’t think I had to
