KN3 Interface Status Attributes

Use the KN3 Interface Status attributes to display status information for all interfaces defined to a z/OS(R) v1r12 or later system.

Notes:

This attribute group is available only on systems running z/OS® v1.12 or later.
A blank in any of these fields means that this attribute does not apply to this interface either at all or at this time.

Actual Dynamic Type The actual dynamic inbound performance type. This value is stored as an integer and displayed as a string. Valid values are:

128 = WORKLOADQ_in_effect

The value for this attribute will be non-zero only when the Actual Inbound Performance Type has a value of DYNAMIC.

This value is specified with the INBPERF optional parameter on the LINK statement in the TCPIP.PROFILE dataset. The DYNAMIC setting causes the host to dynamically signal the OSA-Express feature to change the timer-interrupt value, based on current inbound workload conditions. The DYNAMIC setting is effective only for OSA-Express2 features on an IBM® System z9® EC or z9® BC with the corresponding Dynamic LAN Idle functional support. See the IBM z/OS Communications Server IP Configuration Reference for more information.

This value is specified with the INBPERF optional parameter on the LINK statement in the TCPIP.PROFILE dataset and indicates how frequently the OSA adapter should interrupt the host for inbound traffic. See the IBM z/OS Communications Server IP Configuration Reference for more information. The name of this attribute is abbreviated Actual Perf Type in the enhanced 3270 interface.

Actual MTU Value The actual maximum transmission unit (MTU) value. The format is a 2-byte unsigned integer.

Maximum transmission unit (MTU), or maximum packet size in TCP/IP terms is the maximum size for the data field. For a static route, the MTU size for a route is configured using the on either a ROUTE statement in a BEGINROUTES block or on a GATEWAY statement in the TCP/IP profile. For each IPv4 dynamic route added by OMPROUTE over an interface, the configured route MTU comes from the value of the MTU keyword specified on the RIP_INTERFACE, OSPF_INTERFACE or INTERFACE statement in the TCPIP.PROFILE dataset for that interface in the OMPROUTE configuration file. If you do not specify an MTU for an interface, OMPROUTE uses 576. For IPv6, OMPROUTE learns the interface MTU value from TCP/IP, and you cannot specify a configured route MTU in the OMPROUTE configuration file. The name of this attribute is abbreviated Act MTU in the enhanced 3270 interface.

System ID The SMF system ID. The format is a string up to 4 characters in length.

Sysplex Name The name of the Sysplex that this LPAR is a member of. The format is a string up to 8 characters in length.

TCP Segmentation Offload Active Indicates whether the TCP segmentation offload function is active for this interface. This value is stored as an integer and displayed as a string. Valid values are:

0 = No
1 = Yes

The TCP/IP stack can offload most IPv4 outbound TCP segmentation processing to an OSA-Express feature in queued direct input/output (QDIO) mode using TCP segmentation offload support. You can configure this function by specifying the SEGMENTATIONOFFLOAD parameter on the GLOBALCONFIG profile statement. See the IBM z/OS Communications Server IP Configuration Guide for more information about this parameter. The name of this attribute is abbreviated TCP Seg Offload in the enhanced 3270 interface.

TCPIP STC Name The TCP/IP job name. The format is a string up to 8 characters in length.

Temporary IP Address Prefix Indicates whether the temporary IP address prefix is being specified for this interface. This value is stored as an integer and displayed as a string. Valid values are:

0 = No
1 = Yes

This value is specified with the ADDTEMPPREFIX parameter of the IPAQENET6 interface statement. This prefix represents the number of unmasked leading bits in the ipaddress value. The prefix length value can be in the range 0 - 127 for IPv6 addresses. An IP packet matches this condition if its unmasked bits are identical to the unmasked bits defined. See the IBM z/OS Communications Server IP Configuration Reference for more information about this parameter. The name of this attribute is abbreviated Temp IP Address Prefix in the enhanced 3270 interface.

Temporary Prefix Type The temporary prefix type. This value is stored as an integer and displayed as a string. Valid values are:

1 = ALL
2 = Prefix_specified
3 = NONE
4 = Disabled_DAD_failures

VLAN ID The virtual LAN (VLAN) identifier. The format is a 2-byte unsigned integer.

The VLAN ID is an optional parameter followed by a decimal number indicating the Virtual LAN identifier to be assigned to the OSA-Express INTERFACE. See the IBM z/OS Communications Server IP Configuration Reference for more information.

VLAN ID Specified Indicates whether a virtual LAN (VLAN) identifier is specified for this interface. This value is stored as an integer and displayed as a string. Valid values are:

0 = No
1 = Yes

VLAN Priority Tagging Active Indicates whether the virtual LAN (VLAN) priority tagging function is active for this interface. This value is stored as an integer and displayed as a string. Valid values are:

0 = No
1 = Yes

VLAN priority tagging extends the capabilities of priority queuing beyond the server to include LAN bridges and switches, providing a way to manage consistent QoS traffic prioritization and service differentiation end-to-end, across switched LAN and WAN networks. See the IBM z/OS Communications Server IP Configuration Guide and the IBM System z9 and zSeries Open Systems Adapter-Express Customer's Guide and Reference for more information about this attribute. The name of this attribute is abbreviated VLAN Priority Tag Active in the enhanced 3270 interface.

VMAC Active Indicates whether the Virtual MAC (VMAC) address function is ACTIVE for this interface. This value is stored as an integer and displayed as a string. Valid values are:

0 = No
1 = Yes

VMAC is a parameter on the INTERFACE statement. VMAC specifies the virtual MAC address, which can be represented by 12 hexadecimal characters. The OSA-Express device uses this address rather than the physical MAC address of the device for all IPv4 packets sent to and received from this TCP/IP stack. See the IBM z/OS Communications Server IP Configuration Reference for more information about this parameter.

VMAC Address Specified Indicates whether the Virtual MAC (VMAC) address is specified for this interface. This value is stored as an integer and displayed as a string. Valid values are:

0 = No
1 = Yes

VMAC ROUTELCL Active Indicates whether the ROUTELCL parameter (meaning route only packets that come from registered IP addresses to the VMAC) is active in the Virtual MAC (VMAC) address definition for this interface. This value is stored as an integer and displayed as a string. Valid values are:

0 = No
1 = Yes

ROUTELCL is a parameter on the INTERFACE statement. It specifies that only traffic destined for the virtual MAC and whose destination IP address is registered with the OSA-Express device by this TCP/IP stack is forwarded by the OSA-Express. See the router information in the IBM z/OS Communications Server IP Configuration Guide for more information about this parameter.
