Help for IP Resource Interface Selection

This help page explains the display of all of the interfaces defined to the TCP/IP resource. There is a hierarchical relationship between various interfaces on a given host. This hierarchical relationship is represented by indenting the Interface Number on the MVS Stack Interface Selection page to show that an interface is subordinate to the previous interface. See RFC2233 for more details.

Interface List for

This is the interface list for the IP address displayed.

Select

Select a radio button corresponding to the interface listed. After selecting a radio button a user can view details and possibly connections for the corresponding interface.

Interface Number

A unique value, greater than zero, for each interface. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant, at least from one re-initialization of the entity's network management system to the next re-initialization.

Desired Status

The desired state of the interface. The value of the desired state can be active, down, or test. The testing state indicates that no operational packets can be passed. When a managed system initializes, all interfaces start with ifAdminStatus in the down state. As a result of either explicit management action or per configuration information retained by the managed system, ifAdminStatus may then change to active or test. Click on the drop-down list to select another status.

Actual Status

The current operational state of the interface. The testing state indicates that no operational packets can be passed. If ifAdminStatus is down, then ifOperStatus should also be down. If ifAdminStatus is changed to active, then ifOperStatus should also change to active if the interface is ready to transmit and receive network traffic. It should change to dormant if the interface is waiting for external actions (such as a serial line waiting for an incoming connection). It should remain in the down state if there is a fault that prevents it from changing to active. It should remain in the not present state if the interface has missing components (typically, hardware). Click on the drop-down list to select another status. This value can be one of the following:
  • Active
  • The interface is up and ready to pass packets.
  • Down
  • The interface is down.
  • Test
  • The interface is in some test mode.
  • Unknown
  • The interface status cannot be determined.
  • Dormant
  • The interface is dormant.
  • Not Present
  • A component for the interface is missing.
  • Lower Level Down
  • The interface is down due to state of a lower-layer interface or interfaces.

    IP Address

    The IP address to which this entry's addressing information pertains.

    Description

    A textual string containing information about the interface. This string should include the name of the manufacturer, the product name, and the version of the interface hardware/software.

    View Details

    Click on the View Details button to display the detail information about the interface corresponding to the selected radio button. The interface number corresponding to the selected radio button will be displayed on the View Details button.

    View Connections

    Click on the View Connections button to list all connections for the interface corresponding to the selected radio button. The IP address corresponding to the selected radio button will be displayed on the View Connections button. If the interface does not have an associated IP address, the button will be inactive and state No IP Address for this Interface.
