|---|---|
| Advanced Peer-to-Peer Networking (APPN) | Full APPN Network Node support in Cisco IOS software allows the Cisco router to natively route SNA traffic and provide SNA class of service (COS) for both new (APPC) and legacy (3270) SNA sessions. The APPN feature is an additional option in the IOS software and is available on the Cisco 2500, 3600, 4x00, 7200, and 7x00 routers. |
| Catalyst 1800 Token Ring Switch | Cisco's Catalyst 1800, resulting from the acquisition of Nashoba Networks, is a backbone Token Ring Switch which supports SRB, TB, and SRT as well as SR/TLB to its FDDI up-link. The manageability and filtering capacity of the Catalyst 1800 places it above the market as a choice for high-speed backbone switching in the Token Ring environment. |
| Catalyst 3900 Token Ring Switch | Cisco's Catalyst 3900 is a stackable workgroup Token Ring switch. It supports SRB, SRT, and SRS and can be logically divided into multiple VLANs bridged by an internal bridging function. The Catalyst 3900 also provides copper and fiber Token Ring expansion modules as well as an ATM up-link module. |
| Catalyst 5000 Token Ring Switching Module | Cisco's Catalyst 5000 Token Ring switching module adds Token Ring capability to the popular Cisco 5000 series of switches. It supports SRB, SRT, and SRS and can be logically divided into multiple VLANs bridged by an internal bridging function. A Token Ring LANE function is also available for use with the Catalyst 5000 ATM Line Card (ALC). |
| Catalyst 2600 Token Ring Switch | Cisco's Catalyst 2600, resulting from the collaboration between Kalpana and IBM, is a workgroup Token Ring Switch. It supports SRS which allows existing shared Token Rings to be switched while maintaining one logical ring number. It also supports SRB and ATM up-links. |
| Cisco 7000 Channel Interface Processor (CIP) | Cisco's CIP allows the Cisco 7000, 7010, and 75xx routers to be directly attached to IBM or IBM-compatible mainframes, simplifying network complexity and reducing the total cost of ownership. The CIP supports four different ways of communicating with the mainframe: TCP/IP Datagram, TCP/IP Offload, CSNA, and TN3270 Server. TCP/IP Datagram support comes with the CIP; Offload, CSNA, and TN3270 Server are ordered separately. TCP/IP Datagram and offload are used when TCP/IP is running on the host; CSNA is used when devices talk native SNA to the host. TN3270 Server allows devices to talk TCP/IP to the server and the server to talk SNA to the host. |
| Bisync Tunneling (BSTUN) Feature | Available on the Cisco 2500, 2520, 4000, and 4500 serial interfaces, Bisync Tunneling allows customers to transport branch traffic from automated teller machines (ATMs) and other equipment that uses Bisync protocol over the same links used for SNA and multiprotocol traffic. This feature offers cost savings through consolidation of equipment and communication links in branch locations. |
| Downstream Physical Unit (DSPU) Concentration | A Cisco router can act as a downstream PU concentrator in SNA networks, providing a network access and concentration point for SNA devices to communicate with an upstream mainframe. By reducing the number of PUs that must be defined to VTAM, this feature saves mainframe and NCP resources and reduces bandwidth/restart requirements since VTAM has fewer PUs to activate. |
| Cisco Frame Relay Access Device (CFRAD) | The Cisco CFRAD models 25XXCF provide synchronous and asynchronous ports to connect multiple serial SNA and BSC devices to a frame relay network. The CFRAD can be upgraded to a full router via a software upgrade. CFRADs enable the conversion of branch offices to frame relay without requiring upgrades to the serial devices. |
| Cisco IOS for S/390 | Cisco IOS for S/390 is a TCP/IP stack software product that allows an IBM mainframe to perform as a high-performance server. Cisco IOS for S/390 expands the scope of Cisco IOS technologies to include the mainframe, providing full host-based support of TCP/IP, host and network print services, legacy TN3270 applications, and File Transfer Protocol (FTP) file transfer. |
| Cisco LAN FRAD | The Cisco LAN FRAD models 252xLF are essentially CFRADs with the addition of an Ethernet or token ring port and IP/PX routing. LAN FRADs are targeted at sites that need LAN- and serial-to-Frame Relay branch office solutions. |
| Cisco WebAccess for S/390 | Cisco WebAccess for S/390 is a product family designed to allow users with a Web browser to securely and efficiently access legacy, mainframe-based applications and data. The two initial products in the family are OpenConnect Systems' OC://WebConnect and OpenVista. New WebAccess for S/390 products and enhancements will be produced to allow even more efficient use of network resources, unbeatable end-to-end security, and extension of Cisco IOS technologies from the desktop to the mainframe. |
| QLLC (Qualified Logical Link Control) Conversion | QLLC conversion allows SNA data to traverse an X.25 network without requiring special X.25 software or hardware in SNA devices. This feature improves performance on X.25 backbones, reduces costs, and simplifies consolidation of traditional SNA networks with newer LAN internetworks. |
| Remote Source-Route Bridging (RSRB) | RSRB supports SNA traffic in a LAN environment. It provides encapsulation of SNA, allows routing around link level failure, overcomes source route bridge hop count problems, reduces broadcast messages, eliminates timeouts, and offers a broad selection of media alternatives. |
| Product | Description |
|---|---|
| CiscoWorks Blue Native Service Point (NSP) | Native Service Point enables IBM mainframe operators to monitor, manage, and control Cisco routers from a single NetView or Netmaster console. This protects and leverages the customer's existing investment in both host network management software and personnel trained in managing the network from a mainframe console. With NSP, Cisco provides the customer with the option of managing the routed network from either a mainframe console, CiscoWorks, or both. NSP requires IOS 11.0 and above. |
| CiscoWorks Blue Maps | Maps is a UNIX-based application that runs on a CiscoWorks platform and provides a logical map and problem isolation and determination tools for an RSRB, DLSw+, and/or APPN network. Maps requires IOS 11.0 and above. A Web interface is also provided. |
| CiscoWorks Blue SNA View | SNA View is an add-on CiscoWorks application that requires Maps. SNA View correlates the LUs and PUs that make up the logical SNA network to their physical location in the routed network. In addition, this application allows PUs and LUs to be activated and inactivated from the SNMP workstation. SNA View provides the unique ability to manage both the router and SNA network from an integrated SNMP platform. SNA View requires IOS 11.0 and above in the routers and VTAM 4.1 and above in the mainframe. A Web interface is also provided. |
| CiscoWorks Blue Internetwork Performance Monitor (IPM) | Internetwork Performance Monitor is a UNIX-based application that assists network managers in performance problem isolation by providing hop-by-hop latency information in a network. IPM proactively alerts network managers (via traps and NMVTs) of service levels that are exceeded in the network. IPM requires that a single router in the network be running IOS 11.2 or higher. |
| CSNA Support | Cisco's CIP support for SNA over the channel is called CSNA. With this optional feature, SNA traffic (both 3270 and APPC) is sent to VTAM. CSNA support is seen as an XCA Major Node by VTAM. |
| Data Link Switching Plus (DLSw+) | DLSw is defined by RFC 1795 as the standard method of encapsulating SNA and NetBIOS in TCP/IP. DLSw+ is fully compliant with the standard, plus it provides enhancements for scalability, network availability, and simplified management. DLSw+ supports end devices attached via Token Ring, Ethernet, SDLC, and QLLC. |
| Dependent Logical Unit Requester (DLUR) | DLUR support in IOS allows the router to transport legacy 3270 sessions over an APPN network. DLUR interacts with the Dependent Logical Unit Server on VTAM to establish a path for the existing application traffic. |
| DLSw Lite | DLSw Lite uses RFC 1490 to transport SNA and NetBIOS traffic over frame relay. It supports local acknowledgment without the additional overhead of TCP/IP encapsulation. |
| FRAS (Frame Relay Access Service) | FRAS allows SNA devices to attach directly to an FEP without requiring modification to the end systems, providing a simple, low-cost migration to frame relay. Cisco supports two versions of FRAS: Boundary Network Node (BNN) and Boundary Access Node (BAN). BNN uses the routed format of RFC1490 and requires NCP 7.1 or higher on the FEP. BAN uses the bridged format of RFC1490 and requires NCP 7.3 or higher on the FEP. |
| High Performance Routing (HPR) | HPR is the follow-on to ISR for routing in an APPN network. HPR provides nondisruptive rerouting and reduced overhead in intermediate nodes. HPR has two components: Rapid Transport Protocol (RTP) and Automatic Node Routing (ANR). In the data center, HPR uses Multi-Path Channel (MPC) channel protocol to connect to the mainframe. |
| Intermediate Session Routing (ISR) | ISR is the initial routing algorithm used in APPN. ISR provides node-by-node connection-oriented routing. While ISR supports dynamic rerouting, it does not support nondisruptive rerouting. |
| Native Client Interface Architecture (NCIA) | NCIA is an encapsulation scheme developed by Cisco to encapsulate SNA in TCP/IP at the client workstation. Client software such as Wall Data's RUMBA offer NCIA as a connection option. This allows transparent transport of the SNA data over an IP network. A router near the destination mainframe removes the TCP/IP encapsulation and forwards the SNA data to the host. |

|---|---|
| Polled Async Tunneling | Bank security systems often use Polled Async Tunneling. On the Cisco 2500, 2520, 4000, and 4500 async ports, support for ADT is available in 11.1. Support for the Adplex polled async protocol is available in 11.2. |
| RFC 1490 Support for SNA | In addition to using RFC 1490 for FRAS, Cisco IOS software supports RFC 1490 for direct encapsulation of RSRB, serial tunneling (STUN), or DLSw Lite over frame relay. RFC 1490 uses less overhead than TCP/IP, but does not provide for rerouting around link failures. |
| SDLC (Synchronous Data Link Control) Integration | SDLC can be supported in three different ways: serial tunneling (STUN) of SNA traffic in TCP/IP; SDLC to LLC2 conversion (SDLLC) using RSRB for transport; or DLSw+ which inherently supports media conversion (e.g., SDLC to LLC2 for Ethernet or Token Ring). |
| Source-Route Bridging (SRB) | Source-route bridging is a bridging method that uses the routing information field (RIF) contained within a source-routed packet rather than the destination MAC address to make forwarding decisions. SRB uses the IBM Spanning-Tree Protocol for forwarding of Spanning-Tree Explorer (STE) frames.The Cisco IOS software in the Cisco routers as well as the Catalyst 1800, Catalyst 3900, and Catalyst 5000 Token Ring module support SRB. |
| Source-Route Switching (SRS) | With SRS, frames with and without a RIF are transparently forwarded. In SRS mode, a token ring switch will learn the MAC addresses of devices that are on directly connected rings, but will learn only the route descriptor for devices located on the other side of a source-route bridge, thus reducing the size of the bridge table. The Catalyst 3900 and the Catalyst 5000 Token Ring module support SRS. |
| Source-Route Translational Bridging (SRTLB) | SRTLB allows bridging between a source-route bridged network and a transparently bridged network. SRTLB is supported both in the Catalyst 1800 (TR to FDDI) and the IOS software in the Cisco routers. |
| Source-Route Transparent Bridging (SRT) | SRT is the concurrent operation of source route bridging and transparent bridging on the same interface. Frames with RIFs are source routed; frames without RIFs are transparently bridged. SRT uses the IEEE Spanning-Tree Protocol for both transparent and STE frames. Parallel, load-sharing backbones and duplicate SNA gateway MAC addresses that are supported in a SRB network are not supported by SRT. The Cisco IOS software in the Cisco routers as well as the Catalyst 1800, Catalyst 3900, and Catalyst 5000 Token Ring module support SRT. |
| TCP/IP Datagram | Base software on the CIP card that allows channel access to TCP/IP stacks on a MVS- or VM-based mainframe using the CLAW channel protocol. Both IBM's and Interlink's TCP/IP stacks on the mainframe are supported by the CIP with the TCP/IP Datagram feature. |
| TCP/IP Offload | TCP/IP Offload is supported on Cisco's CIP as an optional feature. It works with IBM's TCP/IP stack on the mainframe offloading the TCP/IP stack onto the CIP and passing data to the applications on the mainframe. |
| TN3270 Server | TN3270 Server is a separately priced application that runs on the CIP. With the TN3270 Server, communication between the client workstation and the CIP is TCP/IP; communication between the CIP and the mainframe is SNA. 100% of the TCP/IP and TN3270 processing cycles are offloaded from the mainframe. TN3270 server is on IOS 11.2. An application, called TN3270 Monitor, is also available to provide management for this service. |
| Token Ring Switch | A Token Ring switch is essentially a multiport bridge that can forward at full media rates. A Token Ring switch can support any or all of the following bridging modes: source-route bridging, source-route switching, transparent bridging, or source-route transparent bridging. |
| Transparent Bridging (TB) | Transparent bridging is a bridging method that uses destination MAC addresses to make forwarding decisions. Transparent bridges will not forward frames that contain a RIF. TB uses the IEEE Spanning-Tree Protocol to prevent loops in the bridged network. The Cisco IOS software in the Cisco routers as well as the Catalyst 1800, Catalyst 3900, and Catalyst 5000 Token Ring module support TB. |
