dual NIC bonding on Server cause MAC flapping

Publication Date:  2014-12-30 Views:  782 Downloads:  0
Issue Description
The server NIC cards working in the bond mode. They work in load balance. The NIC1 connect to port G0/0/1 in S5700-1 and NIC2 connect to port G0/0/01 in S5700-2. The two switches connect by cable both by port g0/0/2. S5700-1 and S5700-2 configure VRRP, S5700-1 is the master, and S5700-2 is the backup. The service was break when the issue coming.
Solution
Try to configure the working mode of the bond NIC to master and slave mode, there will only one NIC send the data. There is no MAC flapping happen.
Try to configure 2 NIC to the same switch. And configure the eth-trunk on the two port in switch, to make the load balance on switch.

The NIC in server configure bond mode. If the bond card working in load balance mode, two switches will both receive the package which send to server, and create the MAC table.
