Hello,

Walking past a switch today I noticed all the lights blinking at a very high rate. We where not doing any Ghost multicasts, so there should not be that many broadcasts in our network.
Wireshark quickly showed VMWARE Mac addresses sending a huge amount of LLC messages.

Our network is very simple, one subnet, no VLAN's etc

Google and search of VMTN only returned a lot of post from people working at LLC's :)

1) Is it normal to see that many LLC messages
2) what is their function
3) can I do anything to reduce it

Tx!

Could you tell us a bit more about you environment? Like How many ESX servers and how are they wired? With Virtual Center? How many VMs and their operating systems?
