Configuring Network-Related Settings

Network Management in Cisco BMC 2.0

Cisco BMC 2.0 offers diverse interfaces, including Web GUI, Redfish, and IPMI commands, to facilitate comprehensive management of the BMC network. Network configuration involves tasks such as configuring IP addresses, IP address sources, and gateways.

Fundamental network configuration features include:

  • IP Addresses Source

  • IP Address

  • Gateways

  • subnet mask

Note

The Shared NIC (eth1) is associated with the X710 OCP card. Ensure this configuration is considered when setting up your network interfaces to optimize connectivity and performance.

When using OCP (eth1) for management traffic, the NCSI support is available only on Port 1 of the OCP card.

Procedure

Step 1

From the Navigation Pane, click Administration > Networking.

Step 2

Select the Networking Settings tab.

Step 3

Under Network Settings, update the following properties:

Name

Description

Hostname field

Click the edit button to update the domain name.

Use domain name toggle button

Enable or disable the option to use the domain name for network communications.

Use DNS servers toggle button

Enable or disable the option to use DNS servers for resolving hostnames to IP addresses.

Use NTP servers toggle button

Enable or disable the option to use Network Time Protocol servers to synchronize the BMC's clock.

Use Shared NIC (eth1) toggle button

Enable or disable the option to use the shared network interface card (NIC) eth1 for network connectivity.

Step 4

Under eth0/eht1, you can view the following properties:

Name

Description

Link status field

Indicates the current status of the network link, showing whether it is active (LinkUp) or inactive.

Speed (mbps) field

Displays the current speed of the network connection in megabits per second (Mbps).

FQDN field

Specifies the fully qualified domain name (FQDN) assigned to the interface.

MAC address field

Displays the unique Media Access Control (MAC) address assigned to the network interface.

Step 5

See Viewing or Adding IPv4 Address to update the IPv4 addresses and Viewing or Adding IPv6 Address to update the IPv6 addresses.

Step 6

Click Save Settings.

Viewing or Adding IPv4 Address

Procedure

Step 1

From the Navigation Pane, click Administration > Networking.

Step 2

Select the Networking Settings tab.

Step 3

Under IPv4, update the following properties:

Name

Description
Current address origin

Specifies the current IPv4 address setting.

DHCP radio button

Allows you to select Dynamic Host Configuration Protocol (DHCP) for automatic IP address assignment.

Static radio button

Allows you to select Static IP configuration, which requires you to manually enter the IP address, gateway, and subnet mask details.

When you enable Static, the fields are enabled.

IP Address field

Specify the Internet Protocol (IP) address assigned to the device, which uniquely identifies it on the network.

Gateway field

Enter the IP address of the network gateway, which serves as the access point or router that passes traffic between the local network and other networks or the internet.

Subnet mask field

Enter the network address range by specifying which portion of the IP address refers to the network and which part refers to the device.

Viewing or Adding IPv6 Address

Procedure

Step 1

From the Navigation Pane, click Administration > Networking.

Step 2

Select the Networking Settings tab.

Step 3

Under IPv6, update the following properties:

Name

Description

Current address origin

Specifies the current IPv6 address setting.

DHCPv6/SLAAC radio button

Allows you to enable automatic IPv6 address configuration through Dynamic Host Configuration Protocol or Stateless Address Autoconfiguration.

Static radio button

Allows you to select Static IP configuration, which requires you to manually enter the IP address and Prefix length details.

When you enable Static, the fields are enabled.

IP Address field

Specify the Internet Protocol (IP) address assigned to the device, which uniquely identifies it on the network.

Prefix length field

Specify the prefix length to define the network portion of the IPv6 address, which determines the size of the subnet.

IPv6 default gateway field

Click the edit icon to open the dialog box and enter the IPv6 address of the default gateway for routing traffic outside the local network.

Link local address field

Displays the automatically assigned link-local IPv6 address used for communication within the local network segment; not editable.

SLAAC address field

Shows the automatically configured SLAAC IPv6 address, assigned for autonomous device communication; not editable.

Viewing, Adding, or Deleting Static DNS IP Address

Procedure

Step 1

From the Navigation Pane, click Administration > Networking.

Step 2

Select the Networking Settings tab.

Step 3

Under Static DNS, click Add IP address.

Add IP address window is displayed.

Step 4

In the Add IP address window, update the following properties:

Name

Description

Static DNS field

Enter the static DNS server addresses to be used for domain name resolution when DHCP is disabled.

Step 5

Click Add.

Viewing, Adding, or Deleting Domain Name

Before you begin


Note

You can specify up to one domain name servers only.

Procedure

Step 1

From the Navigation Pane, click Administration > Networking.

Step 2

Select the Networking Settings tab.

Step 3

Under Domain name, click Add.

Add Domain address window is displayed.

Step 4

In the Add Domain window, update the following properties:

Name

Description

Domain Name field

Enter the domain name that identifies your network or resource for proper addressing and access.

Step 5

Click Add.

Step 6

(Optional) To delete a domain name, click the delete icon corresponding to the row you want to delete.

Network Time Protocol Settings

By default, when Cisco BMC 2.0 is reset, it synchronizes the time with the host. With the NTP service, you can configure Cisco BMC 2.0 to synchronize the time with an NTP server. The NTP server does not run in Cisco BMC 2.0 by default. You must enable and configure the NTP service by specifying the IP/DNS address of at least one server or a maximum of four servers that function as NTP servers or time source servers. When you enable the NTP service, Cisco BMC 2.0 synchronizes the time with the configured NTP server. The NTP service can be modified only through Cisco BMC 2.0.


Note

To enable the NTP service, it is preferable to specify the IP address of a server rather than the DNS address.

Configuring Network Time Protocol Settings


Note

Configuring NTP disables the IPMI Set SEL time command.

Procedure

Step 1

From the Navigation Pane, click Administration > Networking.

Step 2

Select the NTP Settings tab.

Step 3

In the Configure settings area, choose between the following options:

  • Manual

  • NTP

Step 4

For Manual, update the following properties:

Name

Description

Date YYYY-MM-DD field

Enter in YYYY-MM-DD format.

Enter time in HH:MM format.

Step 5

For NTP, update the following properties:

Name

Description

Server 1 field

Specify the first NTP server.

Server 2 field
