Release Notes for Cisco IOS
Release 12.0

September 11, 2000

Cisco IOS Release 12.0(13)

Text Part Number 78-6035-13

Note   You can find the most current Cisco IOS documentation on Cisco Connection Online (CCO). These electronic documents may contain updates and modifications made after the hardcopy documents were printed.

These release notes support Cisco IOS Release 12.0. These release notes are updated to describe new memory requirements, hardware support, software platform deferrals, and changes to the microcode or modem code and related documents.

Cisco IOS Release 12.0(8) and all subsequent 12.0 releases are deemed "Generally Deployable." Cisco believes Release 12.0 is suitable for deployment anywhere in the network where the features and functionality of the release are required.

For a list of the software caveats that apply to Cisco IOS Release 12.0, refer to Caveats for Cisco IOS Release 12.0. This caveats document is updated for every maintenance release and is located on Cisco Connection Online (CCO) and the Documentation CD-ROM.

Memory Recommendations

For Cisco routers to take advantage of the Release 12.0 features, you need to have the code or main system memory as listed in Table 1. If you do not, you must upgrade your memory. Some platforms have specific chip or architecture requirements that affect what can be upgraded and in what increments.

The memory recommendations listed in Table 1 are minimum recommendations. Your specific hardware configuration and the software features you choose to deploy could require you to have more memory.

For more information, please see Memory Requirement Update: Cisco 7500 Series at http://www.cisco.com/warp/public/cc/cisco/mkt/core/7500/prodlit/mmry_wp.htm.

Hardware Supported

Cisco IOS Release 12.0 supports the following Cisco hardware platforms:

Cisco 1003 and Cisco 1004 series	Cisco 4500 and Cisco 4700 series
Cisco 1005 series	Cisco Catalyst 5000 series
Cisco 1600 series	Cisco AS5200 series

1Cisco 7000 series routers (Cisco 7000 and Cisco 7010) upgraded with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI)

Note   The Cisco 7000 series previously included the Cisco 7000 and 7010. These products are not supported in Cisco IOS Release 12.0. However, with a Route/Switch Processor (RSP) upgrade, the Cisco 7000 and 7010 are essentially converted to a Cisco 7500. Image names for this enhanced platform begin with "rsp-", and the platform abbreviation is "7500/RSP." All references to Cisco 7500 series routers (excluding specific slot and port references) refer also to the Cisco 7000 and 7010 equipped with the RSP7000 processor and the RSP7000 Chassis Interface (CI). These products are supported in Cisco IOS Release 12.0. For more information, see the section on 11.

Cisco IOS Release12.0(1a) on the Catalyst 5000 Route Switch Module (RSM) platform supports the port adapters listed in Table 2:

Microcode Software

Table 3 lists the current microcode versions for the Cisco 7500/RSP series. This series includes the Cisco 7000 equipped with the RSP7000 processor, the Cisco 7010 equipped with the RSP7000 processor, and the Cisco 7500 series routers. Note that microcode software images are bundled with the system software image, with the exception of the Channel Interface Processor (CIP) microcode (all system software images) and Versatile Interface Processor (VIP) microcode (certain system software images). Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards. Versatile Interface Processor (VIP and VIP2) microcode is bundled into all Cisco 7500 series feature sets listed in , and .

For further information about the CIP microcode, refer to the Cisco document Channel Interface Processor (CIP) Microcode Release Note and Microcode Upgrade Instructions.

Microcode Revision History

The following sections provide revision summaries for microcode for the following routers:

• Cisco 7000 series routers using a Route Processor/Silicon Switch Processor (RP/SSP) or Route Processor/Switch Processor (RP/SP) combination

• Cisco 7500 series routers and Cisco 7000 series routers using an RSP7000

ATM Interface Processor (AIP) Microcode Revision Summary

These AIP Microcode versions fix the following caveats:

• Version 20.14—AIP driver rejects Teardown VC command [CSCdj20667].

• Version 20.15—OIR of any card with cip in box causes problems [CSCdj37259].

• Version 20.16—AIP forwards giants to RSP causing RSP crash at rsp_free_mamd-pak [CSCdj59745].

• Version 20.17—mroute corruption in AIP [CSCdj82421].

• Version 20.18—AIP applies incorrect physical format on Book Tree 8222 framer [CSCdj90325].

Channel Interface Processor (CIP/CIP2) Microcode Revision Summary

CIP/CIP2 Microcode Version 26.16 fixes the following caveats:

• CIP Fatal Error=09 [CSCdr07060].

• CIP Fatal Error=35 occurs when you run the maximum number of sessions on an Enterprise Systems Connection (ESCON) Channel Port Adapter (ECPA) [CSCdr07326].

• After an initial program load (IPL), a Cisco MultiPath Channel (CMPC) connection does not reactivate unless the virtual telecommunications access method (VTAM) major node is recycled. [CSCdr07387].

• The following "bad timer" message appears when you start a TN3270 server:

  %TN3270S-6-BADTIMER: Bad timer operation(0),ra=80C1A5E4,funcPtr=80C1 [CSCdr11353].

• The secondary logical unit (SLU) name is missing on a positive BIND response Route Switch Processor (RSP) [CSCdr42284].

• Non-RFC compliant-negotiation exchanges may cause a CIP Fatal Error=35 in the TN server code because of a NULL pointer reference. [CSCdr64719].

• Systems Network Architecture (SNA) physical unit 5 to physical unit 5 session fails to recover because of incomplete CIP cleanup [CSCdr65638].

• A Cisco AS400 access server TN3270 client adds an invalid termtype of IBM-3486-BA. [Cdr65906].

• Cisco Multipath Channel (CMPC) Transmission Groups (TGs) may get stuck in the SAttachSapPending State[CSCdr87920].

Ethernet Interface Processor (EIP) Microcode Revision Summary

EIP Microcode Version 20.6 fixes the following caveat:

• A corrupted frame is seen on RSP Ethernet under heavy load [CSCdk34545].

Fast Ethernet Interface Processor (FEIP) Microcode Revision Summary

FEIP Microcode Version 20.8 fixes the following caveat:

• The FastEthernet interface stays up even when no MII transceiver and keepalives exist. If "no keepalive" (or keepalive 0) is configured on FastEthernet, the line will stay up even though the Media-Independent Interface (MII) is removed or the cable is disconnected. If the interface is then reconfigured with "keepalive" (of nonzero value) while the physical media stayed down, the link would still indicate up. The only workaround is to issue the command shutdown followed by no shutdown, or the clear interface command. [CSdk66019]
