New and Changed Information
The following sections list the new hardware and software features supported by the Cisco 3600 series routers in Cisco IOS Release 11.3 NA.
New Features in Releases 11.3(7)NA through 11.3(11)NA
There are no new features supported by the Cisco 3600 series routers in these releases.
New Software Features in Release 11.3(6)NA2
The following new software features are supported by the Cisco 3600 series routers in Cisco IOS Release 11.3(6)NA2.
H.323 Voice over IP Gatekeeper
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.
HSRP Support
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.
E.164 Address Support
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
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.
New Features in Releases 11.3(4)NA through 11.3(6)NA
There were no new features supported by the Cisco 3600 series routers in these releases.
New Features in Release 11.3(3)NA
Cisco IOS Release 11.3(3)NA was not released.
New Software Features in Release 11.3(2)NA
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.
Multimedia Conference Manager
The Multimedia Conference Manager feature for Cisco 3600 series routers for Cisco IOS Release 11.3(2)NA is offered in the IP Standard Feature Set described as follows.
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:
•
•
•
•
H.323 Proxy
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.
Limitations and Restrictions
The limitations described in this section apply to this special release.
SNMP Support for Multimedia Conference Manager
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.
One Gateway per Zone
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.
One Proxy per Zone
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.
No Voice Gateways
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.
Only One Local-Zone Declaration Supported
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.

Image Deferral, Cisco IOS Release 11.3(8)T
Cisco IOS Release 11.3(8)T was deferred to Release 11.3(8)T1 on all software images to incorporate corrections to the following caveats:
•
•

Service & Support: Online Technical Support: Software Bug Toolkit: Bug Navigator II
Use as a Dedicated Router Only
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.
Enabling the Release Special Image
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.
ATM Multipoint Signaling
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.
Enabling IPX Routing
Whenever IPX routing is enabled, the Token Ring interface resets.
Forwarding of Locally Sourced AppleTalk Packets
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.
Missing Source-Route Bridging Commands
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.
New TACACS+ Attribute-Value Pair
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 {Using LAN Emulation
Note the following information regarding the LAN Emulation (LANE) feature in Cisco IOS Release 11.3:
•
•
•

•
Deprecated MIBs
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.
Caveats
Caveats describe unexpected behavior or defects in Cisco IOS software releases. This section only contains open and resolved caveats for the current Cisco IOS maintenance release.
All caveats in Release 11.3 and Release 11.3 T are also in Release 11.3(11)NA.
For information on caveats in Cisco IOS Release 11.3, refer to the "Important Notes and Caveats for Release 11.3" section in the cross-platform Release Notes for Cisco IOS Release 11.3 document, which is located on CCO and the Documentation CD-ROM. These release notes list severity 1 and 2 caveats affecting all maintenance releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.
For information on caveats in Cisco IOS Release 11.3 T, refer to the Caveats for Cisco IOS Release 11.3 T document, which is located on CCO and the Documentation CD-ROM.
Note
Open Caveats—Release 11.3(1)NA through 11.3(11)NA
This section describes possibly unexpected behavior by Release 11.3(11)NA. Unless otherwise noted, these caveats apply to all 11.3 releases up to and including 11.3(11)NA.
Miscellaneous
•
The latest versions of Smart Modular and Sharp Flash cards used to store Diagnostics and IOS SW images can report unrecoverable write errors.
Affected Flash cards use a new Sharp (LH28F016SCT) chip set. The original Smart Modular and Intel Flash cards are not affected.
Affected platforms are 7200 and all derivatives, 7500, GSR, and maybe others.
There is no workaround. If the problem occurs, try to reformat the Flash, store less images, or try storing images in a different order. This may help under some circumstances.
•
When running 11.3(10)NA image, ingress gw can display wrong cause code.
•
This fixes CM status display in CMTS when the modem goes offline with BPI turned on and key expiration.
Resolved Caveats—Release 11.3(11)NA
All the caveats listed in this section are resolved in Release 11.3(11)NA. This section describes only severity 1 and 2 caveats.
Basic System Services
•
Certain Internetwork Status Monitor (ISM) NetView users can issue non-enable mode commands without router authentication. Users accessing the router through NetView must be authenticated through NetView's security methods, which can include RACF and SAF. Mainframe users can be restricted from issuing any router commands by the restriction of the RUNCMD within NetView. Users issuing enable mode commands must be authorized to issue this level of command by ISM, and must possess the ENABLE mode password. If the router is controlled by TACACS+, the ISM user must have a TACACS+ User ID and Password to issue enable level commands.
show user : command has been modified : the user field is filled up by the host name.
Two options have been added to the following commands : sna host and dspu host.
The options are: no-enable and high-security.
Configure these options with focalpoint.
no-enable : when this is set, it does not allow enable command from the host
high-security : when this is set, it allows the following commands in USER mode. (PRIVILEGE mode is not affected by this option.) You must enter all these commands in full or else the command will not be allowed (that is, sh versi is not allowed for show version)
DECnet
•
When decnet accounting is implemented, it's possible for the router to crash depending on the amount of connections.
•
When you are configuring Decnet on a router, you can specify an Address Translation Gateway (ATG) network number in the range 0 to 3. If the ATG-network-number is specified incorrectly while configuring an interface, the router will reload.
If the ATG-network-number is not required the problem will not occur.
If the ATG-network-number is required, then a workaround is to ensure that the ATG-network-number specified when enabling an interface matches the ATG-network-number specified when decnet routing is enabled globally; for example:
decnet 1 routing 2.3 interface ethernet 0/0 decnet 1 cost 5
EXEC and Configuration Parser
•
If the length of the entire command after completion exceeds PARSEBUF, then the router crashes
Fix: Don't allow the "command completion" if it exceeds PARSEBUF
IBM Connectivity
•
Console message flooding may occur when an XID3 loop occurs with APPN in the router. The following messages are repeated for each iteration of the loop:
%APPN-3-logcsCS_XXXXIP11_LOGMSG_01: CS - Sending Alert to MS, sense_code = 83E0001, proc_name = XXXXIP32, port_name = HMAC04, ls_name = @LS00289 %APPN-3-logcsCS_XXXXIP11_LOGMSG_03: CS - Associated outbound XID data in alert (length >= 29): %APPN-3-Error: 327307700000000000F7C1000000008000010B510005000000000007000E11F4C4C5C2E5D4E4F0F04BD5D5C 3C9D7F0F110380037110C0804F1F2F0F0F0F00908F0F0F0F0F0F0F01406C3C9E2C3D640C1D7D7D540D5D561 C4D3E4D90F0FC3C9E2C3D640C1D7D7D540D5D52207000000083E0001 %APPN-3-logcsCS_XXXXIP11_LOGMSG_05: CS - Associated inbound XID data in alert (length >= 29): %APPN-3-Error: 326705D56F010000B00810000000000000010B410005B800000000070010370023110C0804F0F3F0F0F0F00 F06D4E240E2D5C140E2C5D9E5C5D90908F0F0F0F0F0F0F0131103100010F0F0F0F0F0F0F0F0F0F0F0F0F00E 0FF4C4C5C2E5D4E4F0F04BC3E3F5F6C6Avoid console logging.
•
The router crashes with bus error when executing a show dlsw circuit command if there is a circuit with a local rif of 18 bytes.
This is a regression introduced by CSCdk83294.
•
DLSw Lite peers leak CLS connect request buffers. If possible, try using a different peer type. This patch frees an outstanding connect request if additional requests are received while the first request is still pending.
Interfaces and Bridging
•
SYMPTOM: Crash in frf9_preComp()
This ondition most frequently occurs during times when router traffic is heavy, which causes memory usage to increase and a possible low-memory condition to occur.
WORKAROUND: Disable compression or use a different type.
Since this problem is aggravated by a low-memory condition, tuning the memory can prevent this condition from occurring, but there are no guarantees.
•
This is caused by an over-write issue in bss area with FDDI modules equipped which has potential to cause serious problem such as crash in 12.0T.
•
A PA-4R-DTR port may reset under the following circumstances:
1) A high rate of traffic is traversing the port (200 pps or better) .
2) The PA-4R-DTR port is the active monitor of the physical ring.
3) An event on the ring forces the active monitor to purge the ring.
When this problem occurs, the PA-4R-DTR port resets, and the ring experiences a beacon.
Workaround: Make sure the DTR port is not the active monitor on the ring. This can be done by ensuring that the mac-address of the DTR card is not the highest mac-address on the physical ring.
IP Routing Protocols
•
IP access lists fail to block pings on the interfaces configured for policy routing with IP route-cache policy.
•
ARP to a router fails on the serial interface when bridging is enabled and after the router is reloaded.
----eth---2500---serial---2500---eth---Router : 2500 IOS : 112.(17), 12.0(3.7)
Workaround: Remove IP address on serial and enter again.
•
Some IP fragments may be incorrectly filtered out by access lists.
•
DNS replies passing from "inside" to "outside" through NAT are not NAT translated correctly in many cases. There is no work around.
Miscellaneous
•
Symptom: The NM-1FE-TX fails to autonegotiate properly when connected through an SMF connector.
Analysis: Manually setting the speed to 100 solves the problem. An interface speed command with the following syntax is being added to overcome this. The default behaviour would be to autonegotiate:
[no] speed {10 | 100 | auto}•
When port info is passed from LAC and 'vpdn aaa attribute nas-port vpdn-nas' is configured, it should be mapped to the correct NAS-Port-Type value.

Configuring ppp encaplusation on an interface and making that interface a member of a bridge group gives "tracebacks" and "fair-queue not initialized properly" messages. Remove bridging from the interface or turn off fair queueand the massages dissappear.

Under stressful conditions of (if the ESA is bringing up a large number of crypto sessions simultaneously), it may either enter a race condition or get the crypto initiation messages wedged in the input-q of the interface doing encryption.
•
After the router is reloaded, ESA can not re-establish active crypto connection. The workaround is to remove the crpto map, reload the the router again, and reapply the crypto map.

Problem description: When cable ip-broadcast-echo is enabled, under certain timing conditions, it may cause a buffer leak.
Workaround: Do not enable cable ip-broadcast-echo and cable ip-multicast-echo.

DDR with dialer dtr does not reset DTR to a down state after an unsuccessful call attempt. Unsuccessful in this case means that DD; therefore DCD does not come up.
This can be verified by viewing show dialer to ensure that the dialer state is idle; then enter show interface serial x to check the state of DTR.
•
When the router is operating as an X.25 switch and forwards an X.25 call containing certain facilities not interpreted by the router, the facility values can be corrupted. The problem most likely occurs when the call cannot be forwarded immediately (i.e., when using X25-over-TCP) with heavy traffic; the affected facilities include any local facilities and the Charging Information facility.
•
A router performing X.25 switching may reload when clearing many calls simultaneously during heavy traffic.
•
Customer repeatedly crashes (segV) when dialer rotor best is configured and 'deb dialer' is started once the traffic triggers a call.
•
Reliable PPP can cause an intermittent crash when used with WFQ. Workaround is to disable Reliable PPP or WFQ.
•
The router configured for dialer watch never dials back when backup interface times out if Watched route on dialer watch is not installed in routing table.
