Description:
When diagnosing backup failures to NDMP attached tape drives we can see various connection down messages that usually relate to response timeouts between filer and netvault server or client.
This can be caused by VIF (Virtual network interfaces) were the VIF configuration has multiple NIC's (Teaming) in it and these are connected to intelligent switch. As it is not really our a netvault problem to make sure the configuration rules on the filer and switches are implemented correctly. So on occasions need to be able to exclude the VIF teamed configuration and below is explains a way of doing this.
