9.14.2 BMC Network Bonding
Bonding feature provides a method for aggregating multiple network interfaces into a single
logical bonded network interface. Although multiple network interfaces are bonded, only
one is available at a time. In run-time, the netif_carrier (network link state) is monitored by
polling periodically.
l
Bonding function is disabled by default, users can enable it in Web GUI or IPMI CMD.
l
Only support Active-backup bonding mode. Default bonding on both NICs (Dedicated and
Shared NICs), means network will be working on the NIC plugged with cable. If both NICs
plugged with cable before BMC bootup, shared NIC will be primary network to be working.
If one NIC plugged with cable before BMC bootup, then anther plugged later, the first NIC
will be working.
l
After bonding, bonding interface uses shared NIC’s MAC to access network, including
bonding to dedicated or shared NIC.
9.14.3 NCSI
NC-SI (Network Controller Sideband Interface) is an electrical interface and protocol defined
by the Distributed Management Task Force (DMTF), which enables the connection of a
Baseboard Management Controller (BMC) to a set of Network Interface Controllers (NIC) in
server computer systems for the purpose of enabling out-of-band remote manageability.
It mainly includes: a management controller (MC), one or more (support up to 4 NCSI
electrical characteristics) network controllers (NC). The network controller, on the one hand,
connects the external network interface to the internal host interface, and on the other
hand, there is an out-of-band interface between the management controllers.
The network management module structure of the server is shown as below.
