Configuring the system network

Last Updated : Nov 15, 2024 |

About this task

This procedure shows example default entries and variables as <variable>. The actual information you enter must match your network setup.

Note:

This procedure describes how to configure the system network using IPv4. To configure IPv6 support, see the chapter Installing and configuring optional software in Maintaining and Troubleshooting Avaya Call Management System.

Procedure

  1. Log on to Linux as a root user.
    Important:

    You cannot directly log on as root from a remote connection. You must log on using an administered CMS user ID, then use su - root to log on with root privileges.

  2. Enter the following command:

    /cms/toolsbin/netconfig

    The system displays the following prompt:

    
     WARNING: This tool only supports IPv4
    
     Enter the network interface name from following name(s): eth0 eth1 eth2 eth3 (default <ethX>)
    
    ENTER>
  3. Accept the default value eth0 and press Enter.

    The system displays the following prompt:

     You have entered [ eth0 ]. Is this correct? (y|n)
  4. Enter y, then press Enter.

    The system displays the following prompt:

    Enter the host name of the CMS system (default <cms_hostname>)
    
    ENTER>
    
  5. Enter the host name of the CMS server and press Enter.

    Hostname for the CMS server

    Important:

    The CMS backup process automatically assigns time-stamped file names that truncate the CMS server hostname if it is longer than 15 characters. To avoid confusion between the backup files for multiple CMS servers, do not use the same first 15 characters for a hostname when you have multiple CMS servers in your deployment.

    The system displays the following prompt:

    You have entered [ <cms_hostname> ]. Is this correct? (y|n)
  6. If you have entered the correct host name, enter y, then press Enter.

    The system displays the following prompt:

    Enter the domain name of the CMS system (default <cms.domain.com>)
    
    ENTER>
  7. Enter the domain name of the CMS server and press Enter.

    The system displays the following prompt:

    You have entered [ <cms.domain.com> ]. Is this correct? (y|n)
  8. If you have entered the correct domain name, enter y, then press Enter.

    The system displays the following prompt:

    Enter the IP address of the network interface (default <IP_address>)
    
    ENTER>
    
  9. Enter the IP address of the CMS server network interface and press Enter.

    The system displays the following prompt:

    You have entered [ <IP_address> ]. Is this correct? (y|n)
    
  10. If you entered the correct IP address, enter y, then press Enter.

    The system displays the following prompt:

    Enter the netmask for the subnet of the network interface (default <netmask_IP>)
    
    ENTER>
    
  11. Enter the netmask for the subnet of the CMS server network interface and press Enter.

    The system displays the following prompt:

    You have entered [ <netmask_IP> ]. Is this correct? (y|n)
  12. If you entered the correct IP address, enter y, then press Enter.

    The system displays the following prompt:

    Enter the gateway of the CMS system (default <Gateway_IP>)
    
    ENTER>
    
  13. Enter the gateway for the CMS server network interface and press Enter.

    The system displays the following prompt:

    You have entered [ <Gateway_IP> ]. Is this correct? (y|n)
  14. If you entered the correct default gateway, enter y, then press Enter.

    The system displays the following prompt:

    Enter the DNS server(s) seperated by space (up to three servers) (default <Maximum_Three_DNS_Servers_IP>) 
    
    ENTER>
  15. Enter the DNS servers of the CMS server and press Enter.

    The system displays the following prompt:

    You have entered [ <Maximum_Three_DNS_Servers_IP> ]. Is this correct? (y|n)
  16. If you entered the correct DNS server(s), enter y, then press Enter.

    The system displays the following prompt:

    Enter the search domains separated by space (default <Search_Domains>, "" for none)
    
    ENTER>
  17. Enter the search domain(s) of the CMS server and press Enter.

    The system displays the following prompt:

    You have entered [ <Search_Domains> ]. Is this correct? (y|n)
  18. If you entered the correct search domains, enter y, then press Enter.

    The system displays the network configuration options you have entered, for example:

    Interface: eth0
    CMS Hostname: cmshostname
    Domainname: tmp.domain.com
    CMS IP address: 10.10.10.10
    Netmask: 255.255.255.0
    Gateway: 10.20.30.40
    DNS Server1: 40.30.20.10
    DNS Server2: 100.200.300.400
    DNS Server3:
    Search domains: tmp.domain1.com tmp.domain2.com
    
    Are the above inputs correct? (y|n)
    
  19. Perform one of the following actions:
    • If any of the network configuration entries are not correct, enter n, then press Enter.

      The network configuration process returns to step 3.

    • If the network configuration entries are correct, enter y, then press Enter.

      The system attempts to bring up the network and if successful, displays a successfully finished message.

      Bring the network up. Please wait... 
      
      <timestamp> /cms/toolsbin/netconfig successfully finished
  20. If the network configuration was not successful, troubleshoot the network for outages and repeat this procedure. If the network configuration fails again, escalate through normal channels. Test your network settings to ensure that the network settings are working properly using the following commands:

    ifconfig <ethX> (use your actual Ethernet port)

    ping <system on your local network>

    Press Control+C to exit the ping command.

    Note:

    If the network does not respond, enter ifup <ethX>. If the network still does not respond, repeat this procedure and verify that the values entered are correct.
