excessive broadcast on E2510-24 switch

Hi,



I have a procurve switch connected to DL380G6 servers which host ESXi on them.



The server has 4 NIC's and two of them are connected directly to the procurve switch for backup and vmotion.



I see excessive broadcase on these ports.



There are two VLAN's set up, please see attached. I am not sure about the setup as someone else did it.



The corporate network people tell me the switch is causing major traffic issues and is bradcasing in muticast, which I don't understand.



Can someone please guide me on what can I do to resolve this. Many thanks

Hi

Have you revise the mode of ports (auto or forced)
I cant see the attached, but I supposed ine VLAN is for Vmotion and the other one is for Backup.

Hello,

not sure about the server side, but maybe you can try to turn on igmp for the vlans.

ProCurve(config)# vlan 10 ip igmp

If there is a lot multicast traffic from servers without igmp support switch handle this traffic as broadcast.
