Release Notes for the Cisco 4000 Series for Cisco IOS Release 11.2 P

April 16, 2001

Note Cisco IOS Release 11.2(26)P is the last scheduled maintenance release for Cisco IOS 11.2 P. TAC support will continue to be available. These release notes will be the last release notes published for Cisco IOS Release 11.2 P.

Note You can find the most current Cisco IOS documentation on Cisco.com. These electronic documents can contain updates and modifications made after the hardcopy documents were printed.

These release notes for the Cisco 4000 series support Cisco IOS Release 11.2 P, up to and including Cisco IOS Release 11.2(26)P. These release notes are updated as needed to describe new memory recommendations, new features, new hardware support, software platform deferrals, and changes to the microcode or modem code and related documents.

For a list of all the software caveats that apply to Cisco IOS Release 11.2(26)P, see Caveats for Cisco IOS Release 11.2 P that accompanies these release notes. The caveats document is updated for every maintenance release and is also located on Cisco.com and the Documentation CD-ROM.

Use these release notes with Cross-Platform Release Notes for Cisco IOS Release 11.2 on Cisco.com and the Documentation CD-ROM.

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.

Table 4 Table 4 lists the features and feature sets supported by the Cisco 4000 series in Cisco IOS Release 11.2 P and uses the following conventions:

•No—This feature is not offered in the feature set.

•Basic—This feature is offered in the basic feature set.

•Plus—This feature is offered in the Plus feature set.

•Encrypt—This feature is offered in the encryption feature sets, which consist of 40-bit (Plus 40) or 56-bit (Plus 56) data encryption feature sets.

Note This table might not be cumulative or list all the features in each image. You can find the most current Cisco IOS documentation on Cisco.com. These electronic documents can contain updates and modifications made after the hardcopy documents were printed. If you have a Cisco.com login account, you can find image and release information regarding features prior to Cisco IOS Release 11.2(26)P by using the Feature Navigator tool at: http://www.cisco.com/go/fn.

¹This feature set has no additional options. It offers a low-end APPN solution for this set of hardware platforms. This feature set is not available for AccessPro PC cards.

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 display 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 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, 4500, and 4700 only.

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

¹⁶MAC security for hubs is applicable to the following Cisco 2500 series Ethernet hub models: Cisco 2505, 2507, 2516, and 2518.

¹⁷For 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.)

¹⁸TACACS+ Single Connection and TACACS+ SENDAUTH enhancements are supported.

¹⁹Cisco IOS Release 11.2 introduces several DLSw+ enhancements available in the Plus, Plus 40, and Plus 56 feature sets.

²⁰SRB/RSRB is fast switched. This enhancement is on by default, but can be disabled.

²¹This feature is supported on access servers (with limited support on router auxiliary ports).

²²The Cisco 4000, 4500, and 4700 products do not support ARAP 1.0/2.0.

²³Use of LAT requires terminal license (FR-L8-10.X= for an 8-user license or FR-L16-10.X= for a 16-user license).

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 P, refer to the Caveats for Cisco IOS Release 11.2 P located on Cisco.com and the Documentation CD-ROM.

All caveats in Cisco IOS Release 11.2 are also in Cisco IOS Release 11.2 P.

For information on caveats in Cisco IOS Release 11.2, refer to the "Caveats" section in the Cross-Platform Release Notes for Cisco IOS Release 11.2 on Cisco.com and the Documentation CD-ROM. These release notes list severity 1 and 2 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 & Support: Online Technical Support: Software Bug Toolkit or at http://www.cisco.com/support/bugtools.
