The AKN_INTERFACE application class provides information for the TCP/IP interfaces defined on the system.
Application class attributes
InfoBox
The following information is displayed on the AKN_INTERFACE InfoBox:
| |
---|
Associated local interface | The internet address, in dotted decimal notation, of the local interface that has been associated with this interface. The value *NONE indicates that no association has been made between this interface and another local interface. |
| Indicates the internet address of the interface. |
| Each TCP/IP interface is associated with a physical network. This field displays the name of the communications line description that identifies the physical network associated with an interface. The following special values may also be displayed: - *IPI - This interface is used by Internet Protocol (IP) over Internetwork Packet Exchange (IPX). A specific physical line is not associated with an interface used by IP over IPX (IPI).
- *IPS - The interface is used by Internet Protocol (IP) over SNA. A specific physical line is not associated with an interface used by IP over SNA (IPS).
- *LOOPBACK - The interface is a loopback interface. Processing associated with a loopback interface does not extend to a physical line. There is no line description associated with a loopback address.
- *VIRTUALIP - The virtual interface is a circuitless interface. It is used in conjunction with the associated local interface (LCLIFC) when adding standard interfaces. This special value is used to accommodate any of the following cases:
- Load balancing. This is the means of having a fixed source IP address regardless of which interface the traffic is being distributed.
- Frame-relay multi-access network to define the local network IP address. This allows for multiple virtual circuits to share the same IP network.
- Alternate method of network access translation (NAT). This eliminates the need for a NAT box by assigning a globally unique single IP address directly to the box without the need to define an entire network.
- Unnumbered networks. This provides a means of associating a local source IP address for an unnumbered point-to-point network.
- *OPC—This special value is used if you are adding an OptiConnect interface over TCP/IP. This interface is attached to the optical bus (OptiConnect).
|
| The value in this field indicates the type of physical line used by an interface. The following link protocols are supported: - *ASYNC - Asynchronous communications protocol.
- *DDI - Distributed Data Interface protocol.
- *ELAN - Ethernet local area network protocol.
- *FR - Frame relay network protocol.
- *PPP - Point-to-Point Protocol.
- *TRLAN - Token-ring local area network protocol.
- *WLS - Wireless local area network protocol.
- *X25 - X.25 protocol.
- *TDLC - Twinaxial Datalink Control. Used for TCP/IP over Twinax.
The following special values can also be displayed: - *ERROR - This value is displayed if any system errors other than those for *NOTFND are received while trying to determine the link type for an interface.
- *IPI - Internet Protocol (IP) over Internetwork Packet Exchange (IPX). The specific line type that is used by an IP over IPX (IPI) interface cannot be determined.
- *IPS - Internet Protocol (IP) over SNA. The specific line type that is used by an IP over SNA (IPS) interface cannot be determined.
- *NONE - Line not defined. This is used for the *LOOPBACK, *VIRTUALIP, *OPC interfaces. There is no line type value for these interfaces.
- *NOTFND - Not found. This value is displayed if the line description object for this interface cannot be found.
|
| Indicates the internet address of the IP network or subnetwork to which the interface is attached. |
| Indicates the physical address of the interface. |
| The current status of the logical interface. |
| Indicates the subnet mask identifying the part of the network where this interface attaches. |
| Indicates the type of service used for internet quality selection. Setting the TOS is intended to improve service.The following special values are used to indicate the TOS: - *NORMAL - used for delivery of datagrams.
- *MINDELAY - used for prompt delivery of datagrams with the minimize delay indication.
- *MAXTHRPUT - used with high data rate of datagrams with the maximize throughput indication.
- *MAXRL - used for a higher level of effort to ensure delivery of datagrams with the maximize reliability indication.
- *MINCOST - used as a lower cost delivery method of datagrams with the minimize monetary cost indication.
- *IPI - used as an Internet Protocol (IP) over Internetwork Packet Exchange (IPX) route. The TOS value is not used for an IP over IPX (IPI) interface or route.
- *IPS - used as an Internet Protocol (IP) over an SNA interface or route. The TOS value is not used for an IP over an SNA (IPS) interface or route.
