Configure a static IP address through the CLI

The ExtraHop system is configured by default with DHCP enabled. If your network does not support DHCP, no IP address is acquired, and you must configure a static address manually.

Important:We strongly recommend configuring a unique hostname. If the IP address on the sensor is changed, the console can re-establish connection easily to the sensor by hostname.
  1. Access the CLI through an SSH connection, by connecting a USB keyboard and SVGA monitor to the physical ExtraHop appliance, or through an RS-232 serial (null modem) cable and a terminal emulator program. Set the terminal emulator to 115200 baud with 8 data bits, no parity, 1 stop bit (8N1), and hardware flow control disabled.
  2. At the login prompt, type shell and then press ENTER.
  3. At the password prompt, type default, and then press ENTER.
  4. To configure the static IP address, run the following commands:
    1. Enable privileged commands: 
      enable
    2. At the password prompt, type default, and then press ENTER.
    3. Enter configuration mode: 
      configure
    4. Enter the interface configuration mode: 
      interface
    5. Run the ip command and specify the IP address and DNS settings in the following format: ip ipaddr <ip_address> <netmask> <gateway> <dns_server>
      For example:
      ip ipaddr 10.10.2.14 255.255.0.0 10.10.1.253 10.10.1.254
    6. Leave the interface configuration section: 
      exit
    7. Save the running config file: 
      running_config save
    8. Type y and then press ENTER.
