To request a list of TCP/IP data for all physical interfaces, use format
IFCD0100. For detailed information about Filter and IPSec physical interface
data in addition to the IFCD0100 format data, use format IFCD0200.
The physical interface description list consists of:
- A user area
- A generic header
- An input parameter section
- A header section
- A list data section:
- IFCD0100 format.
- IFCD0200 format.
- IFCD0300 format
For details about the user area and generic header, see User Space Format for List APIs. For details about the remaining
items, see the following sections.
When you retrieve list entry information from a user space, you must use the
entry size returned in the generic header. The size of each entry may be padded
at the end. If you do not use the entry size, the result may not be valid. For
examples of how to process lists, see API Examples.

Line description. 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).
Note: As of V5R2,
IP over IPX is no longer supported.
|
| *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). |
| *TNLCFG64 |
This special value means this line description is
a Configured 6-4 (IPv6 over IPv4) tunneling line. IPv6 Neighbor Discovery does
not work over a Configured tunnel, so you don't get the benefit of stateless
autoconfiguration.
 Note:
As of V5R4, this value is no longer supported.
|
Line type. Type of line used by an interface. The following
link protocols are supported:
| -1 |
OTHER -

to not perform Duplicate Address Detection. |
Hop limit - configured. The configured IPv6 Hop Limit value
specified for this physical interface. The Hop limit field is the IPv6
replacement for the IPv4 Time to live (TTL) field. The Hop limit value
specifies a relative limit on the number of hops across which an IPv6 datagram
remains active. The Hop limit value is hop count that is decremented by each
gateway to prevent internet routing loops. The default Hop limit value is 64.
Valid values range from 1 through 255 hops.
Hop limit - current. The IPv6 Hop Limit value currently in
effect for this physical interface. The Hop Limit field is the IPv6 replacement
for the IPv4 Time to live (TTL) field. The Hop Limit value specifies a relative
limit on the number of hops across which an IPv6 datagram remains active. The
Hop Limit value is hop count that is decremented by each gateway to prevent
internet routing loops. The default Hop Limit value is 64. If the current Hop
Limit value differs from the configured Hop Limit value, then it has been set
by a Hop Limit value received in a Router Advertisement packet. Valid values
range from 1 through 255 hops.
IPv6 interface identifier. A 64-bit number which is
combined with prefixes to create complete IPv6 addresses for the physical
interface. By default it is based on the link layer (MAC) address, if one
exists. The interface identifier is represented here in standard IPv6 address
format notation. It does not include a leading "::" for the first 64 bits of a
full IPv6 address, and it may include an embedded IPv4 address at the end. This
field is NULL padded.
IPv6 interface identifier binary. Binary representation of
the IPv6 interface identifier.
Local tunnel endpoint IPv4 address. The IPv4 address of the
local tunnel endpoint of this tunnel, returned in dotted decimal format. This
field is NULL padded.
The following special value may be returned:
| 0.0.0.0 |
This physical interface is not a tunnel, so this
field does not apply.
Note:
As of V5R4, tunneling is not supported. As a result, this field is always set to 0.0.0.0.
|
Local tunnel endpoint IPv4 address binary. Binary
representation of the Local tunnel endpoint IPv4 address.
The following special value may be returned:
| 0 |
This physical interface is not a tunnel
Note:
As of V5R4, tunneling is not supported. As a result, this field is always set to 0.
|
MTU - configured. The configured maximum transmission unit
(MTU) value specified for this physical interface.
The following is a special value:
| 0 |
LIND - The MTU was configured as *LIND, the MTU
value from the line description. |
MTU - current. Maximum transmission unit (MTU) value
currently in effect for this physical interface.
The following is a special value:
| 0 |
LIND - The interface is not active currently and
the MTU was configured as *LIND. |
Neighbor discovery base reachable time - configured. The
configured Neighbor Discovery (ND) Base Reachable Time value, in seconds,
specified for this physical interface. The ND Base Reachable Time value is a
base time value used for computing the random ND Reachable Time value. The
default ND Base Reachable Time is 30 seconds. Valid values range from 10
through 100 seconds.
Note:
As of V5R4, this field is always set to 30.
Neighbor discovery base reachable time - current. The
Neighbor Discovery (ND) Base Reachable Time value, in seconds, currently in
effect for this physical interface. The ND Base Reachable Time value is a base
time value used for computing the random ND Reachable Time value. The default
ND Base Reachable Time is 30 seconds. If the current ND Base Reachable Time
value differs from the configured value, then it has been set by a ND Base
Reachable Time value received in a Router Advertisement packet. Valid values
range from 10 through 100 seconds.
Note:
As of V5R4, this field is always set to 30.
Neighbor discovery reachable time. The current Neighbor
Discovery (ND) Reachable Time value, in seconds, for this physical interface.
The ND Reachable Time value is the amount of time, in seconds, that a neighbor
is considered reachable after receiving a reachability confirmation. The ND
Reachable Time value is randomly calculated, using the ND Base Reachable Time
and a couple constants. This calculation is performed to prevent Neighbor
Unreachability Detection (NUD) messages from synchronizing with each other.
Note:
As of V5R4, this field is always set to 0.
Neighbor solicitation retransmit interval - configured. The
configured Neighbor Solicitation (NS) Retransmit Interval value, in seconds,
specified for this physical interface. The NS Retransmit Interval is the time,
in seconds, between retransmissions of Neighbor Solicitation messages to a
neighbor when resolving the link-layer address, or when probing the
reachability of a neighbor. The default NS retransmit interval is 1 second.
Valid values range from 1 through 10 seconds.
Note:
As of V5R4, this field is always set to 1.
Neighbor solicitation retransmit interval - current. The
Neighbor Solicitation (NS) Retransmit Interval value currently in effect for
this physical interface. The NS Retransmit Interval is the time, in seconds,
between retransmissions of Neighbor Solicitation messages to a neighbor when
resolving the link-layer address, or when probing the reachability of a
neighbor. The default NS Retransmit Interval is 1 second. If the current NS
Retransmit Interval value differs from the configured value, then it has been
set by a NS Retransmit Interval value received in a Router Advertisement
packet. Valid values range from 1 through 10 seconds.
Note:
As of V5R4, this field is always set to 1.
Packet rules - IPv6. Indicates what kind of IPv6 packet
rules are loaded on a particular line.
Possible values are:
| -1 |
Other - An unknown Packet rules value. |
| 0 |
None - No NAT and no filters are loaded for the
line specified. |
| 1 |
NAT - NAT is enabled for this line. |
| 2 |
Filters - Filters are defined for this line. |
| 3 |
NAT and Filters - NAT enabled and Filters defined
for this line. |
| 4 |
Filters and IPSec - Filters and IPSec filters are
defined for this line. |
| 5 |
NAT and Filters and IPSec - NAT enabled and
Filters and IPSec filters defined for this line. |
Reserved. An ignored field.
Text description. User
added text description associated with the physical interface.
Text description CCSID. Coded character set ID for the text description.
Total inbound IPv6 packets discarded. The number of inbound
IPv6 packets which were chosen to be discarded even though no errors had been
detected to prevent their being deliverable to a higher-layer protocol. One
possible reason for discarding such a packet could be to free up buffer
space.
Total IPv6 anycast packets received. The number of IPv6
anycast packets delivered to a higher-layer protocol.
Total IPv6 anycast packets sent. The number of IPv6 anycast
packets that higher-level protocols requested be transmitted, including those
that were discarded.
Total IPv6 bytes received. The total number of IPv6 bytes
received on the interface, including framing characters.
Total IPv6 bytes sent. The total number of IPv6 bytes
transmitted out of the interface, including framing characters.
Total IPv6 multicast packets received. The number of IPv6
multicast packets delivered to a higher-layer protocol.
Total IPv6 multicast packets sent. The number of IPv6
multcast packets that higher-level protocols requested be transmitted,
including those that were discarded.
Total IPv6 unicast packets received. The number of IPv6
unicast packets delivered to a higher-layer protocol.
Total IPv6 unicast packets sent. The number of IPv6 unicast
packets that higher-level protocols requested be transmitted, including those
that were discarded.
Total outbound IPv6 packets discarded. The number of
outbound IPv6 packets which were chosen to be discarded even though no errors
had been detected to prevent their being transmitted. One possible reason for
discarding such a packet could be to free up buffer space.
Use other stateful configuration. Whether the TCP/IPv6
stack has been informed by a Router Advertisement to use non-address stateful
(that is, DHCPv6) configuration information that it receives on this physical
interface.
Possible values are:
| -1 |
UNKNOWN - The system has not received any Router
Advertisements on this physical interface. |
| 0 |
NO - The system has been informed to not use any
non-address stateful configuration information that it receives on this
physical interface. |
| 1 |
YES - The system has been informed to use any
non-address stateful configuration information that it receives on this
physical interface. |
Note:
As of V5R4, this field is always set to 0.
Use stateful address configuration. Whether the TCP/IPv6
stack has been informed by a Router Advertisement to use stateful (that is, DHCPv6)
configuration information that it receives on this physical interface for the
purpose of address autoconfiguration.
Possible values are:
| -1 |
UNKNOWN - The system has not received any Router
Advertisements on this physical interface. |
| 0 |
NO - The system has been informed to not use
stateful configuration information that it receives on this physical interface
for the purpose of address autoconfiguration. |
| 1 |
YES - The system has been informed to use
stateful configuration information that it receives on this physical interface
for the purpose of address autoconfiguration. |
Note:
As of V5R4, this field is always set to 0.
Use stateless autoconfig. Whether the TCP/IPv6 stack
performs stateless autoconfiguration on this physical interface or not.
Possible values are:
| 0 |
NO - The system will not perform the stateless
autoconfig algorithms on this physical interface. |
| 1 |
YES - The system will perform the stateless
autoconfig algorithms on this physical interface. |
