Microcode Software

Note that microcode software images are bundled with the system software image. Bundling
eliminates the need to store separate microcode images. When the router starts up, the system
software unpacks the microcode software bundle and loads the proper software on all the interface
processor boards.

New Software Features in 11.0(10)BT

The TN3270 server is a new feature on the CIP of the Cisco 7000 family of routers. The TN3270
server allows TN3270 clients access to IBM and IBM-compatible mainframes. It can reduce the
cycles spent by the mainframe on TCP/IP and TN3270 processing by a factor of ten or more and
off-load the TCP/IP and TN3270 cycles from the mainframe.
The TN3270 server supports up to 8000 (CIP1) or up to 16000 (CIP2) concurrent sessions, while
most external gateway solutions can support only 1000 to 2000 sessions. The TN3270 server offers
the following capabilities:
•

•
TN3270 server requires 32 MB of CIP dynamic RAM to support up to 4000 sessions, 64 MB to
support 8000 sessions, and 128 MB to support 16000 sessions (CIP2 only). TN3270 server can run
concurrently with any of the other CIP applications (IP Datagram, TCP/IP Offload, or CIP SNA
(CSNA)), but operation of any of these features will affect the total number of sessions supported
because of contention for CIP processor cycles.
Update to Configuration Guide
The information that follows is an update to the Router Products Configuration Guide, Chapters 23

Load Balancing and Redundancy—Provides effective CIP resource utilization and more
consistent response times. (This feature is initially provided by means of an external, prototype
implementation.)
End-to-End Session Visibility—Provides enhanced resource management.
Systems Network Architecture (SNA) Session Switching—Off-loads VTAM by providing
session routing.
TN3270E Support—In combination with a TN3270E client, provides advanced SNA
management and SNA functionality, including printer support.
Dynamic Definition of Dependent Logical Units (LU)—Provides simplified configuration and
network definition at the router and in VTAM.
Dynamic Allocation of LUs—Makes efficient use of LU pool resources while supporting
multiple SNA model types.
