Broadcom virtual adapter - intergrated with two port on two different 6509

[sandeepatel]

I hv integrated two NIC through Virtual broadcam adapter(software) to two different cisco 6509 ports. Both cisco is interconnected and STP has been enable and working fine.

Server NIC MAC 1 - a.a.a.a

Server NIC MAC 2 - b.b.b.b

Virtual IP for broadcom - 10.10.10.10

Vlan : 60

Cisco 6509 -1 port : 7/2 ( nic a.a.a.a)

Cisco 6509 - 2 port : 7/4 ( nic b.b.b.b)

Issue I am facing is when I am viewing the CAM table enteries below is the result

Cisco 6509 - 1 Cam table

Mac a.a.a.a - port 7/2

Mac b.b.b.b - Port 1/1 (interconnected

port between

6509 switches )

Cisco 6509 - 2 Cam table

Mac a.a.a.a - port 1/1 (interconnected

port between

6509 switches)

Mac b.b.b.b - Port 7/4

But suprisingly seeing the ARP table I see two different MAC on the network for same IP

i.e

Cisco 6509-1 - 10.10.10.10 - a.a.a.a vlan60

Cisco 6509-2 - 10.10.10.10 - b.b.b.b vlan 60

This seems to be created some problem in the same vlan60.

How to resolve such issue with virtual server loadbalancing ?

Those Broadcoms (or any other standard server nics for that matter i believe) will not load balance across seperate switches. The teaming software is designed for either redundancy (if a switch goes down it will default to the other) or mainly for double the speed - and you have to plug them into the same switch and enable etherchannel. Right now you are seeing what the switches should be expecting from the server software.

Thanks Robert,

curious on that ,

How I can configure the perferct method to configure server load balancing with teaming NIC on the system side and also Network load balancing on the Network side.

so i don't only hv the SLB but also NLB with high high redundancy.
