NEC ESMPRO Manager Ver.5 Installation Guide (Linux)

2.4.1 Notes on Managed Components and Network Devices

This section explains particular notes on managed components and network devices.

-- Use of network switch / router

If the managed component installed BMC that uses a standard LAN port or loaded Advanced Remote

Management Card, and there is network switch / router between manager server and the managed

components, please set the network switch / router to receive Gratuitous ARP.

See each instruction manual of the switch / router about how to set it.

-- 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 component is connected.

Set “Enable” for the auto-negotiation function of the port to which a managed component is connected.

-- Use of DHCP

In case that BMC on the managed component 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 Manager server in which the NEC ESMPRO

Manager is to be installed.

To use a managed component in a DHCP environment, start NEC DianaScope Agent or NEC ESMPRO

Agent Extension.

-- Setting of Teaming for standard LAN with the OS (providing redundancy or multiplexing with multiple

network adapters) for the managed component installed BMC that uses a standard LAN port:

The managed component 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 component is available, do not set

LAN2 in

the BMC configuration information.

- Even if the configuration of LAN2 for the BMC on the managed component is available, do not set

LAN2 in

the BMC configuration information.

- If the teaming is set with channel bonding on Linux, please add “mode” and “primary” definition to the

line of /etc/modprobe.conf or /etc/modules.conf as following.

-- Setting of Teaming for LAN with the OS (providing redundancy or multiplexing with multiple network

adapters) for the managed component installed BMC that uses a Management LAN port:

If the teaming setting was made available for the LAN port that NEC DianaScope Agent or NEC

ESMPRO Agent Extension uses, see “Appendix C. Managed Components Summary” of the “NEC

ESMPRO Manager Ver.5 Setup Guide”.
