The Cisco IOS Software Release Upgrade Paths and Packaging Simplification product bulletin does not contain information specific to Cisco IOS Release 11.3 NA, but provides general upgrade information that may apply to Cisco IOS Release 11.3 NA.
The Cisco IOS software is packaged in feature sets consisting of software images---depending on the platform. Each feature set contains a specific set of Cisco IOS features.
This section lists Cisco IOS software features available in Cisco IOS Release 11.3(11)NA.
The following sections list the new hardware and software features supported by the Cisco 3600 series routers in Cisco IOS Release 11.3 NA.
There are no new features supported by the Cisco 3600 series routers in these releases.
The following new software features are supported by the Cisco 3600 series routers in Cisco IOS Release 11.3(6)NA2.
The Gatekeeper can manage a zone and provide bandwidth management and address registration services to gateways that are present in the network. The Gatekeeper manages H.323 endpoints in a consistent manner, allowing them to register with a gatekeeper and to locate another gatekeeper. The Gatekeeper provides logic variables for proxies or gateways in a call path to provide connectivity with the public switched telephone network (PSTN), to improve Quality of Service (QoS), and to enforce security policies. Multiple gatekeepers may be configured to communicate with one another, either by integrating their addressing into Domain Naming System (DNS), or via Cisco IOS configuration options.
Gatekeeper HSRP (Hot Standby Router Protocol) support consists of elements that affect both the gateway and gatekeeper functions in the router. The gateway periodically retries its registration when it detects a possible gatekeeper failure, in order to register itself with the backup gatekeeper. The backup gatekeeper normally operates in a passive mode in which it does not accept registrations, and becomes active only when it is notified by HSRP that it must become the primary gatekeeper.
There are two types of addresses used in H.323 destination calls:
The Cisco IOS Release 11.3(2)NA software feature Multimedia Conference Manager dealt primarily with H.323-ID addressing in interzone calls. With the new prefix commands, the administrator can now also configure interzone routing when calls are made using E.164 addresses.
Technology prefixes are designed to enable the use of E.164 address routing. E.164 is an International Telecommunications Union (ITU) specification for the ISDN international telephone numbering plan, which has traditionally only been used in telephone networks. These prefixes identify gateways that have specific capabilities within a given zone. They are handled specially in that the technology prefixes are ignored during the zone selection process and then examined for gateway selection within the zone.
There were no new features supported by the Cisco 3600 series routers in these releases.
Cisco IOS Release 11.3(3)NA was not released.
The following new software features are supported by the Cisco 3600 series routers in Release 11.3(2)NA. The special Cisco IOS Release 11.3(2)NA image for Cisco 3600 series routers was not designed to perform as standard Cisco 3600 series router Cisco IOS software.
Cisco Multimedia Conference Manager provides network administrators with a mechanism to support ITU-T H.323 applications without impacting the mission-critical applications that are running on today's networks. Multimedia Conference Manager also provides the mechanism to implement security for H.323 communications. The image has specialized features designed specifically for the Multimedia Conference Manager feature (gatekeeper and proxy conforming to ITU-T H.323).
H.323 Multimedia Conference Manager, implemented on Cisco IOS software, provides the network administrator with the ability to do the following:
The H.323 gatekeeper is an infrastructure component defined by the ITU H.323 standard. It provides call routing functionality for H.323 endpoints, provides simple bandwidth management for H.323, and adds authentication, authorization, and accounting functionality for H.323 calls.
The H.323 proxy is included in the Multimedia Conference Manager feature. The H.323 proxy is a boundary device that terminates all H.323 calls from the local LAN/Zone and can establish sessions with H.323 endpoints that are in a different LAN/Zone. In doing so, the proxy provides the administrator the ability to set and enforce Quality of Service (QoS) policy on WAN segments, and provides a method to tag H.323 traffic for tunneling through firewalls.
The limitations described in this section apply to this special release.
The H.323 gatekeeper and proxy features in this release currently do not support SNMP-based management. All standard features in this release do include support for SNMP-based management.
The current Cisco gatekeeper supports only one gateway per zone. More than one gateway is allowed to register per zone; however calls are not forwarded to that gateway.
The current Cisco gatekeeper supports only one H.323 proxy per zone. More than one proxy is allowed to register per zone; however, calls are not forwarded to that proxy.
The current Cisco gatekeeper supports only H.320 gateways. Voice gateways are not supported. Voice gateways are allowed to register; however, calls are not forwarded to them.
The current Cisco gatekeeper supports only one local-zone declaration. Declarations of more than one local zone in the Cisco gatekeeper are flagged as errors.
The following section applies to Cisco IOS Release 11.3 NA up to and including Cisco IOS Release 11.3(11)NA.
 | Caution In certain countries, use of these products or provision of voice telephony over the Internet may be prohibited and/or subject to laws, regulations or licenses, including requirements applicable to the use of the products under telecommunications and other laws and regulations; customers must comply with all such applicable laws in the country(ies) where they intend to use the products. |
End of Engineering (EOE) means there are no more regularly scheduled maintenance releases. The last maintenance release scheduled on the EOE date is only available through CCO and Field Service Operations---not through manufacturing.
EOS and EOE releases are subject to change. For the most up-to-date information on the status of EOS or EOE, refer to the End of Sales and End of Engineering for Cisco IOS Software Releases product bulletins located on CCO.
Ongoing support for functionality in Releases 11.3, 11.3 NA, and 11.3 T is available in Cisco IOS Release 12.0(3)T and later maintenance releases of Cisco IOS Release 12.0.

Service & Support: Online Technical Support: Software Bug Toolkit: Bug Navigator II
A Cisco 3600 series router using the Multimedia Conference Manager feature is designed to be used as a dedicated router. Do not use the Multimedia Conference Manager on a regular router. The Multimedia Conference Manager can take up a significant amount of CPU process time when a H.323 call is being established through the proxy. The impact of the call establishment on the routing performance is not currently fully determined; however, it is advisable that a Cisco 3600 series router with Multimedia Conference Manager not be used as a regular router.
The special Cisco IOS Release 11.3(2)NA image for Cisco 3600 series routers was not designed to perform as standard Cisco 3600 series router Cisco IOS software. The image has specialized features designed specifically for the Multimedia Conference Manager feature (gatekeeper and proxy conforming to H.323). Be sure to enable these features on routers running this release. Multimedia Conference Manager is briefly described in the previous section. For more information, see the Multimedia Conference Manager feature online documentation. See the "Related Documentation" section.
Prior to Cisco IOS Release 11.1(13) and 11.2(8), the atm multipoint-signaling command was used on the main interface and affected all subinterfaces. For Release 11.1(13), 11.2(8), and later releases (including Release 11.3), explicit configuration on each subinterface is required to obtain the same functionality. Refer to caveat CSCdj20944, which is described as follows:
The atm multipoint-signaling interface command is currently only available on the main ATM interface. The effect is that signaling behavior (point-to-point or point-to-multipoint) for all clients on all subinterfaces is determined by the command on the main interface.
Clients on different subinterfaces can have different behavior. Specifically, 1577 requires point-to-point, and PIM allows point-to-multipoint. The command should be on a per subinterface basis.
Enable the atm multipoint-signaling command on all subinterfaces that require it. Previously, you only needed to enable the command on the main interface.
Whenever IPX routing is enabled, the Token Ring interface resets.
Cisco's implementation of AppleTalk does not forward packets with local-source and destination network addresses. This behavior does not conform to the definition of AppleTalk in Apple Computer's Inside AppleTalk publication. However, this behavior is designed to prevent any possible corruption of the AppleTalk Address Resolution Protocol (AARP) table in any AppleTalk node that collects MAC-addresses.
Due to a production problem, many source-route bridging commands were omitted from the printed version of the Cisco IOS Software Command Summary (78-4746-XX). For documentation of all source-route bridging commands, refer to the Bridging and IBM Networking Command Reference (78-4743-XX). You can also obtain the most current documentation on CCO or on the Documentation CD-ROM.
A new authorization feature that allows you to separately configure and authorize Multilink PPP was added in Cisco IOS Release 11.3(1). This feature can cause MLP authorization to fail in TACACS+ servers that do not include the relevant authorization permissions in the configuration.
For TACACS+, add the following attribute-value (AV) pair for all users who are allowed to negotiate Multilink PPP:
service = ppp protocol = multilink {
Note the following information regarding the LAN Emulation (LANE) feature in Cisco IOS Release 11.3:
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBS are currently being migrated into more scalable MIBs---without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in the following table.
