Configuring Service-Port Interfaces

Configuring Service-Port Interfaces

Information About Service-Port Interfaces

The service-port interface controls communications through and is statically mapped by the system to the service port.

The service port can obtain an IPv4 address using DHCP, or it can be assigned a static IPv4 address, but a default gateway cannot be assigned to the service-port interface. Static IPv4 routes can be defined through the controller for remote network access to the service port.

Similarly, the service port can be statically assigned an IPv6 address or select an IPv6 address using Stateless Address Auto-Configuration (SLAAC). The default gateway cannot be assigned to the service-port interface. Static IPv6 routes can be defined through the controller for remote network access to the service port.


Note




Note


This is the only SLAAC interface on the controller, all other interfaces must be statically assigned (just like for IPv4).

Restrictions for Configuring Service-Port Interfaces

  • Only Cisco 7500 Series Controllers and Cisco 5500 Series Controllers have a physical service-port interface that is reachable from the external network.

  • You must not use the service-port for continuous SNMP polling and management functions except when the management interface of the controller is unreachable.

Configuring Service-Port Interfaces Using IPv4 (GUI)


    Step 1   Choose Controller > Interfaces to open the Interfaces page.
    Step 2   Click the service-port link to open the Interfaces > Edit page.
    Step 3   Enter the Service-Port Interface parameters:
    Note    The service-port interface uses the controller’s factory-set service-port MAC address.
    • DHCP protocol (enabled)

    • DHCP protocol (disabled) and IP address and IP netmask

    Step 4   Click Save Configuration to save your changes.
    Step 5   If you made any changes to the management or virtual interface, reboot the controller so that your changes take effect.

    Configuring Service-Port Interfaces Using IPv4 (CLI)


      Step 1   To view the current service-port interface settings, enter this command:
      show interface detailed service-port
      Note   

      The service-port interface uses the controller’s factory-set service-port MAC address.

      Step 2   Enter these commands to define the service-port interface:
      • To configure the DHCP server, enter this command:

        config interface dhcp service-port enable

      • To disable the DHCP server, enter this command:

        config interface dhcp service-port disable

      • To configure the IPv4 address, enter this command:

        config interface address service-port ip-addr ip-netmask

      Step 3   The service port is used for out-of-band management of the controller. If the management workstation is in a remote subnet, you may need to add a IPv4 route on the controller in order to manage the controller from that remote workstation. To do so, enter this command:

      config route add network-ip-addr ip-netmask gateway

      Step 4   To remove the IPv4 route on the controller, enter this command:

      config route delete ip_address

      Step 5   Enter the save config command to save your changes.
      Step 6   Enter the show interface detailed service-port command to verify that your changes have been saved.

      Configuring Service-Port Interface Using IPv6 (GUI)


        Step 1   Choose Controller > Interfaces to open the Interfaces page.
        Step 2   Click the service-port link to open the Interfaces > Edit page.
        Step 3   Enter the Service-Port Interface parameters:
        Note    The service-port interface uses the controller’s factory-set service-port MAC address. Service Port can be statically assigned an address or select an address using SLAAC.
        • SLACC(enabled)

        • SLACC (disabled) and Primary Address and Prefix Length

        Step 4   Click Save Configuration to save your changes.
        Step 5   If you made any changes to the management or virtual interface, reboot the controller so that your changes take effect.

        Configuring Service-Port Interfaces Using IPv6 (CLI)


          Step 1   To view the current service-port interface settings, enter this command:
          show interface detailed service-port
          Note   

          The service-port interface uses the controller’s factory-set service-port MAC address.

          Step 2   Enter these commands to define the service-port interface:
          • To configure the service port using SLACC , enter this command:

            config ipv6 interface slacc service-port enable

          • To disable the service port from using SLACC, enter this command:

            config ipv6 interface slacc service-port disable

          • To configure the IPv6 address, enter this command:

            config ipv6 interface address service-port iipv6_address prefix-length

          Step 3   The service port is used for out-of-band management of the controller. If the management workstation is in a remote subnet, you may need to add a route on the controller in order to manage the controller from that remote workstation. To do so, enter this command:

          config ipv6 route add network_ipv6_addr prefix-len ipv6_gw_addr

          Step 4   To remove the IPv6 route on the controller, enter this command:

          config ipv6 route delete network _ipv6 addr

          Step 5   Enter the save config command to save your changes.
          Step 6   Enter the show interface detailed service-port command to verify that your changes have been saved.
