Determining the Software Version

To determine the version of Cisco IOS software running on your Cisco 7000 family router, log in to the Cisco 7000 family router and enter the show version EXEC command. The following sample show version command output is from a router running a Cisco 7200 series software image with Cisco IOS Release 12.2(2)XB15:

Router> show version
Cisco Internetwork Operating System Software
IOS (tm) 7200 Software (c7200-is-mz), Version 12.2(2)XB15, RELEASE SOFTWARE

Upgrading to a New Software Release

For general information about upgrading to a new software release, refer to Upgrading the Cisco IOS Software Release in Cisco Routers and Modems located at:

http://www.cisco.com/warp/public/620/6.html

Feature Set Tables

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.

Cisco IOS Release 12.2(2)XB15 supports the same feature sets as Cisco IOS Release 12.2, but Cisco IOS Release 12.2(2)XB15 can include new features supported by the Cisco 7000 family.


Caution Cisco IOS images with strong encryption (including, but not limited to, 168-bit Triple Data Encryption Standard [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 may be denied or subject to delay because of United States government regulations. When applicable, purchaser and user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Table 2 lists the feature and feature set supported by the Cisco 7200 series routers in Cisco IOS Release 12.2(2)XB.

The table uses the following conventions:

Yes—The feature is supported in the software image.

No—The feature is not supported in the software image.

In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, (2)XB3 means a feature was introduced in 12.2(2)XB3. If a cell in this column is empty, the feature was included in the initial base release.


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 may contain updates and modifications made after the hard-copy documents were printed.

New Software Features in Cisco IOS Release 12.2(2)XB

The following new software feature is supported by in Cisco IOS Release 12.2(2)XB:

Survivable Remote Site Telephony

Platforms: Cisco 7200 series routers.

The Survivable Remote Site (SRS) Telephony feature, under the IP Telephony services umbrella, provides the Cisco CallManager with fallback support for the Cisco IP phones attached to the Cisco router on your local Ethernet. The SRS Telephony feature enables the routers to provide call handling support for the Cisco IP phones when the Cisco IP phones lose connection to the remote primary, secondary, or tertiary Cisco CallManager or when the WAN connection is down.

Cisco CallManager 3.0 supports Cisco IP phones at remote sites attached to Cisco branch office multiservice routers across the WAN. Prior to the SRS Telephony feature, when the WAN connection between the remote branch office router and the Cisco CallManager failed or connectivity with the Cisco CallManager was lost for some reason, the Cisco IP phones at the branch office became unusable for the duration of the failure. The SRS Telephony feature overcomes this problem and enables the basic features of the Cisco IP phones by providing call-handling support on the branch office router for its attached Cisco IP phones. The system automatically detects the failure and uses the Simple Network Auto Provisioning (SNAP) technology to autoconfigure the branch office router to provide call processing for the local Cisco IP phones. When the WAN link or connection to the primary Cisco CallManager is restored, call-handling capabilities for the Cisco IP phones switch back to the primary Cisco CallManager. During a failure when SRS Telephony feature is enabled, the Cisco IP phone displays a message to inform you that the Cisco IP phones are in the Cisco CallManager fallback mode and are able to perform limited functions.

Open Caveats—Cisco IOS Release 12.2(2)XB15

This section documents possible unexpected behavior by Cisco IOS Release 12.2(2)XB15 and describes only severity 1 and 2 caveats and select severity 3 caveats.

There are no known open caveats for Cisco IOS Release 12.2(2)XB15.

Resolved Caveats—Cisco IOS Release 12.2(2)XB15

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(2)XB15. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdx76632

Cisco products running IOS contain vulnerabilities in the processing of H.323 messages, which are typically used in packetized voice or multimedia applications. Features such as NAT and IOS Firewall must inspect H.323 messages and may be vulnerable as well.

The port information provided on a 5400/5350/5850 on modems within Radius attribute 5 using either nas-port format a or b for async calls provide the true port information (as in slot/port) and not the TTY line number of the modem which previous generation dial platforms provided. This is causing problems for service providers using a variety of Cisco dial platforms as they are inconsistent in the information being relayed on the various platforms Cisco sells.

There is no known workarounds.

In 12.2(2)XB and 12.2(4)T and later IOS codes, router does not send radius connection accounting attribute 46 for tcp clear calls or for any outbound telnet connections from router. The is issue is only with telnet connections regular ppp calls accounting records do contain this attribute just fine

There are no known workarounds.

CSCdy16593

With 2930 it has been noted that some client modem (most likely a single vendor) will take the modem out of service. The error caused by this modem is not fatal to subsequent calls and should not take down the port. Under this condition the 5300 will recover but this has not been validated with all IOS releases. The 5800 does not recover.

Modems on the AS5800 can appear to take calls even though MICA has placed them out of service. This will lower the effective CSR of the router.

Workaround: Lower the autorecovery threshold of the modems in the configuration. This will allow the lower CSR to trigger a reset of the modems (via reload).

When one creates a view that contains the iso subtree, it cannot be deconfigured: a "no snmp-server view ..." command will leave the view unchanged in the running config. A reload doesn't help either.

This has been tested on customer device (7507) running 12.0.7S1, and in our lab, on a 7513 running 12.0(8)S

This happened all the times, even in IOS versions that have CSCdj84623 fixed. Every view can be deconfigured, except those containing the iso subtree.

There are no known workarounds.

If the IP address is removed from a the PPP interface of a 7500, running 12.1E IOS, and then the IP address is added, this change is not reflected immediately in CEF. This results in 50% packet loss until the background CEF process updates the adjacency.

Workaround: shut / no shut the PPP interface.

Alternative workaround: Disable CEF (not an option as the 7500 is a PE router).

On a PPP multilink bundle that has multiple links, if one of the links departs from the bundle while data is enqueued for output at the bundle interface, the output mechanism on the bundle may stall, halting any further output from that bundle. The output queue on the bundle becomes full, causing packets that are forwarded to that bundle to be dropped and the affected bundle to stop transmitting packets.

There are no known workarounds.

With Resource Pooling and Resource Pooling AAA accounting configured, a customer profile may not be found for a particular DNIS group.

The access server may have a problem with incoming calls finding the customer profile depending on the order, size and value of the dnis entered; results may vary depending on whether the DNIS is manually entered or whether the wavl is set up from reload via the start-up config.

On 7200 running 12.2.6 it is seen that with T1 links combined in a Multilink PPP bundle, and MLPPP fragmentation enabled; ISAKMP keepalives are not being received by the box, even though the remote peer is sending out the keepalive messages. As a result each end thinks its peer is dead and deletes the IKE & IPSEC SA's. They then re-negotiate IKE and IPSEC and create new SA's. As a result, IKE and IPSEC are re-negotiated at each IKE keepalive interval and there is some traffic drop during this re-negotiation phase.

Workaround: Disable hardware crypto acceleration. With software crypto, this problem is not seen.

Alternative workaround: Disable MLPPP fragmentation. Without fragmentation, the IKE keepalives are received by the peers (even with hardware crypto)

When using multichassis multilink, or MLP with VPDN, the box can crash.

Workaround: Do not use MLP.

CSCdw80521

If an access server is configured for resource-pooling with customer profile templates, a short, abnormal call may cause the next call on that modem/interface to bind to multiple profiles causing the configuration for the next call to be different than intended.

A workaround which works under some circumstances (but not all) is to make sure that each customer profile template explicitly specifies every configuration item which may be different on other customer profile templates to make sure the configuration items on the intended template overrides any configuration items on other templates which may be unexpectedly bound. The workaround does not work when multiple short, abnormal calls land on the same port consecutively.

CSCdw80646

Improper call counts on trunk groups when they are used in an SS7 environment. The trunk group may "lose" an active call when the channel is blocked from SS7 and then unblocked, while the call is still active. This would lead to the trunk group showing lesser number of calls than the actual value.

Workaround: Wait until the calls are disconnected, at which time the call count should return to its true value, or remove the trunk from the trunk group and reconfigure it.

CSCdw80687

Packets are process switched on an interface with fast switching configured. This can result in high CPU usage.

Header-compression must be configured, but only on one side. For example, in a dial-in situation, where header-compression is configured on the central switch, but not on the box that is dialling in. Also, the interface must not support FAST switched header-compression, e.g. most dial-in interfaces are currently not supported.

Workaround: Remove header-compression from the configuration.


Note Note: If header-compression is configured on both sides of a link, and the interface does not support fast-switched header-compression, then process switching is normal and required for successful operation of the header-compression feature.

A Cisco router that is running Cisco IOS Release 12.2(5.7)T or a later release and that is acting as a Layer 2 Tunneling Protocol (L2TP) access concentrator (LAC) or L2TP network server (LNS) may fail to process valid L2TP Zero-Length Body Acknowledgement (ZLB ACK) packets. This behavior may cause sessions and tunnels to drop.

There are no known workarounds.

CSCdx02102

A Cisco router may experience memory corruption when configured with software encryption (MPPE) if the MTU size is greater than 8K (and if there are actually packets of length greater than 8K).

Workaround: Configure MTU less than 8K when doing software encryption (MPPE).

CSCdx02525

A Cisco access server running 12.2(3) or 12.2(4)T and later will experience a memory AAA user profiles turn on PPP header or data compression and the router is not configured to use virtual-profiles. CSCdw71698 fixes the issue for ISDN callers, however the leak continues to occur for async callers.

Workaround: Configure virtual-profiles.

CSCdx03583

This problem occurs when we are interacting with MSFT's Phoenix client, and the Client send us a BYE after we've sent it a 200ok (basically, BYE and 200ok cross on the wire). In such a scenario, the MSFT client ACK's our 200ok, and leaves the call hanging (that is, it doesn't send us a BYE, as per spec). Our GW's keep the call up, till the Media Inactivity timer pops, and in effect we're hogging up the resources till then.

Workaround: The work-around is to set a low Media Inactivity timer on the GW's and so the call resources won't be hogged up for too long. This work-around is not applicable for customers who want to set their Media Inactivity Timers to higher values.

CSCdx05704

When a user dials in, requests MSCB and is bound to a dialer profile, after authentication (problem won't happen if the profile is bound before PPP starts) then IOS does not propose the option to skip callback during CBCP even if we are configured for it (ppp callback accept and user has empty callback dial string).

If the user opts to skip the callback anyway, we will drop the call because we did not propose that option, which is correct behavior but has only been enforced since CSCdu55093, which is why this bug has been relatively hidden up until recently.

There are no known workarounds.

There are no known workarounds.

CSCdx22886

SGBP forwarding does not work if VPDN is disabled.

Workaround: Enable VPDN (issue the vpdn enable command) and then disable it immediately (issue no vpdn enable) on all the SGBP stack group members. This allocates the resources required to do SGBP, and at the same time does not require VPDN to be kept enabled.

CSCdx40546

For T.37 offramp fax, the ANI information is currently available only from the message envelope of the email. But in the case that the mail has to be bounced (e.g. invalid fax machine number), the mail cannot be bounced back to the correct account. The call cannot be billed in this case.

There are no known workarounds.

CSCdx41547

A voice gateway running up to version 12.2(2)XB4 configured for SIP and RADIUS will not send the "call-id" VSA to the RADIUS server when calling from telephony to SIP.

The call-id VSA is passed correctly when calling from SIP to telephony.

There are no known workarounds.

An As5400 UUT running XB throttle 4.10.0 nightly image will experience Crash at radius_build_packet() after couple of hours of stress test running Analog, ISDN, L2TP Calls.

There are no known workarounds.

CSCin03065

When an attempt is made to create an additional session that has similar tunnel parameters that are defined by a RADIUS profile (for the same domain, the same user, or a different user), instead of creating a session under the existing tunnel, a new tunnel and a session are created. This condition is observed in Cisco IOS Release 12.2(7.4)T and occurs if the tunnel parameters are defined by RADIUS without either of the following definitions:

Cisco-Avpair vpdn:tunnel-id = "xyz" or Tunnel-Client-Auth-ID = "xyz"

Workaround: Define one of the following definitions under a RADIUS profile when tunnel parameters are defined:

Cisco-Avpair vpdn:tunnel-id = "xyz" or Tunnel-Client-Auth-ID = "xyz"

CSCin06313

as5850 pops out the following error message after boot up:

00:00:38: RM/AUTH: Process (22) failed to register to VPDN

This message is seen with c5850-p9-mz-v122_2_xb_throttle_flo_t.0.4.0 image.

There are no known workarounds.

CSCuk32311

When Cisco Express Forwarding (CEF) is enabled, adjacencies are erroneously added for sessions that have been forwarded using a tunnelling protocol such as L2TP or PPPoE. Adjacencies should only be added for sessions that terminate on the router, and only after the IP Control Protocl (IPCP) has been negotiated.

There are no known workarounds.

CSCuk33327

After RADIUS failover, during EAP, the NAS would try to failover to a new RADIUS server. However, this is forbidden midway through authentication. As such, the NAS was required to restart the authentication process from scratch and allow the user another attempt to authenticate.

There are no known workarounds.

Network access server (NAS) may fail to include attributes 90 and 91 when a router hostname is used as the tunnel ID and when the tunnel ID is not included in the user profile.

There is no workaround.

CSCdw68658

The gateway will reject a mid-call Invite with hold sdp where the connection information (c line) is set to 0.0.0.0 and the port number of the media description (m line) is also set to 0. Instead of responding with a 200 OK response, the gateway will return a 488 Media Unacceptable response. The problem will not occur if the user agent placing the gateway on hold, sets the port number to a value other than 0.

There is no workaround.

CSCdw77524

When rtp payload-type cisco-codec-fax-ind is changed from 96 to 99 then we ingress an invite with sdp rtp payload type 96 nte the gateway responds with an rtp payload type 97.

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(2)XB4. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdr47232

Set operation is not implemented for a few dsx1 specific MIB objects like dsx1LineType, dsx1LineCoding etc.

CSCdr85436

Description: This command can be used in the global config mode, to enable sending radius attribute 32 (NAS-Identifier) in the accounting request. By default fully qualified domain name (FQDN) is sent in the attribute when the format is not specified.

Syntax:

[no] radius-server attribute 32 include-in-accounting-req {format <A string that may 
have %i, %h or %d.>}
 
 %i = IP address
 %h = Hostname
 %d = Domain name
 

FQDN is sent by default if the format string is not configured.

Examples:

 manly(config)#radius-server attribute 32 include-in-accounting-req format cisco %h.%d %i

Following string will be sent in NAS-identifier as a part of accounting record.

cisco manly.nlab.cisco.com 10.0.1.67

A system accounting record needs to be sent when a radius server is added or deleted. This will be committed in latest 12.2 branch and will also be committed in latest 6400 branch.

There are no known workarounds.

CSCdu40402

On AS5400, AS5800, and AS5850 access servers running Cisco IOS version 12.2XB, executing the command show tdm mapping will not show resource s that are used for CAS calls.

There is no workaround.

CSCdu40615

Some clients may fail to successfully complete IP Control Protocol (IPCP) negotiations when thousands of PPP sessions are simultaneously reestablished, as is the case when an interface with many links is recycled. All Layer 2 Tunneling Protocol (L2TP) sessions are established, but some client virtual access interfaces may not get a negotiated IP address. The missing IP address results in lost IP connectivity on that link.

There is no workaround.

CSCdu64847

CISCO-AAA-SESSION-MIB user disconnect feature doesn't work for vpdn connections on the LNS.

CSCdu43689

Currently, the Per-User Request buffer is limited to 600 bytes. If the user profile has more than 600 bytes of configuration information, the Per-User attributes are not processed, which results in rejecting the user.

There is no workaround.

CSCdu67010

Some TACACS+ attribute string names and attribute string values have changed slightly, e.g. "nas_rx_speed" is now "nas-rx-speed". This may cause problems for backend accounting applications trying to process records or authorization failures.

CSCdu74728

No accounting records are generated for outbound Telnet sessions after connection accounting is configured.

There is no workaround.

CSCdu84692

When using 12.2(2.x) and 12.2(3.x)PI code, local VPDN authorization does not failover to the next method in the method list if the domain/dnis profile is not found. The workaround is to only use RADIUS/TACACS+ vpdn authorization.

CSCdu86243

The RADIUS attributes Ascend-Client-Primary-DNS and Ascend-Client-Secondary-DNS do not work in 12.2(3.4)T or later. The Cisco-AVPair ip:dns-server also does not work.

There is no workaround.

CSCdv01412

Conditions under which the problem occurs:

When A calls 300, no voice loopback occurs.

Symptoms of the problem: silent.

Workaround: There is no workaround.

CSCdv01555

Spurious access may been seen when TACACS+ is enabled in IOS versions 12.2(3.4)T or later.

There is no workaround.

CSCdv02732

A router that is running Cisco IOS Release 12.2(3.4) T or a later release may reload unexpectedly after the Terminal Access Controller Access Control System (TACACS+) command accounting is enabled and a config net privileged EXEC command is executed. There is no workaround.

CSCdv03076

A Cisco router running 12.2(3.4)T or later will not process Ascend RADIUS server attributes even if "non-standard" is part of the radius-server host configuration statement if the radius-server is referenced through a aaa server group. The workaround is not to use a server-group and use group radius instead.

CSCdv03689

If a Point to Point Protocol (PPP) Multilink bundle interface goes down while data is flowing through it, a Cisco router may reload.

There is no workaround.

CSCdv04999

The username, accounting record type, and service attributes in the command accounting record is do not have appropriate value.

There is no workaround.

CSCdv13634

AAA Accounting is not done for the additional links added to Multilink PPP bundle when "aaa accounting delay-start" is configured.

There is no workaround.

CSCdv19031

Currently with radius debugging turned on customers see a lot of debugs describing attributes in the packets sent and received. In order to reduce the amount of spewed out on the console a new option of 'brief' needs to be added the 'debug radius' command. This option will only indicate I/O transactions with some packet header information. Customers not turning on debugging or, not doing RADIUS wont see this problem.

CSCdv19928

When the Idle-Timeout attribute is received from RADIUS on an asynchronous interface, a vaccess interface is created and the timeout is not applied directly to the asynchronous interface. The Idle-Timeout attribute still works. The only side effect is that there is an extra vaccess created that is bound to the asynchronous interface.

There is no workaround.

CSCdv20977

Incoming Multilink Point-to-Point Protocol (MLP) packets from an ATM interface are getting process switched when a virtual template is used for the MLP bundle configuration.

CSCdv26709

Certain values for Ascend-Disconnect-Cause and Ascend-Connect-Progress are recorded inaccurately in Stop messages. This is mainly observed in 122T train.

This problem is observed with PPP sessions when using RADIUS Accounting.

There are no workaround.

CSCdv29468

If a PPP client does not authenticate after agreeing to do so during LCP negotiation, the PPP session will continue to stay open in this limbo state until the client disconnects the session.

CSCdv33270

Under certain conditions, resources may be associated with a virtual private dialup network (VPDN) group even when there are no active calls.

There is no workaround.

CSCdv33313

When network accounting is performed for PPP over ATM (PPPoA) sessions, RADIUS "start" or "stop" accounting records may occasionally fail to be sent. There is no workaround.

Under certain conditions on a LAC, if the session is a VPDN forwarded session and the connection to the LAC is a dedicated serial line, memory can be leaked because AAA misses the stop record, so it never cleans up the AAA data for the session. This will happen if the connection continuously tries to renegotiate then attempt forwarding, which never succeeds. Eventually, the client sends a TERMREQ which restarts the session, but AAA does not get a NET STOP event so memory is leaked.

CSCdv34768

A Cisco router running IOS may show the following traceback when using "local-case" authentication:

00:05:16: %AAA-3-BADMETHOD: Cannot process authentication method 2160756888

There is no known workaround.

CSCdv40116

Reverse-access Authorization fails if the method used is Radius. Radius mandatory attribute "port" is not properly obtained causing this authorization failure.

There is no work around.

CSCdv40729

In a plain bri-pri (Peer - NAS) scenario, when a call is disconnected with the command 'clear in serial0:23' on the NAS, the Ascend-Disconnect-Cause value generated is '0' (No-Reason).

When the call is brought down by clearing the interface on the peer, it is given a value(63). If brought down by doing 'shutdown' on peer/NAS value 11 is generated. The problem occurs only with by doing clear interface on the NAS.

CSCdv41871

Ping fails when non-mlppp call is up on B-channel previously used to terminate mlppp call.

CSCdv43136

We may see some unexpected debug information during call suspend. Those debug information doesn't cause any side effect beside displaying unexpected debug information.

CSCdv43856

aaa attr debug does not show the tag added. This is seen in 12.2(4.2)PI. This is just a problem in debug and will not affect any other functionality.

CSCdv54349

When running 12.2(5.2)T and later IOS images, you may be unable to do local AAA authentication. There is no workaround. Either do AAA to a remote server or downgrade to an earlier release of code.

CSCdv62649

The command ip tacacs source-interface doesn't work properly. If configured to use loopback interface for tacacs packets, router may still use interface address.

CSCdv64668

The first PAP authentication after a PPP renegotiation triggered by a CONFREQ from the client will fail even though the RADIUS/TACACS+ server returns a success.

There is no workaround.

CSCdv67009

The following error message may be seen on a Cisco voice gateway running the Session Initiation Protocol (SIP):

state 8 (STATE_DISCONNECTING) substate 0 (SUBSTATE_NONE)
 -Traceback= 60DAD08C 60DAD7AC 6040ACD4 6040ACC0.
 

This indicates that the call was cancelled while it was in the process of being brought up.

This message can be safely ignored.

Spurious memory access messages appear on gatekeepers when an URQ without a call signal address in it is sent to Gateway.

There is no work around.

CSCdv79210

A Cisco router gradually looses memory when Media Gateway Control Protocol (MGCP) calls are originated on the router.

There is no workaround.

CSCdv83040

When using Ascend RADIUS attribute 242, IP protocols of 50 and 51 will not be accepted. This will cause users with these IPsec protocols set in their profile to be disconnected.

CSCdv83402

A PPPoE/PPPoA aggregation router may unexpectedly reload when many PPP events happen in a short amount of time. The router will display a STACKLOW message before reloading.

CSCdv87754

Symptom: A Cisco AS5850 Route Switch Controller incorrectly attempts to repeatedly netboot a Cisco IOS image if it cannot find the specified boot system image on its compact flash. The system interprets the full path of the configured boot image that failed as the image it should netboot.

Messages similar to the following are observed:

 Sleeping for 2 secs before next netboot attempt
 %SYS-6-READ_BOOTFILE_FAIL: disk0:c5850-p9-mz File boot failed -- File not 
 accessible.

The correct behavior for a bootloader if it cannot find any specified boot images at reload time is to fall back and request the system to run the first image it can find off disk0: or bootflash:

Conditions: Cisco AS5850 Route Switch Controllers with Cisco IOS 12.2(2)XB1 or Cisco IOS 12.2(2)XB2 bootloaders may experience this problem at reload time if the boot system image configuration points to a file on disk0: that does not exist.

Workaround: Ensure that the boot system image configuration points to an existing and valid image on disk0:, provide additional correct boot image locations in the configuration, or use a bootloader of version Cisco IOS 12.1(5)XV3.

CSCdw00019

Although SGBP tunnels will still be up, SGBP bidding itself might stop working after a router has been up for sometime. This problem only occurs if two routers in the stack group receive two links of a bundle at the same time.

Removing, and reapplying the SGBP config was sufficient to get things working again.

CSCdw01726

A Simple Network Management Protocol version 3 (SNMPv3) user is created using message digest 5 (MD5) authentication using the following commands:

snmp group groupy v3 auth

snmp user abcdefghij groupy v3 auth md5 abcdefghij

An SNMP walk is performed, the configuration is saved, and the router is reloaded.

newhope:~/src/wccp2# snmpwalk -v 3 -u abcdefghij -A abcdefghij -a MD5 -l 
AuthNoPriv 194.12.224.11

It is working and a debug snmp header shows this:

Incoming SNMP packet
 : v3 packet         security model: v3       security level: auth
 username: abcdefghij

A second SNMP walk is performed:

newhope:~/src/wccp2# snmpwalk -v 3 -u abcdefghij -A abcdefghij -a MD5 -l 
 AuthNoPriv 194.12.224.11
 

After the second SNMP walk is performed, the command does not return any output and the debug snmp headers show this:

Incoming SNMP packet
 : v3 packet  security model: v3       security level: noauth
 : username: abcdefghij
 

There is no workaround.

CSCdw02945

Symptom: Incoming calls may fail to create a virtual profile even though the

router is configured for this.

Conditions: This problem may occur in a dial up environment where a virtual profile virtual template is defined but where no AAA authorization has been enabled This issue only occurs in 12.2 T.

Workaround: A workaround is to configure AAA authorization e.g., aaa authorization network default local

CSCdw06322

The following error message may be seen on a Cisco voice gateway running the Session Initiation Protocol (SIP):

This indicates that the call was cancelled while it was in the process of being brought up.

This message can be safely ignored.

CSCdw09542

Before this fix, per-user authorization required a service type of Outbound in the Radius profile.

CSCdw11765

PPP Link Control Protocol (LCP) is not accepting sent CONFACK negotiated on a asynchronous interface for a virtual profile.

There is no workaround.

CSCdw13432

When the called party is busy in a two-stage call scenario, the calling party may not hear a busy tone and the call terminates immediately. This behavior is observed with Cisco IOS Release 12.2(2)XB, Release 12.2(7), and some earlier 12.2 releases.

There is no workaround.

CSCdw18785

When a 302 redirect is received after a 18x with a COntact header the outgoing INVITE will have the request uri of the Contact in the 18x. It should use the Contact of the 302.

Workaround: Disabling rel1xx on the router.

CSCdw23836

When a 18x is received which was sent reliably, a PRACK needs to be sent. Subsequent 18x's received that match the previous one's call leg do not receive a PRACK. A workaround is to disable reliable provisional responses.

CSCdw25746

Symptom: Cisco Voice Gateways may experience a reload especially when running high levels of traffic.

Conditions: This problem may be experienced in 12.2(2)XB2 and 12.2 mainline releases.

Workaround: none

CSCdw28786

When the customer tries to use ^C to abort the copy operation when he prompted for confirmation, he can't break out of the copy process.

CSCdw30994

When downloading IP pools from a AAA server, there is no way to define a non-contiguous range of addresses using multiple statements like this:

"ip:pool-def#1=aol-pool 192.168.232.0 192.168.237.255",
 "ip:pool-def#2=aol-pool 192.168.238.1 192.168.238.160"
 

When those statements are applied, the second pool-def overwrites the first one. Defining the pools on the command line yields the expected result. This only happens in 12.2(2)XB ED release train. 12.1/12.2 does not exhibit this behavior.

CSCdw35046

A Cisco router may reload when proxied RADIUS is used for authentication and accounting.

There is no workaround.

CSCdw35930

The command aaa authentication attempts login <n> appears in the configuration if the command tacacs-server attempts <n> is present in the configuration. Changes to either command will be reflected in the other. Also, the number of attempts granted is actually one less than the number configured. The workaround is to configure one more attempt than the number you actually want.

CSCdw43862

For some devices that are not conforming to V.110 async to sync padding requirements, this cli command allow the users to disable the padding.

CSCdw46065

A Cisco router that is used as a gateway may reload if one of multiple record routes that are received on the gateway is invalid.

There is no workaround.

CSCdw53071

If a second call is made after the first call is completely disconnected (by hanging up the phone instead of using the flash feature to switch between two calls), the second call may fail.

There is no workaround.

CSCdw53243

In a Cisco Signaling System 7 (SS7) Interconnect for Voice Gateways solution, if a Cisco AS5400 universal access gateway receives an incoming time-division multiplexing (TDM) call (NI-2, PRI, channel-associated signaling [CAS]) with a called number that does not match a configured dial-peer, the call will be connected to a modem, and a modem tone will be played back to the calling party. This is normal behavior, however there is no configurable option for such to be rejected instead of being treated as a modem call.

CSCdw62969

A network access server (NAS) that is running Cisco IOS Release 12.2(02)XB3 or Release 12.2(8)T may reload when Layer 2 forwarding (L2F) virtual private dial-up network (VPDN) calls are placed using an authentication, authorization, and accounting (AAA) VPDN user profile that does not contain the RADIUS class (25) attribute.

Workaround: Configure a dummy RADIUS class (25) attribute in the VPDN user profile on the AAA server.

CSCdw66251

SIP gateway midcall INVITE requests in the called to calling party direction will have the Route header constructed incorrectly. ACK requests in the called to calling party direction will have the request URI constructed incorrectly. This could cause some operations such as T.38 fax relay to fail.

This problem can occur only if two or more SIP proxies are in the SIP signalling path and the Record Route feature is enabled.

There is no workaround.

CSCuk25642

When using callin authentication on a LSDO call with RADIUS, PPP sends multiple authorization requests to AAA. This will slow down call setup but have no functional impact.

CSCuk25721

RADIUS CLID attribute was missing for large scale dialout accounting.

CSCuk25947

If PPP authentication is configured on an interface and if a user negotiates a callback during a Link Control Protocol (LCP) operation, the call will fail if the user does not have any callback information configured.

There is no workaround.

CSCuk26562

AAA id debugging was not clear and displayed far too much information.

CSCuk26642

RADIUS calls with a non-RFC supported value were accepted when they should be rejected.
