Network Configuration (CLI)

Modifying the network configuration setting in a restricted Colocation environment can be far easier to achieve via the command line. The first step is SSH into the system, change to the specified directory and view the current network settings, as shown below.

Specifically:

interface name

Hardware Port

Description

man0

L1 1G RJ45

1G management port

bmc

IPMI 1G RJ45

1G Out of bands management port

man10

SFP/QSFP 10G/40G

High speed management port

Default Settings

Interface Name

IP Address

Netmask

Gateway

DNS

man0

192.168.0.95

255.255.255.0

192.168.0.1

192.168.0.1

bmc

192.168.0.93

255.255.255.0

192.168.0.1

man10

192.168.15.95

255.255.255.0

Example configuration is shown below

fmadio@fmadio10-049:/mnt/store0/etc$ cat network.lua
local Config =
{
["man0"] =
{
    ["Mode"]    = "static",
    ["Address"] = "192.168.0.95",
    ["Netmask"] = "255.255.255.0",
    ["Gateway"] = "192.168.0.1",
    ["DNS"]     = "192.168.0.1",
},
["man10"] =
{
    ["Mode"]    = "static",
    ["Address"] = "192.168.15.95",
    ["Netmask"] = "255.255.255.0",
    ["Gateway"] = "",
    ["DNS"]     = "",
},
["bmc"] =
{
    ["Mode"]    = "static",
    ["Address"] = "192.168.0.93",
    ["Netmask"] = "255.255.255.0",
    ["Gateway"] = "",
    ["DNS"]     = "",
},
}
return Config

After editing the file, save it and confirm no syntax errors, running the following command

A successful output looks like the following

Reboot the system and confirm the IP settings are correct

Management VLAN

There may be a requirement for management VLAN interfaces on the FMADIO packet capture system. These are simple to add using the standard linux infrastructure

Example is to create a VLAN 123 on the 10G man10 interface. Add the following configuration to

Create a new entry names "man10.123" as follows

The only difference is the addition of the "vlan" setting and an entry named "man10.123" all other fields are configured as a normal static interface.

After configuring be sure to run the following to confirm the configuration file is formatted correctly. The following is the correct output

Changing BMC/IPMI Network Settings

In addition to the above, if the BMC information has been changed, please run the following command to configure BMC IP address on the system.

Example output of BMC IP configuration is shown below

Once Complete confirming the BMC IP network settings using the following command

Example output looks like the following

After confirming the IP address, BMC IP address is pingable also reachable with IPMITOOL, HTTP and HTTPS.
