3.4 Notes on managed servers and network devices
This section e xplains 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 l oaded Advanced Remote Manage
ment Card, a nd there is ne twork switch / router be tween manager se rver and the managed servers, set t
he network switch / rou ter to receive Gratuitous ARP. See each document of the switch / router about ho
w to set it.
If Gratuitous ARP cannot be received, managed server that is po wer-off status is not con nected.
 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 t
o which a m anaged server is connected.
Set "Enable" for the a uto-negotiation function of t he port to which a m anaged server is con nected.
 Use of DHCP
In case that BMC on the managed server uses a standard LAN port, communica tion between the NEC E
SMPRO Manager and System BIOS or BMC is not c ompatible with a DHCP environment.
Be sure to use a fixed IP address with the NEC ESMPRO server in which the NEC ESMPRO Manager i
s to be i nstalled.
To use a managed server in a DHCP environment, start the D ianaScope Agent or NEC E SMPRO Agent
Extension
 Setting of Teaming for standard LAN with the OS (providing redundancy or multiplexing with multip
le network adapters) on the managed server installed BMC that uses a standard LAN port
The managed server inst alled BMC that uses a standard LAN port shares the embedded st andard LAN c
ontroller between BMC, S ystem BIOS and OS, but th e BMC and S ystem BIOS do not support the LAN t
eaming modes including AFT (Adapter F ault Tolerance) and ALB (Adaptive Load Balancing). So if the AFT
mode or ALB mode was made available by OS, N EC ESMPRO Manager can communicate with BMC an
d System BIOS onl y 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.
