Hi,
there is a server with 2 or 4 interfaces grouped in teaming, connected to 6500 switch ports in etherchannel, using trunk with 2 VLANs allowed (eg. 20 & 40)
On the other port a PC connected to access port in one of these VLANs sees a lo of the unicast traffic sourced from and destined to the server connected to etherchannel ports.
How can it be controlled?
Regards,
k

Hello Kpandric,
if the server is sending traffic to a destination MAC address that is not speaking the switches flood the frames on every port on that vlan (unicast flooding)
you should check if the destination MAC address(es) of server traffic are in the CAM table or not.
Hope to help

Hi giuslar,
good point, in ARP table I see
6509#show arp | inc f091
Internet 10.10.240.145 122 02bf.0a0a.f091 ARPA Vlan240
however, there is similar but not exactly the same MAC address on the etherchannel interface:
6509#sh mac-address-table | inc f091
* 240 0202.0a0a.f091 dynamic Yes 0 Po1
* 240 0201.0a0a.f091 dynamic Yes 0 Po1
thanks
