The TN3270 PU Table is contained in the MIB module for objects used to manage the TN3270 server and is accessed by clicking an Index hyperlink in the TN3270 Global screen.
The PU table contains objects that describe the PU configuration parameters not defined in the NAU MIB, APPN MIB or DLUR MIB. The Global Table contains general information about the state of the server, while the PU table goes one level down to look at the devices per card attached to the server.
The fields on the TN3270 PU Table are:
Index |
Index used to uniquely identify each Node instance. This is the same as snaNodeAdminIndex in the NAU MIB. Click the Index hyperlink to access the TN3270 LU Table. |
Address |
The IP address of this TN3270 server. |
TCP Port |
The TCP port of this TN3270 server Telnet session. |
Idle Timeout |
The number of seconds of LU inactivity, from either host or client, before the TN3270 session is disconnected. Zero seconds means that LU sessions, by default, are not disconnected when inactive, regardless of the amount of idle time spent. 65535 (not valid in server context) indicates that the idletime value should be taken from the server context. |
Keep Alive |
The number of seconds of inactivity from the client side that the TN3270 Server allows to elapse before sending DO-TIMING-MARK to the TN3270 client. If the client does not reply within thirty minutes of such a TIMING-MARK sending, the server disconnects the TN3270 session. Zero seconds indicates that no keepalives will be sent. 65535 (not valid in server context) indicates that the default keepalive value for an LU is taken from whatever value had been defined in the server context for this CIP card. |
On UnBind |
The On Unbind variable indicates whether or not a TN3270 session will be disconnected upon UNBIND. Keep indicates that no automatic disconnect will be made by the server upon receipt of an UNBIND. Disconnect indicates that the session will be disconnected upon receipt of an UNBIND. Inherit indicates that the default keepalive value of a LU is taken from whatever value had been defined in the server context for this CIP card. |
Generic Pool |
The Generic Pool variable indicates whether or not leftover LUs will be made available to TN3270 sessions, which do not request a specific LU or LU pool. A “leftover” LU is defined as one for which both of the following conditions hold true: the SSCP did not send an ACTLU during PU startup, and the PU controlling the LU is capable of carrying PSID vectors on NMVT messages (thus allowing DDDLU operation for that LU). |
State |
The Status value identifies the current PU state. This has a different meaning for direct and DLUR PU before the link station is established. For DLUR PU, the PU is in reset state, for direct PU, this will be either sending a TEST or an XID. |
Type |
Type defines whether the connection to the host is via DLUR or direct link. LuSend, LMAC/SAP, and RMAC/SAP in this table are undefined if the connection to the host is via DLUR. |
PU-LU Send |
For Direct PU this defines the LU name prefix (LU seed), which is concatenated with the localddr to form a unique name. |
Local SAP Address |
SAP address of the local direct node. |
Remote SAP Address |
SAP address of the remote node. Valid for direct PU only. |
