Wireless enabled LOM package preset

Use this information to apply preset configuration of wireless enabled LOM package.

Setting up the network topology

A network topology is an arrangement of network in which all nodes connect with each other using network links. Several network topologies presets have been defined to facilitate port assignment of the server. Depends on usage scenario, server can operate as a standalone system or as a cluster with other peer servers.

There are six types of network topology available for chosen (configuration 1-5 are preset, configuration 6 is available for customized).

To change between topologies, use Lenovo XClarity Controller or Embedded Switch CLI (access through SSH):
  • Lenovo XClarity Controller: select topology type in Edge Networking


  • Embedded Switch CLI (access through SSH): use command sudo set_topology 1

    • Change topology by changing the number in the command. Number could be 1-6. Noted that topology 6 could only be used after customized setting had been created.

Note:
  • LTE/WLAN and IPMI over KCS Access are disabled by default, it is required to enable them through XCC.

  • System resets the network settings of ports to default after users change network topology.

Configuration 1:

In configuration 1, most of the ports are used as downlink port (edge port). Server provides maximum capacity of connection for other devices, but without failover protection. LTE and WLAN AP mode are both applicable for usage in this configuration.

Configuration 2:

In configuration 2, port 3 is used as cluster port (inter-switch port). Server provides redundancy, backup, or other usage depends on setting. LTE and WLAN AP mode are both applicable for usage in this configuration.

Configuration 3:

In configuration 3, port 3 and port 4 are used as cluster port (inter-switch port). Server provides its maximum level of cluster toppology (three servers in maximum). LTE and WLAN AP mode are both applicable for usage in this configuration.

Configuration 4:

In configuration 4, port 8 is used as WLAN client port for failover backup. Server connects to the existing Wi-fi as a client, users can access to Lenovo XClarity Controller through Wi-fi rather than physical wired connection. Only WLAN client mode is applicable for usage in this configuration.

Configuration 6 (Custom Configuration):

If no configuration is found to meet the requirements, the customized configuration is available. It is best practice to select a preset which is similar to the requirements, and then adjust the setting through Embedded Switch CLI, see example commands in below:

Table 7. Configuration 6- customized configuration
# Disable DHCP server on Down Link ports
sudo uci set dhcp.lan.dhcpv4=disabled 
sudo uci commit dhcp 
sudo /etc/init.d/dnsmasq restart

# Includes physical ports into Down link 
# Refer to Wired/wireless table in the manual for the detailed interface name
sudo uci set network.edge_lan.ifname='eth1 eth3 eth6'
sudo uci commit network.edge_lan  
sudo /etc/init.d/network restart

# Configure static IP of Down link ports
sudo uci set network.edge_lan.proto=static 
sudo uci set network.edge_lan.ipaddr=192.168.70.254 
sudo uci set network.edge_lan.netmask=255.255.255.0 
sudo uci commit network.edge_lan  
sudo /etc/init.d/network restart

# Save the change into custom preset
sudo save_topology_config

# Change to custom preset (Or go to XCC web,”Edge Networking”, select “custom configuration”)
sudo set_topology 6
Note: To see content of custom configuration, go to Configuration display in Embedded switch CLI for wireless LOM Package configuration.

BMC network bridge

BMC network bridge is an configuration to select the outbound interface to access to BMC management port. There are four options as shown below. The default is “None”, which means only management port can access XCC interface.
