TN3270 LU Table (subscreen of TN3270 PU Table)

The TN3270 LU table provides information on each LU associated with the selected PU in the PU Table. The TN3270 LU table is accessed by clicking an Index hyperlink in the TN3270 PU Table.

The LU Table has two subtables:

·         Traffic/Status

·         APPN

Figure 89. TN3270 LU Table

 

Use the Back and Next buttons on the screen to open a TN3270 LU Table for the previous or for the next OID listed in the Index column of the TN3270 PU Table.

For example, if you clicked Index hyperlink 2 in the TN3270 PU Table screen to get to the current screen, click Back to go to Index hyperlink 1 or Next to go to Index

hyperlink 3.

The fields on the LU Table screen are:

Index

Index used to uniquely identify each LU associated with the selected PU. (or . . . "each node instance?"

Address

SLU Name

The name of the secondary LU.

TCP Port

The TCP port of the client for this LU Telnet session.

Telnet Type

The Telnet Type indicates whether the negotiated TN3270 session is TN3270, TN3270E or never connected.

Term Model

Terminal type or model number of the incoming TN3270 client.

Type

Indicates whether the LU is dynamic or static:

(1) Dynamic. LU is configured as DDDLU.

(2) Static. LU is configured as specific. The host sends an ACTLU as soon as the PU is active.

 

TRAFFIC/
STATUS subtable

 

Address

State

Current LU state of the client:

 

Inactive

LU didn't receive ACTLU.

 

Active

LU received ACTLU and acknowledged positively.

 

PSdt

LU is bound but there is no SDT yet.

 

act/session

LU is bound and in session.

 

PActlu

Telnet connects in and is awaiting ACTLU.

 

PNotifyAve

pNotifyUa

Awaiting host notify-unavailable response.

 

pReset

Waiting for a buffer to send DACTLU response.

 

pPsid

pUnbind

Awaiting host unbind response.

 

UnbindWt

Waiting client acknowledgement of disconnect.

 

SdtWt

Awaiting client's acknowledgement of an SDT.

Current Inbound Pacing

The number of inbound frames allowed to be sent to the host without receiving a pacing response from the host.

Current Inbound Queue Size

After the inbound pacing credit is exhausted, the inbound data is queued. This is the number of inbound frames queued waiting for a host pacing response.

Current Outbound Queue Size

The number of TCP packets in the server queued for transmission to the client.

Idle Time

Time since last activity was recorded on this LU.

APPN subtable

 

Address

The IP address of the TN3270 client connected to this LU.

APPN Link Index

Only valid for DLUR LU. The link index into an APPN MIB for the link on which the bind flowed.

LFSID

Session identifier on a PU 2.1 link.

Events

An array of octets indicating the latest events that happened in this LU. Octet 1 is the most recent event, octet 2 is the next most recent event, and so on. Although the maximum number of events kept is 16, the actual number of events kept may be lower than that value. When more events are generated than can be kept, the oldest ones are discarded. Events are:

 

1 Inactivity timer expired

2 Dynamic timer expired

3 ACTLU from host

4 Bind from host

5 Clear from host

6 DACTLU from host

7 Hierarchical reset from PU (warn ACTPU)

8 SDT from host

9 Unbind from host

10 Notify response from host

11 Reply psid negative response from host

12 Reply psid pos response from host

13 Unbind response from host

14 Hierarchical reset from PU

15 Connect from client

16 Disconnect from client

17 Timing-mark response from client

18 Flow control timer expired

19 Negative response to host

20 Negative response from host

21 Data contention happened

22 No buffer to send response

23 Receive a SNA response while inbound

LU Nail

Indicates whether this LU has been configured (Nailed) for a specific TN3270 client:

TRUE              LU is nailed to the client IP address.
