Network Interfaces

Select MM Control → Network Interfaces to configure network access.

The following illustration shows the Network Interfaces page for an advanced management module.

Attention: Once IPv6 has been enabled, disabling it or updating advanced management module firmware to a level that does not support IPv6 addressing causes all IPv6 connectivity to be lost. Services and interfaces that are configured for IPv6 operation might not function properly and you will need to reconfigure these services and interfaces.

Select Network Interfaces to configure the management-module Ethernet interfaces. For the advanced management module, you can configure only the external Ethernet interface that is used to communicate with the remote management and console. The internal Ethernet interface for the advanced management module has no user-configurable settings.

The advanced management module supports both IPv4 and IPv6 addressing. IPv4 addressing is always enabled and IPv6 is enabled by default. In the External Network Interface (eth0) section, if the IPv6 Enabled checkbox is not selected, IPv6 addressing is disabled for the BladeCenter unit and you will see an additional checkbox to suppress display of IPv6 information. You must click Save for any changes to take effect. The status of the internal (eth1) Ethernet connection for the primary management module is Enabled and cannot be changed.

Note: If IPv6 is enabled, at least one of the IPv6 configuration methods (IPv6 static, DHCPv6, or stateless auto-configuration) must also be enabled and configured.

For I/O-module communication with a remote management station, through the management-module external Ethernet port, the I/O-module internal network interface and the management-module internal and external interfaces must be on the same subnet.

The Primary Management Module section displays information about the interface for the primary management-module remote management and console port.

Note: If your BladeCenter unit supports redundant management modules and you plan to use this feature with both management modules set to use the same external IP address, disable DHCP and DHCPv6 and configure and use a static IP address. This action must be performed for both IPv4 and IPv6, as appropriate. (The IP configuration information is transferred to the standby management module automatically when it is needed.)

The Advanced Failover section sets how the management module behaves when it switches over to the standby management module during failover. It also displays information about the interface for the standby management-module remote management and console port, similar to the External Network Interface (eth0) section and Primary Management Module section for the primary management module.
