CHAPTER 2
TN3270 Server Implementation
This chapter discusses the following aspects of TN3270 Server implementation:
• TN3270 Server on the CIP/CPA
• Planning for Implementation
• TN3270 Configuration
• Monitoring the TN3270 Server
TN3270 Server on the CIP/CPA
The TN3270 Server feature of the Cisco IOS software can be used in the following situations:
• When an IP backbone needs to be maintained, but SNA 3270-type clients must be allowed.
With the TN3270 Server in a channel-attached router, SNA can be terminated in the data center and still
support the legacy TN3270 applications. The backbone network outside the data center can be pure IP.
Similarly, if clients in branch offices need TN3270 connectivity, this can be provided without having to support
SNA stacks at the branch office.
• When a TN3270 host TCP/IP stack is being used in conjunction with a TN3270 Server, but mainframe CPU
cycles need to be off loaded.
Enabling the TN3270 Server functions in the router enables you to offload TN3270 and TCP/IP processing
from the host and saves host CPU cycles.
• When support for high session density or high transactions per second is required. Up to 16,000 sessions are
supported per CIP/CPA card.
This support makes the TN3270 Server an enterprise-wide 3270 access solution.
