Summary of Contents for Cisco 11.0 BT

  • Page 1 Cisco IOS Release 11.0(10)BT and later. Note that Cisco IOS Release 11.0(10)BT is the initial release of Cisco IOS Release 11.0 BT. No prior versions of Cisco IOS Release 11.0 BT exist. The TN3270 server function is supported on a Channel Interface Processor card in a Cisco 7000 series or Cisco 7500 series router.

  • Page 5 • SNA Functions From the perspective of an SNA 3270 host connected to the CIP, the TN3270 server is an SNA device that supports multiple physical units (PUs), with each PU supporting up to 255 logical units (LUs). The LU can be Type 1, 2, or 3. The SNA host is unaware of the existence of the TCP/IP extension on the implementation of these LUs.
  • Page 6 LU group to find an LU template. The model type is a four character string; the model number is a two or three character string. The server will accept the following formats of terminal type string from the client: •...
  • Page 7 LU names from the ACTLUs. For direct PUs, a “seed” name can be configured on the PU. The TN3270 server uses this name in conjunction with the LOCADDRS to generate names for the LUs. It is best to use the same naming convention as the host, if possible.
  • Page 8 171.69.176.43 is allocated an LU from that PU and is routed to that host. Note that by using the DLUR function, all the LUs in the server can be defined and owned by a controlling VTAM. When a client requests an application residing on a different VTAM host, the controlling VTAM will issue the request to the target host which will send a BIND directly to the client.
  • Page 9 NMVT with a “Reply Product Set ID” control vector. After the TN3270 server sends a positive response to the ACTPU, it will wait for VTAM to send ACTLUs for all specifically defined LUs. In the sample configuration shown in Figure 2, ACTLUs will be sent for TN3X1100 and TN3X1101.
  • Page 10 TN3270 Configuration Modes The TN3270 configuration modes and router command prompts are described in the following sections and displayed in Figure 3. The TN3270 server can be configured only on Port 2, the internal LAN port, of a CIP card.

  • Page 12 PU Configuration Mode There are two paths to PU configuration mode: from the TN3270 server configuration mode, or from the DLUR configuration mode. In either mode, the pu command puts you in PU configuration mode. From TN3270 configuration mode, the pu command to create a new PU is:...
  • Page 13 The following sections describe how to configure TN3270 server support on the CIP. Not all tasks are required. Refer to “TN3270 Configuration Example” for configuration examples. The TN3270 server is configured on an internal LAN interface in the CIP, which is port 2 of Note a CIP.

    This update describes the commands to configure TN3270 support on the Channel Interface Processor (CIP). For TN3270 configuration tasks and examples, refer to the “Configuring TN3270 Server on the Channel Interface Processor” update chapter of this Release Note. The following commands are documented in this update chapter: •...
  • Page 20: Dlur

    Cisco IOS software. Fully qualified name of the primary choice for the dependent LU server (DLUS). This is the name of an LU, usually a CP, in an APPN host. The fq-dlusname value can be repeated and shared across servers.
  • Page 21: Dlus-Backup

    NETID and is shared between entities in the same logical network. Example The following command specifies SYD.VMX as the backup DLUS: dlus-backup SYD.VMX Fully qualified name of the backup DLUS for the DLUR. dlus-backup TN3270 Server Commands...
  • Page 22: Generic-Pool

    All LUs in the generic pool are, by definition, DDDLU capable. Values entered for generic-pool in TN3270 configuration mode apply to all PUs for that TN3270 server but can be changed in PU configuration mode. In PU configuration mode, a no generic-pool command will restore the generic-pool value entered in TN3270 command mode.
  • Page 23 Similarly, if generic-pool permit is specified, any inactive LUs are immediately available for dynamic connections. Moreover, any active LUs that were dynamic previously (before generic-pool deny was issued) return to being dynamic. Example The following command permits generic LU pool use: generic-pool permit TN3270 Server Commands...
  • Page 24: Idle-Time

    Usage Guidelines The idle-time command can be entered in either TN3270 configuration mode or PU configuration mode. A value entered in TN3270 mode applies to all PUs for that TN3270 server, except as overridden by values entered in PU configuration mode.
  • Page 25: Keepalive

    The keepalive command can be entered in either TN3270 configuration mode or PU configuration mode. A value entered in TN3270 mode applies to all PUs for that TN3270 server, except as overridden by values entered in PU configuration mode. A no keepalive command entered in PU configuration mode will restore the keepalive value entered in TN3270 command mode.
  • Page 26: Link

    For a link via a channel on this CIP, the TN3270 server and the hosts should open different adapters in the same internal LAN. Using different adapters avoids any contention for SAP numbers, and is also necessary if you configure duplicate MAC addresses for fallback CSNA access to the host.
  • Page 27 The following example shows different adapter numbers configured on the same internal LAN to avoid SAP contention. The host uses SAP 4 on token ring adapter 0: lan tokenring 0 adapter 0 4000.0000.0001 adapter 1 4000.0000.0002 tn3270-server dlur ... lsap token-adapter 1 link HOST rmac 4000.0000.0001 rsap 4 link TN3270 Server Commands...
  • Page 28: Lsap

    The no lsap command hierarchically deletes any links using it. Any sessions using those links are lost. TN3270 Server Commands Internal adapter type on the CIP card, which corresponds to the value specified in the lan internal LAN configuration command.
  • Page 29 Example The following command defines an adapter type, an adapter number, and a local SAP: lsap token 0 B0 Related Commands adapter TN3270 Server Commands...
  • Page 30: Maximum-Lus

    Use the maximum-lus TN3270 configuration command to limit the number of LU control blocks that will be allocated for TN3270 server use. Use the no form of this command to restore the default value. maximum-lus number no maximum-lus...
  • Page 31: Preferred-Nnserver

    If refused, it will try the next one, and so on. If a preferred server is specified, then DLUR will wait a short time to allow a link to the preferred server to materialize. If the preferred server is not found in that time, any suitable node can be used, as above.
  • Page 32: Pu (Direct)

    802.2 clients of that adapter, in the router or in a host, should be allocated the same SAP. Other direct links from TN3270 server direct PUs may use the same value on the internal adapter as long as the remote MAC or SAP is different.
  • Page 33 CIP internal LAN interface are used in the pu command. For a link via a channel on this CIP, the TN3270 server and the hosts should open different adapters in the same internal LAN. Using different adapters avoids any contention for SAP numbers, and is also necessary if you configure duplicate MAC addresses for fallback CSNA access to the host.
  • Page 34 (direct) Related Commands adapter TN3270 Server Commands...
  • Page 35: Pu (Dlur)

    The value must be unique within the domain; however, the TN3270 server generally cannot tell which remote hosts are in which domains, so the server only enforces uniqueness within the set of DLUR PUs. IP address that the clients should use as host IP address to map to LU sessions under this PU.
