Caution Cisco IOS images with strong encryption (including, but not limited to, 168-bit [3DES] data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders can be denied or subject to delay due to Unites States government regulations. When applicable, obtain local import and use authorizations for all encryption strengths. Contact your sales representative or distributor for more information, or send e-mail to export@cisco.com.

²Enterprise is available with APPN in a separate feature set. APPN includes APPN Central Registration (CRR) and APPN over DLSw+. APPN is not available on the AccessPro PC Card.

³This feature includes AppleTalk load balancing.

⁴IRB supports IP, IPX, and AppleTalk; it is supported for transparent bridging, but not for SRB; it is supported on all media-type interfaces except X.25 and ISDN bridged interfaces; and IRB and concurrent routing and bridging (CRB) cannot operate at the same time.

⁵The Novell IPX feature includes displaying SAP by name, IPX Access Control List violation logging, and plain-English IPX access lists.

⁶Translational bridging is fast switched by default but can be disabled.

⁷Note that the only IPX encapsulation supported in ISL is IEEE 802.3.

⁸ATM LAN emulation for Banyan VINES is only supported in Enterprise. The Desktop feature set supports DECnet only.

⁹ISDN support includes calling line identification (ANI), X.25 over the B channel, ISDN subaddressing, and applicable WAN optimization features.

¹⁰PPP includes support for LAN protocols supported by the feature set, address negotiation, PAP and CHAP authentication, Multilink PPP, and PPP compression.

¹¹X.25 includes X.25 switching.

¹²IPX header compression (RFC 1553) is available in the feature sets that support IPX.

¹³BGP4 includes soft configuration, multipath support, and prefix filtering with inbound route maps.

¹⁴RED and RSVP are supported in IP/IPX/IBM/APPN for the Cisco 4000, Cisco 4500, and Cisco 4700 only.

¹⁵The RMON events and alarms groups are supported on all interfaces. Full RMON support is available with the Plus feature sets.

¹⁶For more details, see the description of the new data encryption options in the section "Cisco IOS Packaging" in the Release Notes for Cisco IOS Release 11.2. (See the "Related Documentation" section for information on accessing the related release notes.)

¹⁷TACACS+ Single Connection and TACACS+ SENDAUTH enhancements are supported.

¹⁸Cisco IOS Release 11.2 introduces several DLSw+ enhancements available in the Plus, Plus 40, and Plus 56 feature sets.

¹⁹SRB/RSRB is fast switched. This enhancement is on by default, but it can be disabled.

²⁰These features are supported on access servers (with limited support on router auxiliary ports).

²¹The Cisco 4000, Cisco 4500, and Cisco 4700 products do not support ARAP 1.0/2.0.

²²Use of LAT requires terminal license (FR-L8-10.X= for an 8-user license or FR-L16-10.X= for a 16-user license).

Important Notes

The following sections contain important notes about Cisco IOS Release 11.2 and apply to the Cisco 4000 series.

Cisco IOS Release 11.2(15a) and 11.2(15a)P

After the release of Cisco IOS Release 11.2(15) and 11.2(15)P, a serious defect (caveat CSCdk33475) was identified that impacts Enhanced IGRP for Cisco IOS Releases 11.2(14.1) through 11.2(15.2) and Releases 11.2(14.1)P through 11.2(15.2)P. It was determined that this defect was significant enough to merit a software rebuild. The rebuild includes the caveat fix and is renumbered to 11.2(15a) and 11.2(15a) P.

Caveat CSCdk33475 causes a router to fail after the command show ip eigrp events is entered. While this show command is not required for normal operation, its use might present difficulties for customers who are running images with this defect.

Release 11.2(15a) and Release 11.2(15a)P and all subsequent releases of Cisco IOS software, including Release 11.2(16) and Release 11.2(16)P, include the fix for this caveat.

Cisco IOS Release 11.2 Switches to Long-Cycle Maintenance Releases

Beginning with Cisco IOS Release 11.2(15) and Release 11.2(15)P, all subsequent 11.2 and 11.2 P releases switch to Long-Cycle Maintenance Releases. A new 11.2 and 11.2 P maintenance release is scheduled to be available every thirteen weeks during the Long-Cycle Maintenance Release period. Interim builds will be available approximately every two weeks.

Caveats

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only select severity 3 caveats are included in the caveats document.

For information on caveats in Cisco IOS Release 11.2, see Cross-Platform Release Notes for Cisco IOS Release 11.2 located on Cisco.com and the Documentation CD-ROM, that describes caveats affecting all maintenance releases.

Note If you have an account with Cisco.com, you can use Bug Navigator II to find caveats of any severity for any release. You can reach Bug Navigator II on Cisco.com at Software Center: Cisco IOS Software: Cisco Bug Toolkit: Cisco Bugtool Navigator II, or at http://www.cisco.com/support/bugtools.
