Supported Hardware

Cisco IOS Release 12.2(8)BY2 supports the following Cisco 7000 platforms:

Cisco 7200 series routers (including the Cisco 7202, Cisco 7204, and Cisco 7206)

Cisco 7200 VXR routers (including the Cisco 7204VXR and Cisco 7206VXR)

For detailed descriptions of the new hardware features, see the "New and Changed Information" section.

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(8)BY2:

Router> show version
Cisco Internetwork Operating System Software
IOS (tm) 7200 Software (c7200-c6is-mz), Version 12.2(8)BY2, 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(8)BY2 supports the same feature sets as Cisco IOS Release 12.2, but Cisco IOS Release 12.2(8)BY2 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 4 lists the feature and feature set supported by the Cisco 7200 series routers in Cisco IOS Release 12.2(8)BY2.

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, (8)BY means a feature was introduced in 12.2(8)BY. 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.

Open Caveats—Cisco IOS Release 12.2(8)BY2

This section documents possible unexpected behavior by Cisco IOS Release 12.2(8)BY2 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdv63387

PDSN drops packets at moderate traffic conditions, and hence NDR throughput is very low when compared with the Max.throughput. This degradation is observed when AHDLC fragmentation is configured on the PCF.

There are no known workarounds.

Resolved Caveats—Cisco IOS Release 12.2(8)BY2

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(8)BY2. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdx86482

Point-to-Point Tunneling Protocol (PPTP) tunneling may not function, and data sent by a PPTP network server (PNS) may have invalid PPTP headers.

This symptom is observed after a virtual private dial-up network (VPDN) session comes up.

There are no known workarounds.

CSCdy34961

Spurious memory access made at vpdn_sss_perform_dynamic_bind. This occurs on a c7200 router while testing PPTP with SSS.

There are no known workarounds.

CSCdz04509

On a c7200 running Cisco IOS 12.2B-based PDSN, the object cCdmaPppRenegConnectionsAborted may not increment if the foll. scenarios of aborted PPP calls occur:

1. A TERMREQ received during PPP renegotiation

2. A RRQ with Lifetime=0 received during PPP renegotiation

The problem has been fixed in 12.2(8)BY2 release.

There are no known workarounds.

CSCdz19118

When ping is made over MIP flow with reverse tunnel and compression, downstream packets to MN are dropped at PDSN.

Workaround: Disable CEF and ping goes through over the flow.

CSCdz21896

When PDSN is configured under Controller-Member architecture While opening sessions the member might crash.

The PDSN might crash only when it is configured as a member under Controller-Member clustering.

Workaround: Do not configure the PDSN as a member under Controller-Member clustering.

CSCdz23611

For MIP with header compression and CEF enabled, the compression counters are incorrect when TCP packets are sent over the MIP flow.

Workaround: Disable CEF and the header compression counters are working fine.

CSCdz32147

While opening and closing MOIP sessions using 6500 mwam pdsn, HA is reloaded when "show ip mobile tunnel" command is issued.

There are no known workarounds.

CSCdz38529

Accounting for VPDN sessions is excluding the PPP STATION (FF03) bytes from packets to PDSN and packets from LNS to PDSN.

PDSN is not accounting the PPP STATION bytes (2 bytes) in packets received from Mobile and Packets received from the LNS.

There are no known workarounds.

CSCin06371

The SNMP query to cssgStatsObjects object-group return zero for the objects listed below:

cssgStatsLoginAttempts
cssgStatsLoginsSuccessful
cssgStatsActiveSessions
cssgStatsActiveHosts
cssgStatsActiveServices
cssgStatsPODs

The above mentioned problem can be noticed under all conditions as the feature has not been implemented yet.

The problem has been fixed and code was committed to c6400_pi7, ssg_oxygen_pi branches.

There are no known workarounds.

CSCin22974

On a c7200 running Cisco IOS 12.2B-based PDSN, when a PPP negotiation fails due to LCP timeout, cCdmaPppLcpFailures counters don't get incremented.

The problem has been fixed in 12.2(8)BY2 release.

There are no known workarounds.

CSCin23552

On a c7200 running Cisco IOS 12.2B-based PDSN, when a PPP session, for Simple IP service, comes up without IP address, neither the cCdmaPppConnectionSuccesses nor cCdmaPppConnectionFailures counter get incremented.

On the completion IPCP negotiation, if one of Service Selection Criterias is not met, RP and PPP sessions tear down. In this scenario, neither the cCdmaPppConnectionSuccesses nor cCdmaPppConnectionFailures counter won't get incremented.

The problem has been fixed in 12.2(8)BY2 release. The fix counts the PPP session as successfully negotiated as the actual failure is that one of the Service Selection Criterias (explained in PDSN PFS, Section 10) is not met.

There are no known workarounds.

CSCin23557

On a c7200 running Cisco IOS 12.2B-based PDSN, when a PPP negotiation fails during IPCP phase because of IP address shortage, the cCdmaPppIpcpFailures counter doesn't get incremented.

This condition occurs on virtual-template, the "ppp ipcp address required" option is configured.

When the above command is configured, if IP address shortage happens, PPP will get terminated.

The problem has been fixed in 12.2(8)BY2 release.

There are no known workarounds.

CSCin23921

The accounting for VSA attributes Acct-Input-Octets, Acct-Output-Octets, Acct-Input-Packets and Acct-Output-Packets is incorrect between 2 accounting stops. The packets/bytes are counted only between the last accounting start and accounting stop. The packets/bytes between last accounting stop and accounting start is not counted.

Mobile moves to dormant state and data is pumped during that time. When the mobile moves to active state, the number of packets accounted are between the last accounting start and accounting stop, instead of between 2 accounting stops.

There are no known workarounds.

CSCin24256

In CISCO PDSN, in some scenarios the visitor is getting deleted without decrementing the visitor count of FA. So, the visitor count will be more than the active vistors.

There are no known workarounds.

CSCin25669

After the execution of the config command for resizing the failure-history table, cCdmaFailHistInfo table becomes empty:

cdma pdsn failure-history <table-size>

There are no known workarounds.

Open Caveats—Cisco IOS Release 12.2(8)BY1

This section documents possible unexpected behavior by Cisco IOS Release 12.2(8)BY1 and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdv75504

When a Mobile IP session is opened, and packets are sent through the tunnel, the show interface tunnel X accounting command (on the Mobile IP tunnel) does not show any protocol based accounting information.

There are no known workarounds.

CSCdv75045

Occasional packet drops occur when a downstream sweep ping is executed, and when there are more than 8000 Mobile IP sessions hosted on the PDSN.

There are no known workarounds.

CSCdx03945

Adding hex strings that are exactly 31 bytes in length to the following directive will incorrectly set the key value:

ip mobile secure host 10.0.0.1 spi 100 key hex 1234567890123456789012345678901

A workaround is to make sure the value is exactly 32 bytes in length.

CSCdx55143

On the Cisco PDSN, a quota request is sent for a non-prepaid user if it is opened on a prepaid session. A quota request should not be sent for a non-prepaid user if the user registers over an already existing session that has an active prepaid flow.

A workaround is to register the non-prepaid user over a new session.

CSCdx60192

If IP fragmentation is enabled on the PCF, and AHDLC fragment size is greater than this value, then packets from the MN with an AHDLC fragment size that is less than the MTU configured on the PCF will be processed in the fastpath in the PDSN. This will cause AHDLC FCS errors.

A workaround is to remove any IP fragmentation on the PCF unless it is absolutely necessary.

CSCdx74938

After opening 10,000 Simple IP sessions, and PPP renegotiation is initiated, those sessions will go down.

There are no known workarounds.

CSCdx80222

On the Cisco PDSN, a MobileIP flow will not come up if IPCP renegotiation is initiated by a MN after the session is up.

There are no known workarounds.

CSCdy14130

PDSN reloads when you simultaneously close compression sessions and issue the show compress detail-ccp command.

As a workaround, do not issue show compress detail-ccp command while closing compression sessions.

CSCdy19930

On the Cisco PDSN, malloc failures are observed (with periodic accounting update 1), while mobiles connect and disconnect simultaneously.

A workaround is to disable periodic accounting update 1, or enter much higher values of periodic accounting intervals.

CSCdy75288

PPP data packets received at the PDSN from the mobile get switched to the Pi interface, even if the flow for the corresponding mobile is not yet created. This causes them to remain unaccounted for.

This problem happens only when the RP session has been established between the PCF and the PDSN, and an ahdlc channel has been allocated to the mobile. Thus, it occurs only for a short period of time before the flow gets created, or the flow fails to get established.

There are no known workarounds.

CSCdy85867

When 20000 sessions are open and PPP is renegotiated over them at a high rate—and you then close down of the sessions—a few sessions on the PDSN do not get closed successfully. Apparently, IPCP is continuously trying to send out Config Request packets, and these packets never go out of the box.

There are no known workarounds.

CSCdy88090

On the PDSN, the clear cdma pdsn statistics command may not clear the AHDLC related statistics.

There are no known workarounds.

CSCdz00743

On the PDSN, the following MIB objects may return NULL values, even though the corresponding service type flow actually fails to come up when underlying PPP session is UP.

cCdmaFlowSimpleIpFailures

cCdmaFlowMobilIpFailures

cCdmaFlowProxyIpFailures

cCdmaFlowVpdnFailures

There are no known workarounds.

CSCdz03252

On the PDSN, the following MIB objects may not increment even though I/O memory is locked up, and malloc failures appear.

cCdmaAhdlcMemDropPktsDec

cCdmaAhdlcMemDropPktsEnc

There are no known workarounds.

CSCdz12036

Running a Cisco PDSN at stress conditions causes sessions flapping; additionally, the PPP renegotiation success and failure counters do not tally with the total renegotiation counter.

There is no work around; however, this condition only occurs during stress conditions.

CSCin10386

While opening 8000 sessions with one Mobile IP flow each, the MobileIp flows count occasionally becomes greater than the session count.

There are no known workarounds.

CSCin19975

On the PDSN, PPP renegotiation may not be initiated by the PDSN during the second PDSN-to-PDSN handoff when the mobile moves between the same PDSNs.

There are no known workarounds.

CSCin22446

After disabling the ip route-cache (no ip route-cache), and enabling it again

with the ip route-cache cef command on the PDSN virtual-template, the CEF is not enabled on the vaccess.

There are no known workarounds.

Resolved Caveats—Cisco IOS Release 12.2(8)BY1

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(8)BY1. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdw60630

When a dormant handoff takes place on the PDSN, the PDSN does not send Release Indicator (F13 Accounting Attribute) to the radius server. This problem only occurs when the cdma pdsn accounting send start-stop command is configured on the PDSN.

As a workaround, for dormant handoffs, do not configure the cdma pdsn accounting send start-stop command.

CSCdx90388

Opening Mobile IP sessions at a high rate (>50cps) can cause a session to become stuck in opening state.

The workaround is to use a lower call setup rate when opening Mobile IP sessions (~20cps).

CSCdy08833

After opening of Mobile IP sessions, BADSHARE Tracebacks were observed while reloading the PDSN.

There are no known workarounds.

CSCdy11322

When precloning is configured, and the PDSN generates a proxy MIP request, that request fails if compression attributes are returned from AAA.

A workaround is to disable the configuration for precloning.

CSCdy24978

On the Cisco PDSN, at high call setup rates (greater than 150 cps), the cluster may drop new calls. Adding more members to the cluster does not improve the call setup rates linearly.

There is no workaround

CSCdy35759

When opening and closing PDSN sessions, the PPP CHAP attempts and success counters may not match in the output of the show cdma pdsn statistics command.

There are no known workarounds.

CSCdy37069

On a router equipped with a hardware compression component, the PDSN reloads when "compress stac" is configured (instead of "compress stac software") on a PDSN virtual template interface, and there is no user session utilizing that virtual template.

As a workaround, do not configure PPP hardware payload compression on a virtual template interface when the virtual template is to be used for PDSN CDMA. If compression is needed on a virtual interface, use any of the following.

a. specify software compression in the configuration command, or

b. establish a user session before configuring compression, or

c. remove the compression hardware from the router.

CSCdy40189

The Cluster Controller sends two cCdmaClusterMemberStatusChange traps when the PDSN member status changes.

There is no workaround because the problem could not be reproduced.

CSCdy43978

Malloc failures are observed while sending UP stream fragmented traffic through 20,000 Mobile IP Sessions. These failures are due to high packet rate; memory is recovered once the traffic is stopped.

A workaround is to set the maximum sessions on the PDSN to 8000.

CSCdz00198

A Cisco 7200 router that is running 12.2.1a.XC version of the PDSN solution, frequently reloads. This bug is a duplicate of CSCdw50718.

There are no known workarounds.

CSCdz05272

While displaying show aaa sessions, the PDSN crashed and auto-reloaded.

This bug is a duplicate of CSCdu58983.

There are no known workarounds.

CSCin15071

The SNMP query on the cCdmaAffectedAddress object on the PDSN cluster member returns a null string.

There is no workaround because the problem could not be reproduced.

CSCin15149

During mobile poweroff, before IPCP is up, the proxy registration entry is not getting deleted. At this point the user cannot perform proxy registration again.

A workaround is to delete the proxy registration, allowing the proxy flow to be opened.

CSCin16292

In a Cisco PDSN, the following MIB variables will return incorrect values:

cmiSecAlgorithmType and cmiSecAlgorithmMode will not support HMAC configurations, and will only return a value of "Other" (1).

faVisitorRegIDHigh variable may show negative values.

maAdvConfigTable will not return all the Vaccess details.

The following two variables are not supported, and will always return a "FALSE" value.

faIsBusy

faRegistrationRequired

There are no known workarounds.

CSCin18138

Some of the PPP Setup, RP Registration, Session failure and Clustering-related MIB counters may not return correct values on snmp query.

There are no known workarounds.

Open Caveats—Cisco IOS Release 12.2(8)BY

This section documents possible unexpected behavior by Cisco IOS Release 12.2(8)BY and describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdv75045

Occasional packet drops are observed when downstream sweep ping is executed, when there are 8000 MoIP sessions hosted on the SW AHDLC engine.

There are no known workarounds.

CSCdx03945

Do not add hex strings that are exactly 31 bytes in length to the following directive:

ip mobile secure host 10.0.0.1 spi 100 key hex 1234567890123456789012345678901

This will incorrectly set the key value. Make sure the value is *exactly* 32 bytes in length.

There are no known workarounds.

CSCdx55143

Quota request should not be sent for a non-prepaid user if the user registers over an already existing session which has a prepaid flow active.

Workaround: Register the non-prepaid user over a new session.

CSCdx60192

When using Cisco PDSN image, if IP fragmentation is enabled on the PCF, and AHDLC fragment size is greater than this, then packets from the MN with AHDLC fragment size lesser than the MTU configured on the PCF will be processed in the fastpath in the PDSN, and this will cause AHDLC FCS errors.

Workaround: Remove any IP fragmentation on the PCF unless absolutely necessary.

CSCdx80222

MobileIP flow will not come up, if IPCP renegotiation is initiated by MN after the session is up.

There are no known workarounds.

CSCdx90388

While opening MOIP sessions, one session got stuck in opening state. Opening MOIP sessions at a high rate (>50cps)caused one session to become stuck in opening state. The MoIP registration packet may be lost for any reason which will cause this problem.

Workaround: Use a lower call setup rate when opening MOIP sessions (~20cps)

CSCdy08833

BADSHARE Tracebacks observed while reloading PDSN. This occurs while reloading after creating MOIP Sessions

There are no known workarounds.

CSCdy11322

When precloned virtual-access interfaces are used, the type of the virtual access may not be set correctly. This can cause various problems from the output of the show int virtual-access not showing how the virtual-access is being used to functional problems for PDSN.

When PDSN generates a proxy MIP request, that request fails if compression attributes are returned from AAA and precloning is configured.

Workaround: Deconfigure precloning.

CSCdy14130

PDSN unexpectedly reloads when we close compression sessions and issue the show compress detail-ccp command at the same time.

Workaround: Do not issue the show compress detail-ccp command while closing compression sessions.

CSCdy19930

Malloc failures observed with periodic accounting update 1, while Mobiles connect and disconnect simultaneously.

The following conditions are known to cause this problem:

Open and close 2000 MOIP and 2000 SIP Sessions. Active time for each session is 120 sec, and inactive time is 180 seconds.

Set Periodic accounting update as 1

Repeat the above test 10 times.

Malloc failures observed on PDSN

Workaround: Disable Periodic accounting update 1

Alternative workaround: Use much higher values of periodic accounting intervals.

CSCdy23819

Using private addresses A and B, if we register two MNs, one with care-of address as A, and its home address as B and the other with care-of address as B, and its home address as A, then the HA crashes when processing the second registration.

Workaround: Since this is possible only when both the MNs and the PDSNs are in the same, one workaround is to use only public care-of addresses in both the PDSNs.

CSCdy24978

At high call setup rates (greater than 150 cps), the cluster may drop new calls.

Call setup rate seen with the addition of more members to the cluster does not improve linearly. At call rates higher than 150 cps per cluster, the cluster exhibits call drops.

There are no known workarounds.

CSCdy35759

When opening and closing PDSN sessions, the PPP CHAP attempts and success counters may not match in the output of the show cdma pdsn statistics command.

There are no workarounds.

CSCin10386

While Opening 8000 sessions with one mobileIP flow each, sometimes the mobileIp flows count becomes greater than session count.

There are no known workarounds.

CSCin15149

During poweroff close before IPCP up, the proxy registration entry is not getting deleted. So, the user cannot perform proxy registration again.

Workaround: Delete the proxy registration, then proxy flow can be opened.

CSCin16292

In a Cisco 12.2B based PDSN, the following MIB variables will return incorrect values:

cmiSecAlgorithmType and cmiSecAlgorithmMode will not support HMAC configs. It will return only value as Other(1).

faVisitorRegIDHigh variable may show values in Negative.

faIsBusy

faRegistrationRequired. The above two variables are not supported and will always return as FALSE.

maAdvConfigTable will not return all the Vaccess details.

There are no known workarounds.

Resolved Caveats—Cisco IOS Release 12.2(8)BY

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(8)BY. This section describes only severity 1 and 2 caveats and select severity 3 caveats.

CSCdy40097

The Cisco PDSN drops packets which are compressed with TCP header compression, Address Control Field Compression (ACFC), and Protocol Field Compression (PFC).

Workaround: Disable one of these compression schemes

Alternative workaround: Configure no ip route-cache on the virtual template, and no ip cef in the global configuration.
