3.4 Notes on managed servers and network devices
This section explains particular notes on managed servers and network devices.
 Use of network switch / router
If the managed server installed BMC that uses a standard LAN port or loaded Advanced Remote Management
Card, and there is network switch / router between management PC and the managed servers, set the network
switch / router to receive Gratuitous ARP. See each document of the switch / router about how to set it.
If Gratuitous ARP cannot be received, managed server that is power-off status is not connected.
 Use of a layer-2 / layer-3 switching hub
Set "Disable" for the STP (Spanning Tree Protocol) function of the switching hub or the STP of the port to which a
managed server is connected.
Set "Enable" for the auto-negotiation function of the port to which a managed server is connected.
 Use of DHCP
In case that BMC on the managed server uses a standard LAN port, communication between the NEC ESMPRO
Manager and System BIOS or BMC is not compatible with a DHCP environment.
Be sure to use a fixed IP address with the NEC ESMPRO server in which the NEC ESMPRO Manager is to be
installed.
To use a managed server in a DHCP environment, start the DianaScope Agent or NEC ESMPRO Agent Extension.
 Setting of Teaming for standard LAN with the OS (providing redundancy or multiplexing with multiple
network adapters) on the managed server installed BMC that uses a standard LAN port
The managed server installed BMC that uses a standard LAN port shares the embedded standard LAN controller
between BMC, System BIOS and OS, but the BMC and System BIOS do not support the LAN teaming modes
including AFT (Adapter Fault Tolerance) and ALB (Adaptive Load Balancing). So if the AFT mode or ALB mode
was made available by OS, NEC ESMPRO Manager can communicate with BMC and System BIOS only under the
following conditions while Failover does not occur.
- If RLB (Receive Load Balancing) is set with ALB (Adaptive Load Balancing), disable the RLB. (If RLB
cannot be disabled, NEC ESMPRO Manager cannot communicate with BMC.)
- Make the Teaming-set address ("preferred primary") identical to the LAN1 IP address and MAC address in
the BMC configuration information.
- Even if the configuration of LAN2 for the BMC on the managed server is available, do not set LAN2 in the
BMC configuration information.
- See "Appendix B B.1 On the managed server that BMC uses standard LAN port" in "NEC ESMPRO
Manager Ver.5 Setup Guide" if you install DianaScope Agent or NEC ESMPRO Agent Extension on the
managed server whose operating system is Windows.
Note that NEC ESMPRO Manager cannot communicate with BMC when you use RLB (Receive Load
Balancing) or FEC (Fast Ether Channel) teaming mode on the managed server.
