Configuring an M2M service

To configure an M2M service:

  1. Navigate to the topology in one of the following ways:
  2. Click the M2M service that you want to configure.

    The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon expand_panel_up_icon_2.

  3. In the Name field, enter the name of the M2M service.
  4. If necessary, in the Description field, enter a brief description of the M2M service.
  5. In the Connection points field, enter the maximum number of M2M service connection points. Range of values: 2 to 9999. If you do not specify a value for this setting, the number of connection points is unlimited.
  6. In the MAC age (sec.) field, enter the time period in seconds during which entries are kept in the MAC table of the controller. Range of values: 10 to 65,535. Default value: 300.
  7. In the MAC learn mode drop-down list, select the action that you want to apply to a series of frames when the first frame is sent to the controller to learn the source MAC address:
    • Learn and flood means the controller remembers the MAC address of the source and checks for the presence of the destination MAC address in the MAC table. If the destination MAC address is not in the MAC table, the series of frames is sent to all service interfaces added to the P2M service, except for the service interface on which the series of frames originally arrived. Default value.
    • Learn and drop means the controller remembers the MAC address of the source and checks for the presence of the destination MAC address in the MAC table. If the destination MAC address is not in the MAC table, the series of frames is dropped.

    If the destination MAC address is present in the MAC table, the series of frames is sent to the destination service interface.

  8. In the MAC table size field, enter the maximum number of entries in the MAC table on the controller. Range of values: 0 to 65,535. 0 means the number of entries is not limited. Default value: 100.
  9. In the MAC table overload drop-down list, select the policy for processing new MAC addresses when the MAC table of the controller is full:
    • Flood means traffic with destination MAC addresses that have not been learned is transmitted as BUM traffic (Broadcast, unknown-unicast, and multicast). Default value.
    • Drop means that traffic with destination MAC addresses that have not been learned is dropped.
  10. If you want to configure the assignment of IP address to virtual network functions using DHCP:
    1. In the OpenStack DHCP drop-down list, select Enabled. The default value is Disable.
    2. In the CIDR field, enter the IPv4 prefix of the OpenStack subnet that assigns IP addresses to virtual network functions.
    3. If you want the OpenStack subnet to assign a particular gateway to virtual network functions, enter the IPv4 address of the gateway in the Gateway field.
    4. Specify the range of IP addresses from which the OpenStack subnet assigns IP addresses to virtual network functions: To do so, under Pools, click + Pooland enter the starting and ending values of the IP address range.

      The range of IP addresses is specified and displayed in the Pools section. You can specify multiple IP address ranges or delete an IP address range. To delete an IP address range, click Delete next to it.

    5. Specify the DNS server that the OpenStack subnet assigns to virtual network functions. To do so, under DNS, click + DNS and enter the IPv4 address of the DNS server.

      The DNS server is specified and displayed in the DNS section. You can specify multiple DNS servers or delete a DNS server. To delete a DNS server, click Delete next to it.

  11. If you want to use an M2M service to create a shared network service, select the Share network service check box. This check box is cleared by default.
  12. In the upper part of the settings area, click Save to save M2M service settings.
