Configuring the management-module Ethernet port

You can use the web interface to configure the management-module external Ethernet port and the internal Ethernet management port on each I/O module.

Note: Do not configure the blade server and the AMM to be on the same IP subnet. The AMM should be on an IP subnet dedicated to management traffic.

To configure the management-module external Ethernet port, complete the following steps:

Under MM Control in the navigation pane, click Network Interfaces.
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.
In the External Network Interface (eth0) section, enable or disable IPv6 addressing using the IPv6 Enabled checkbox. IPv4 addressing is always enabled and IPv6 is enabled by default. If IPv6 addressing is disabled for the BladeCenter unit, you will see an additional checkbox to suppress display of IPv6 information. You must click Save for any changes to take effect.
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.
Configure the IPv4 and IPv6 external Ethernet interface (eth0) in the Primary Management Module section.
Note: For I/O-module communication with a remote management station, such as a management server that is running IBM® Systems Director server, 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.
1. The following configuration settings apply to both IPv4 and IPv6 addressing:
  - Hostname field: (Optional) This is the IP host name that you want to use for the management module (maximum of 63 characters and following host-naming standards).
  - Domain name field: The domain name of the management module that is used in conjunction with a dynamic domain name server (DDNS).
  - Register this interface with DNS checkbox: If checked, the configured DNS servers (see Network Protocols) will also be considered DDNS servers and domain name information will be sent to them.
2. The following configuration settings apply to IPv4 addressing:
  - DHCP: Select one of the following choices:
    - Enabled: Obtain IP config. from DHCP server
    - Disabled: Use static IP configuration
    - Try DHCP server. If it fails, use static IP config. (the default; DHCP times out after 2 minutes)
    Note: If the management-module DHCP setting is set to Try DHCP server. If it fails, use static IP config., the management module uses the static IP address when the DHCP server is not available during management-module startup. When this occurs, the IP address might not be reachable if multiple management modules were started with the same static IP address.
  - IPv4 Static IP configuration: Configure this information only if DHCP is disabled.
    - IP address: The IPv4 IP address of the management module must contain four integers from 0 through 255, separated by periods, with no spaces or consecutive periods. The default setting is 192.168.70.125.
    - Subnet mask: The subnet mask must contain four integers from 0 to 255, separated by periods, with no spaces. The default setting is 255.255.255.0
    - Gateway address: The IP address of your network gateway router must contain four integers from 0 through 255, separated by periods, with no spaces. This address must be accessible from the IP address and subnet mask that were specified above.
  - Click IP Configuration Assigned by DHCP Server to view the IP configuration that was assigned by the DHCP server. (This choice is available only when DHCP is enabled.)
3. The following configuration settings apply to IPv6 addressing. They will only be seen if IPv6 is enabled or if IPv6 is disabled and display of IPv6 settings has not been suppressed.
  Note: For IPv6, both DHCPv6 and IPv6 static configuration can be enabled at the same time, each with their own address. Hosts like the advanced management module can have multiple IPv6 addresses.
  - Link-local address: (read only) A unique IPv6 address for the advanced management module that is automatically generated based on the MAC address.
  - IPv6 Static IP configuration: IPv6 static IP configuration is disabled by default.
    Note: The advanced management module will not have a fixed static IPv6 address by default. For initial access, users can use either the default IPv4 address or the IPv6 link-local address.
    - IP address: The IPv6 IP address of the management module must be 16 hexadecimal bytes, divided along 2-byte boundaries, delimited with colons, of the form: 2001:0DB8:0000:0000:02AA:00FF:FE28:9C5A
    - Address prefix length (1-128): The prefix length for the IPv6 address. The address prefix length is not configurable for the standby advanced management module: the same value as the primary advanced management module is used.
    - Default route: The IP address of your network gateway router must be 16 hexadecimal bytes, divided along 2-byte boundaries, delimited with colons, of the form: 2001:0DB8:0000:0000:02AA:00FF:FE28:9C5A. The default route is not configurable for the standby advanced management module: the same value as the primary advanced management module is used.
  - DHCPv6: Select one of the following choices:
    - Enabled: Obtain IP configuration from DHCP server (the default)
    - Disabled: Not obtain IP configuration from DHCP server
  - Stateless Auto-configuration: Automatic configuration of addresses is based on the receipt of Router Advertisement messages. These messages include stateless address prefixes. Stateless auto-configuration is enabled by default.
Configure the internal Ethernet management port on each I/O module in the BladeCenter® unit.
Note:
- Some types of I/O modules, such as a pass-thru module, have no management port.
- Some I/O modules do not support IPv6 addressing.
1. Under I/O Module Tasks in the navigation pane, click Configuration.
2. Click Bay 1.
3. In the New Static IP address fields, specify the IP configuration to use for this interface. For IPv4, the subnet mask must be the same as the subnet mask in the internal network interface (eth1).
4. Click Advanced Configuration.
5. In the Advanced Setup section, enable external management over all ports.
6. Under I/O Module Tasks in the navigation pane, click Admin/Power/Restart.
7. In the I/O Module Advanced Setup section, select I/O module 1; then, enable the external ports. (External ports have a default value of Disabled.)
Note: The initial user ID and password for the I/O module firmware are as follows:
- User ID: USERID (all capital letters)
- Password: PASSW0RD (note the zero, not O, in PASSW0RD)
Repeat step 3 for each I/O module in the BladeCenter unit.

To communicate with the blade servers for functions such as deploying an operating system or application program, you also must configure at least one external (in-band) port on an Ethernet I/O module.
