Introduction

The CSG2 is an application that runs on the Cisco Service and Application Module for IP (Cisco SAMI), a high-speed processing module. The CSG2 provides content-aware billing, service control, traffic analysis, and data mining in a highly scalable, fault-tolerant package. The CSG2 provides the software required by mobile wireless operating companies and other billing, applications, and service customers.

The CSG2 runs on the Cisco SAMI, a new-generation high performance service module for the Cisco 7600 series router platforms. The CSG2 is typically located at the edge of a network in an Internet service provider (ISP) point of presence (POP), or Regional Data Center.

In a prepaid configuration that requires a billing plan from the quota server, if RADIUS Accounting Starts begin arriving at a rate that exceeds the capacity of the CSG2, the CSG2 might drop some of the responses from the quota server.

Workaround: Do not exceed the capacity of the CSG2.

CSCsr88505—CSG2 - Policy priority values greater than 511 should not be permitted

The CSG2 allows the configuration of priority values up to 65535 for policies within content rules. However, the underlying code only allows values up to 511. Configuring a priority higher than 511 results in the content rule matching only the default policy.

Workaround: Ensure that all priority values are set to 511 or lower.

CSCsx72588— CSG2: The ip csg entries user idle command with the pod keyword is required for POD to work

The Packet of Disconnect (POD) feature does not work at the billing plan level.

Workaround: Configure PoD at the global level by configuring the pod keyword on the ip csg entries user idle pod command in global configuration mode.

CSCsy57824—WAP 1.x AoC URL redirect fails with meter exclude mms wap

With the meter exclude mms wap command configured and AoC enabled on a service, when a subscriber tries to browse with WAP 1.x, the CSG2 consults the quota server with a content authorization request and the quota server then responds with a content authorization response with the action of redirect and the URL to be redirected to. the page does not load on the subscriber's cell phone.

Workaround: Disable the exclude mms option redirect command.

CSCsy57924—CSG2: Memory leak when removing RADIUS VSA configuration

If a large number of reporting RADIUS VSA subattributes are configured or unconfigured for the CSG2, a large number of messages like the following is generated:

0x4518DEAC 0000000272 0000000001 0000000272 CSG RADIUS VSA

Workaround: None.

CSCsz21796—Bad refcount possible on error from ssvc

If the CSG2 tries to send an HTTP redirect packet to a subscriber, the following error message might be generated:

%SYS-2-BADSHARE: Bad refcount function-name

Workaround: None.

CSCta70187—Content inactive until recreated; cannot bring content WAP-WAP2 inservice

If a change is made on the standby CSG2, and a content is taken out of service, the CSG2 might not be able to bring the content back inservice. The following error message is generated:

% Cannot bring content <*> inservice, content out of service in progress

Workaround: Remove and reapply the entire context configuration.

CSCta97199—Unexpected repetitions of service reauthorizations

When performing RADIUS reauthorization and time-based billing, the CSG2 might repeat.

Workaround: Enable the quota server to grant more than the remaining quota.

CSCtb37275—Stale virtual teletype session

Under certain conditions, a stale VTY could be created in the CSG2.

Workaround: None.

CSCtb71637—%CSG-3-KUT_CLEANUP_ERROR on CSG2

The CSG2 might generate continual error messages:

SAMI 1/8: Aug 30 14:05:33 AEST: %CSG-3-KUT_CLEANUP_ERROR: OPENMOBILEWEB, ip= 10.227.179.191, uid= 61425166227, (1/48/2822/9217), -Traceback= 0x4428BB68 0x45145678 0x451475CC 0x4514A2D0 0x4514A5D8 0x4513B158 0x450FBF6C 0x4524E69C 0x44F76AE8 0x44F948FC 0x44F97558 0x4507D9EC 0x44F624AC 0x44F624AC 0x4507DAA8 0x45081C10

SAMI 1/8: Aug 30 14:08:00 AEST: %CSG-3-KUT_CLEANUP_ERROR: OPENMOBILEWEB, ip= 10.228.102.132, uid= 61425170578, (1/48/2054/9217), -Traceback= 0x4428BB68 0x45145678 0x451475CC 0x4514A2D0 0x4514A5D8 0x4513B158 0x450FBF6C 0x4524E69C 0x44F76AE8 0x44F948FC 0x44F97558 0x4507D9EC 0x44F624AC 0x44F624AC 0x4507DAA8 0x44E6AEC4

Workaround: None.

CSCtf55741—CSG2 might not return recently-granted quota in a quota return

A prepaid charging gateway might report that the CSG2 is using more quota than is allowed.

Workaround: None.

CSCtg01115—L4Flow "Network Initiated" flag not set correctly in intermediate UDP stat CDR

For a network-initiated UDP flow that is part of an RTSP session, the L4Flow "Network Initiated" flag is set correctly in the final "UDP Stats" CDR, but not in any "Intermediate UDP Stats" CDRs. In the "Intermediate UDP Stats" CDR, the flag is always set to zero, even if the flow is network-initiated.

Workaround: None.

CSCtg70982—The secret RADIUS key specified with the ip csg radius endpoint command changes after each write memory operation

The secret RADIUS key for the endpoint that is displayed in the show run output changes as write memory operations are performed.

Workaround: None.

CSCtg90246—The PoD IP address is not assigned if the sticky user was created before the gateway sends the RADIUS Accounting Start message

If a user is created as a sticky user before the gateway sends the RADIUS Accounting Start message, the CSG2 fails to send the PoD or CoA for the user.

Workaround: None.

CSCth09467—CSG2: The Accounting session ID is not used for RADIUS correlation

The accounting session ID is not used for RADIUS correlation to stop the user. The output of the show user command does not show the user's Correlator attribute. The CP leaks fastblk memory allocated for the RADIUS Correlator attribute.

For this problem to occur, all of the following conditions must be met:

The ip csg radius correlation command must be configured.

The RADIUS Accounting Start message must have Cisco VSA subattributes, but not "user_session_correlator=", so that the Acct-Session-Id (RADIUS attribute 44) is used for correlation.

Workaround: Ensure that the gateway includes the "user_session_correlator=" Cisco VSA attributes.

CSCth23631—FTP CDR Error: NewLine character in UserName, FileString and FTPCommand TLVs

The CDRs for Layer 7 FTP parsing include a NewLine character (0d 0a) after UserName, FileString, and FTPCommand TLVs.

Workaround: None.

CSCty02688—CSG2: Improper session synchronization during upgrade

When performing an in-service upgrade and synchronizing sessions from the active CSG2 Release 4, or any earlier release, to the standby CSG2 Release 5, or any later release, the synchronization might not complete correctly. The standby CSG2 is synchronized with an unexpectedly huge number of IP bytes uploaded and downloaded for all sessions. When the standby CSG2 becomes active, it reports this huge number of uploaded and downloaded IP bytes to the BMA, causing all sessions to be overcharged.

Workaround: Do not perform an in-service upgrade from CSG2 Release 4, or any earlier release, to CSG2 Release 5, or any later release.

CSG2 Software for Cisco IOS Release 12.4(15)MD5 - Closed Caveats

The following list identifies Closed caveats in the CSG2 software for Cisco IOS Release 12.4(15)MD5:

CSCsh25384—CP crash in csg_gtp_queue_and_send when running simple_redund

If a failover occurs and the no ip csg bma or no ip csg quota-server command is issued, the CSG2 might crash.

CSCtf51779—CSG2 fails to bring content in service due to REGEX error

The CSG2 might fail to bring a content in service due to the following REGEX error:

REGEX: regexp length <n>, bigger than allowed maximum length 128

CSCti35812—Reload triggered when parsing POP3 packet

When the CSG2 is performing Layer 7 parsing of POP3 or SMTP e-mail traffic, and an e-mail packet is received with a crafted malformed, header, a watchdog might trigger a reload of the CSG2.

CSCtj04285—Slow clearing of the quota server queues in the CSG2

During high traffic conditions the CSG2 clears the quota server queue too slowly.

CSCtj73069—CSG2: Usage statistics are not replicated to redundant side during failover

The session usage statistics are not replicated to the standby CSG2.

CSCtj99945—CSG2: Improper quota server load balancing

The assignment of user entries to quota servers for load-balancing might be askew. For example, if 100 user entries were created with two active quota servers configured, the expected behavior is that each quota server would be assigned about 50 user entries. However, the number of user entries assigned to each quota server might actually be asymmetric and inconsistent.

CSCtk13449—Simultaneous crashes on active/standby at dllobj_lite_add

A simultaneous reset might occur of two CSG2s operating in redundant mode.

Cisco SAMI Software for Cisco IOS Release 12.4(15)MD5 - Open Caveats

The following list identifies Open caveats in the Cisco SAMI software that impact the CSG2 software for Cisco IOS Release 12.4(15)MD5:

CSCtk35711—CSG2 takes 5 minutes to detect iSCSI failure due to network outage

The CSG2 might take up to five minutes to detect an iSCSI failure resulting from a network outage.

For this problem to occur, all of the following conditions must be met:

The session timeout must be set to 50 seconds or greater.

The interface that the CSG2 uses to communicate with the iSCSI target must be down.

Workaround: Enter the following commands to enable the CSG2 to detect the failure after the session times out.

ip tcp mss 1460
ip tcp path-mtu-discovery

Cisco SAMI Software for Cisco IOS Release 12.4(15)MD5 - Closed Caveats

The following list identifies Closed caveats in the Cisco SAMI software that impact the CSG2 software for Cisco IOS Release 12.4(15)MD5:

CSCsz42882—File systems not cleaned up when iSCSI link goes down

With iSCSI link flaps, stale file systems remain in the system. Once the stale file descriptors reach the maximum supported limit, new file systems cannot be created and the iSCSI link fails to come up.

CSCta44366--iSCSI connection not getting initiated from the CSG2

If the CSG2 is rebooted, and the none of the configuration starts with ip csg, entering the ip csg iscsi profile command after the reboot does not initiate an iSCSI connection.

Cisco Product Security Incident Response Team (PSIRT) - Closed Caveats

The following list identifies Cisco PSIRT closed caveats that impact Cisco IOS Release 12.4(24)MD5:

CSCtd10712

The Cisco IOS Software network address translation (NAT) feature contains multiple denial of service (DoS) vulnerabilities in the translation of the following protocols:

CSG2 Software for Cisco IOS Release 12.4(15)MD4 - Open Caveats

The following list identifies Open caveats in the CSG2 software for Cisco IOS Release 12.4(15)MD4.

CSCsq05068—CSG2 R2: Prepaid RADIUS stress causes packet loss to the quota server

In a prepaid configuration that requires a billing plan from the quota server, if RADIUS Accounting Starts begin arriving at a rate that exceeds the capacity of the CSG2, the CSG2 might drop some of the responses from the quota server.

Workaround: Do not exceed the capacity of the CSG2.

CSCsx72588— CSG2: The ip csg entries user idle command with the pod keyword is required for POD to work

The Packet of Disconnect (POD) feature does not work at the billing plan level.

Workaround: Configure PoD at the global level by configuring the pod keyword on the ip csg entries user idle pod command in global configuration mode.

CSCsy57824—WAP 1.x AoC URL redirect fails with meter exclude mms wap

With the meter exclude mms wap command configured and AoC enabled on a service, when a subscriber tries to browse with WAP 1.x, the CSG2 consults the quota server with a content authorization request and the quota server then responds with a content authorization response with the action of redirect and the URL to be redirected to. the page does not load on the subscriber's cell phone.

Workaround: Disable the exclude mms option redirect command.

CSG2 Software for Cisco IOS Release 12.4(15)MD4 - Closed Caveats

The following list identifies Closed caveats in the CSG2 software for Cisco IOS Release 12.4(15)MD4.

CSCta46295—Image crashes when performing a ROLLBACK between two running configurations

If you attempt a ROLLBACK with a saved running configuration, using the config replace (disk):(file) command on the CP, the CSG2 might crash.

CSCtb70452—CSG2: Continuation TLV correlator might not be unique

If the data for a record does not fit in a single IP packet, the BMA or quota server might associate data from a Continue CDR with an incorrect BMA or quota server record. This can occur because the CSG2 generates a correlator value in the Continue TLV that might not be unique per CSG2.

CSCtc21701—Stale VTY session issue

Under certain conditions, a stale VTY could be created in the CSG2 which can be detected using the output of the show ip csg users command.

CSCtc76186—TCP sessions not closed to the server side

When both of the TCP peers decide to close a session, each peer must send its own FIN/ACK and then also ACK the FIN/ACK of the peer. The CSG2 appears to close the session before the last ACK exchange:

Instead of forwarding the last ACK from the client to the server, it sends an RST to the client.

Instead of forwarding the last ACK from the server to the client, it silently discards the last ACK.

After a while, the server side might run out of sockets.

CSCtd32600—RADIUS Accounting Start dropped

When the CSG2 is configured as a RADIUS proxy, it might not forward some RADIUS Accounting Start packets from the GGSN to the RADIUS server. The CSG2 drops the sessions due to a lack of response from the RADIUS server.

Cisco SAMI Software for Cisco IOS Release 12.4(15)MD4 - Open Caveats

There are no Open caveats in the Cisco SAMI software that impact the CSG2 software for Cisco IOS Release 12.4(15)MD4.

CSCsy65876—The show tech output is empty when debug information is written by the Cisco SAMI

Some debug information, such as the output from show tech and show sami config-mode commands, is missing from the debug information files in some or all of the PPCs of the Cisco SAMI that are generated prior to a reload, following a critical error.

This problem can occur when there is no active physical console connected to the PPC.

CSCsz86656—The Cisco SAMI is not setting the DBUS Trust bit to 1

The Cisco SAMI is not setting the DBUS trust bit to 1, which in turn causes the 7600 to re-mark the DSCP of the packets.

CSG2 Software for Cisco IOS Release 12.4(15)MD3 - Open Caveats

The following list identifies Open caveats in the CSG2 software for Cisco IOS Release 12.4(15)MD3.

CSCsq05068—CSG2 R2: Prepaid RADIUS stress causes packet loss to the quota server

In a prepaid configuration that requires a billing plan from the quota server, if RADIUS Accounting Starts begin arriving at a rate that exceeds the capacity of the CSG2, the CSG2 might drop some of the responses from the quota server.

Workaround: Do not exceed the capacity of the CSG2.

CSCsx72588— CSG2: The ip csg entries user idle command with the pod keyword is required for POD to work

The Packet of Disconnect (POD) feature does not work at the billing plan level.

Workaround: Configure PoD at the global level by configuring the pod keyword on the ip csg entries user idle pod command in global configuration mode.

CSCsy57824—WAP 1.x AoC URL redirect fails with meter exclude mms wap

With the meter exclude mms wap command configured and AoC enabled on a service, when a subscriber tries to browse with WAP 1.x, the CSG2 consults the quota server with a content authorization request and the quota server then responds with a content authorization response with the action of redirect and the URL to be redirected to. the page does not load on the subscriber's cell phone.

Workaround: Disable the exclude mms option redirect command.

CSCta46295—Image crashes when performing a ROLLBACK between two running configurations

If you attempt a ROLLBACK with a saved running configuration, using the config replace (disk):(file) command on the CP, the CSG2 might crash.

Workaround: None.

CSG2 Software for Cisco IOS Release 12.4(15)MD3 - Closed Caveats

The following list identifies Closed caveats in the CSG2 software for Cisco IOS Release 12.4(15)MD3.

CSCsj17103—CSG2: Timestamps in Service Stop Notify not consistent

The CSG2 might generate a CDR with a Connection timestamp that is one second earlier than the Service-Start timestamp.

CSCsl57813—CSG2: Some show commands do not honor term length break sequence

When entering CSG2 show commands that collect and display information from all of the CPUs in the CSG2, the output might not break or pause as expected based on the term length configuration. If that happens, long output can scroll off-screen unexpectedly.

This problem does not occur for information gathered from the CP, whether in a distributed command or otherwise.

CSCsq12202—CSG2: Downgraded HTTP traffic should match catchall policy if configured

When the CSG2 detects an HTTP protocol error, such as non-HTTP traffic hitting content that is configured with parse protocol http, it downgrades to Layer 4 inspection. The CSG2 allows all remaining traffic to pass through, and reports the traffic in the Unassigned Bytes TLV.

To be consistent with the CSG1, after downgrading to Layer 4 inspection the CSG2 should match the current transaction to the catchall policy in the content, if there is one configured. If no catchall policy is configured, then the CSG2 should use the block configuration in the content to determine whether to forward or block the traffic.

CSCsv83744—Failure to complete cold-bulk results in HA stall

If a spanning tree loop occurs in an HA network, a standby CSG2 might become stuck in COLD-BULK state for several hours.

CSCsv95317—R3: Possible configuration failure when using more than one console

If you use more than one virtual teletype terminal (VTY console) when interacting with the CSG2 (for example, using one VTY to enter show commands and another to enter configuration commands), one of the VTYs might hang and the CSG2 will not allow further configuration commands. The CSG2 issues the following message:

Config failed, CSG being configured by line

You must reboot the CSG2 before continuing.

CSCsx18737—The debug ip csg qs detail command might cause the CSG2 to crash when a Quota Push Request is received

The CSG2 might crash when the debug ip csg qs detail command is configured and a nonstandard Quota Push Request message is received.

CSCsx33049—Service Reauthorization Request (SRAR) sent as first request

If the ip csg quota-server retransmit command is set to 5 or lower, and a quota server fails over, the CSG2 might send a Service Reauthorization Request (SRAR) before sending a Service Authorization Request.

CSCsy41471—Speedup recovery of RADIUS packet drop due to buffer depletion

If the CSG2 depleted the RADIUS attribute pool while processing a large number of RADIUS requests at a very high rate, it might fail to proxy RADIUS requests to the RADIUS server, while the "radius attribute" and "radius deny" counters continue to increase.

CSCsy57839—CSG2: RADIUS debug can cause traceback and card reloading

If the CSG2 is configured for RADIUS endpoint or RADIUS proxy, and the debug ip csg radius command is entered, the CSG2 might reload.

CSCsy73456—The CSG2 might crash after Stack for process CSG BGCFG running low

The CSG2 might crash with the following messages in the crash information file:

SAMI 4/3: Mar 25 13:58:30.665 ISR: %SYS-6-STACKLOW: Stack for process CSG BGCFG running low, 0/24000

For this problem to occur, all of the following conditions must be met:

A large map must be configured.

The map must contain many match statements, wildcards, and Boolean operators.

The map must be changed and the content put back in service.

CSCsy85405—Crash in HTTP code when the records delay command is configured

The CSG2 might reload under certain conditions.

For this problem to occur, all of the following conditions must be met:

The data flow must match a CSG content configured with policies that require HTTP deep packet inspection (accounting type http).

The user must be a prepaid user.

The records delay command must be configured under the HTTP content.

A retransmitted pipelined request or response packet must result in temporary quota exhaustion and a subsequent service reauthorization request to the quota server.

The transaction must close before the response is received from the quota server.

CSCsy93255—CSG2 traceback when clearing user entries

Under certain RTSP load and stress conditions, some entries remain in the CSG2 User Table. Trying to clear this state results in a traceback.

CSCsz42035—CSG2: Quota Server bombarded with reauth requests for free service

For a prepaid subscriber with zero quota using a service with zero weight, the CSG2 might generate multiple reauthorization requests within a few seconds.

CSCsz59223—CSG2: Users on the standby CSG2 might be removed even though they are on the active CSG2

In a stateful redundant CSG2 configuration, the standby CSG2 User Table might not contain all of the subscribers that are present in the active CSG2 User Table.

This problem can occur if the standby CSG2 receives a RADIUS Accounting On or Off message from a GGSN, then receives a RADIUS Accounting Start message from the GGSN before completing processing of the RADIUS Accounting On or Off message.

This problem can also occur if the clear ip csg user command is entered.

CSCsz69398—Memory leak - Leakage of RADIUS attributes

The CSG2 might encounter a memory leakage that results in a malloc failure of RADIUS attributes and prevents the CSG2 from processing incoming RADIUS requests.

CSCta07579—R3.5 Traceback clearing user running WAP traffic

Doing Layer 7 WAP inspection, a KUT_CLEANUP_ERROR traceback is dumped to the console when the CSG2 attempts to remove a WAP user from the User Table. the user is not removed from the User Table.

CSCta21064—CSG2: HTTP might reserve and not charge or cancel reserved quota

If an HTTP packet consists of retransmitted bytes of a previous transaction, and new bytes of a new transaction, a service's "reserved", as displayed in the output of the show ip csg user all detail command, might keep incrementing.

CSCta39130—Byte reporting in resize TCP with RETX for multiple transactions

When a retransmitted packet has multiple transactions, the reported IP bytes for each transaction in that packet are incorrect.

CSCsl57813—CSG2: Some show commands do not honor term length break sequence

When entering CSG2 show commands that collect and display information from all of the CPUs in the CSG2, the output might not break or pause as expected based on the term length configuration. If that happens, long output can scroll off-screen unexpectedly.

This problem does not occur for information gathered from the CP, whether in a distributed command or otherwise.

Workaround: None.

CSCsq05068—CSG2 R2: Prepaid RADIUS stress causes packet loss to the quota server

In a prepaid configuration that requires a billing plan from the quota server, if RADIUS Accounting Starts begin arriving at a rate that exceeds the capacity of the CSG2, the CSG2 might drop some of the responses from the quota server.

Workaround: Do not exceed the capacity of the CSG2.

CSCsx72588— CSG2: The ip csg entries user idle command with the pod keyword is required for POD to work

The Packet of Disconnect (POD) feature does not work at the billing plan level.

Workaround: Configure PoD at the global level by configuring the pod keyword on the ip csg entries user idle pod command in global configuration mode.

CSCsy57824—WAP 1.x AoC URL redirect fails with meter exclude mms wap

With the meter exclude mms wap command configured and AoC enabled on a service, when a subscriber tries to browse with WAP 1.x, the CSG2 consults the quota server with a content authorization request and the quota server then responds with a content authorization response with the action of redirect and the URL to be redirected to. the page does not load on the subscriber's cell phone.

Workaround: Disable the exclude mms option redirect command.

CSCsk64158—Cisco IOS Software Multiple Features Crafted UDP Packet Vulnerability

Symptoms: Several features within Cisco IOS software are affected by a crafted UDP packet vulnerability. If any of the affected features are enabled, a successful attack will result in a blocked input queue on the inbound interface. Only crafted UDP packets destined for the device could result in the interface being blocked, transit traffic will not block the interface.

Cisco has released free software updates that address this vulnerability.

Workarounds that mitigate this vulnerability are available in the workarounds section of the advisory. This advisory is posted at the following link: http://www.cisco.com/warp/public/707/cisco-sa-20090325-udp.shtml.

Details on how to see if the affected feature is enabled on a device, is provided within the "Details" section of this advisory.

CSCsm27071—Cisco IOS Software Multiple Features IP Sockets Vulnerability

A vulnerability in the handling of IP sockets can cause devices to be vulnerable to a denial of service attack when any of several features of Cisco IOS software are enabled. A sequence of specially crafted TCP/IP packets could cause any of the following results:

The configured feature may stop accepting new connections or sessions.

The memory of the device may be consumed.

The device may experience prolonged high CPU utilization.

The device may reload. Cisco has released free software updates that address this vulnerability.

Workarounds that mitigate this vulnerability are available in the "workarounds" section of the advisory. The advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090325-ip.shtml

CSCsr29468—Cisco IOS Software Multiple Features Crafted TCP Sequence Vulnerability

Cisco IOS software contains a vulnerability in multiple features that could allow an attacker to cause a denial of service (DoS) condition on the affected device. A sequence of specially crafted TCP packets can cause the vulnerable device to reload.

Cisco has released free software updates that address this vulnerability.

Several mitigation strategies are outlined in the workarounds section of this advisory.

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090325-tcp.shtml

CSCsv04836

Multiple Cisco products are affected by denial of service (DoS) vulnerabilities that manipulate the state of Transmission Control Protocol (TCP) connections. By manipulating the state of a TCP connection, an attacker could force the TCP connection to remain in a long-lived state, possibly indefinitely. If enough TCP connections are forced into a long-lived or indefinite state, resources on a system under attack may be consumed, preventing new TCP connections from being accepted. In some cases, a system reboot may be necessary to recover normal system operation. To exploit these vulnerabilities, an attacker must be able to complete a TCP three-way handshake with a vulnerable system.

In addition to these vulnerabilities, Cisco Nexus 5000 devices contain a TCP DoS vulnerability that may result in a system crash. This additional vulnerability was found as a result of testing the TCP state manipulation vulnerabilities.

Cisco has released free software updates for download from the Cisco website that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available.

CSCsl57813—CSG2: Some show commands do not honor term length break sequence

When entering CSG2 show commands that collect and display information from all of the CPUs in the CSG2, the output might not break or pause as expected based on the term length configuration. If that happens, long output can scroll off-screen unexpectedly.

This problem does not occur for information gathered from the CP, whether in a distributed command or otherwise.

Workaround: None.

CSCsq05068—CSG2 R2: Prepaid RADIUS stress causes packet loss to the quota server

In a prepaid configuration that requires a billing plan from the quota server, if RADIUS Accounting Starts begin arriving at a rate that exceeds the capacity of the CSG2, the CSG2 might drop some of the responses from the quota server.

Workaround: Do not exceed the capacity of the CSG2.

CSG2 Software for Cisco IOS Release 12.4(15)MD1 - Closed Caveats

The following list identifies Closed caveats in the CSG2 software for Cisco IOS Release 12.4(15)MD1.

CSCso63210—CSG2 R2: Many users idling out of the CSG2 User Table degrades performance

If an idle timer is configured for the User Table, and if thousands of users idle out at the same time, the rate at which the CSG2 can handle incoming RADIUS messages is reduced.

CSCsq06947—CSG2: Unable to scale to 500K CSG2 User Table entries with 5 or more ip csg report radius attribute commands configured

When the CSG2 receives a higher-than-expected rate of RADIUS Accounting Starts with a large number of RADIUS attributes from the Network Access Server (NAS), it might deny the RADIUS requests because it cannot grow the buffer pool fast enough.

CSCsq17440—CSG2 R2: Incorrect request type used in RTSP AoC for interleaved

During Layer 7 inspection for RTSP, the quota server receives an incorrect content authorization request of type 0x08 (RTSP TCP). The request should be of type 0x09. The problem occurs when the RTSP session is transporting data over the control session (interleaved).

CSCsq25027—CSG2 R1: Incorrect service selected after removing configuration of billing plan

If you remove a configured billing plan or service using the no option (for example, no ip csg billing), and you then configure a new billing plan or service and assign it to a new transaction, the CSG2 might assign the wrong services to the transaction.

CSCsq31810—The CSG2 R2 HSRP stays disabled after group change

If the standby ip command is removed from a protected interface on the standby router, then reapplied, the reapplication fails, and output from the show standby command is empty.

For this problem to occur, one or more of the following conditions must be met:

The interface must be associated initially with a specific standby group. It must then be removed from that group, assigned to another group, then reassigned to the original group. For example:

interface gigabitEthernet 0/0.10
no standby 1 ip
standby 5 ip 10.10.30.105
no standby 5 ip
standby 1 ip

The standby version 2 command must be configured on the interface.

CSCsq52319—CSG2 memory is depleted when HTTP and SIP are configured on the same 1 GB Cisco SAMI

If both HTTP and SIP are configured on the same 1 GB Cisco SAMI, the CSG2's memory might be depleted. If this occurs, the CSG2 might deny incoming RADIUS requests.

CSCsq79149—CSG2 R2: Define New Units flag in Qualified TLVs for basis second transaction

TLVs that report units, such as the Qualified Usage TLV, might report a value of 1 (second) when basis second transaction is configured.

CSCsq90709—CSG2: The show ip csg user all command might not display some sticky user entries

The output from the show ip csg users all command might include some but not all of the sticky user entries.

CSCsr42444—The CSG2 does not allow user traffic in a VPN session in transparent mode

With a Cisco VPN client and a Cisco VPN concentrator, in a VPN session in IPSec transparent mode, no user traffic flows. The VPN connection is established, but traffic does not flow.

CSCsr43716—CSG2: RTSP crash due to URL fastblk memory corruption

While performing Layer 7 parsing of RTSP traffic, the CSG2 might crash if it receives a DESCRIBE message containing a URL that exceeds 512 bytes.

CSCsr45063—CSG2 - IMAP improperly handles token > 255 bytes

The CSG2 reloads with a crash indication.

The CSG2 might reload while performing L7 inspection of IMAP traffic if certain fields within the flow are >256 bytes.

CSCsr52175—Ping failure after excessive interface updates and error messages from IXP

If any combination of the following situations occurs:

Configuring thousands of exception dump commands with different addresses

Removing thousands of interfaces from the configuration

Thousands of HSRP state changes from ACTIVE to STANDBY on an interface

Then the following message might appear on the console:

%PLATFORM-1-DP_HM_FAIL: Failed to receive response from Fail to send message to IXP: Msgcode : %d
. Check `sami health-monitoring' configuration and see `show sami health-monitoring' for more info

Thereafter, although the interface might be UP on the CP, pings to the interface fail. Packets can be seen leaving the CSG2 from the interface, but data to the interface is not seen by the CP.

CSCsr57168—ServiceStop lost during quota server failure if User Table entry deleted

If multiple quota servers are active, and the user logs off during a quota server failover, the CSG2 might fail to generate a ServiceStop message. This might result in the user session not being billed correctly.

CSCsr93270—Year and month incorrect in BCD timestamps

If you configure the following commands:

records granularity service bytes 10240000 seconds 3600
ip csg records format fixed
 
   

Then CDRs for the service might report start and stop dates with years and months in the wrong format.

CSCsu03235—CSG2 - Redirection on zero quota grant not working with AoC enabled

If a service is configured for Advice of Charge, the CSG2 might fail to redirect a user when zero quota is received from the quota server in a Service Authorization Response.

CSCsu37742—Special SIP INVITE causing CSG2 to crash

CSG might crash when performing Layer 7 SIP inspection. The crash can occur while the CSG2 is parsing an incorrectly formed SIP INVITE request (that is, a SIP INVITE request in which the SDP portion of the message contains extra carriage return and line feed characters).

CSCsq38262—Sup32: PPCs fail to download the configuration unless the boot string is configured in the Supervisor

The Cisco SAMI processors fail to download the configuration from the Supervisor Engine. EOBC traffic does not work. The session from the Supervisor Engine to processors 1-8 does not work.

For this problem to occur, one or more of the following conditions must be true:

Supervisor Engine 32 must be used in the chassis without executing the boot eobc upgrade command.

LCP ROMMON version 121 must have been used at some time on the Cisco SAMI.

The Cisco SAMI must be moved from a Supervisor Engine 32 to a Supervisor Engine 720 or Route Switch Processor 720, or vice versa.

Booting via EOBC must be used with different version of the Supervisor Engine.

CSCsq47043—Standby crashes when re-configuring standby ip command

A router functioning as the standby for a Hot Standby Routing Protocol (HSRP) group might reload when it is dissociated from that group and then re-associated with it.

This problem does not occur for information gathered from the CP, whether in a distributed command or otherwise.

Workaround: None.

CSCso63210—CSG2 R2: Many users idling out of the CSG2 User Table degrades performance

If an idle timer is configured for the User Table, and if thousands of users idle out at the same time, the rate at which the CSG2 can handle incoming RADIUS messages is reduced.

Workaround: Either do not configure an idle timer for the User Table, or do not allow so many users to idle out of the User Table at the same time.

CSCsq05068—CSG2 R2: Prepaid RADIUS stress causes packet loss to the quota server

In a prepaid configuration that requires a billing plan from the quota server, if RADIUS Accounting Starts begin arriving at a rate that exceeds the capacity of the CSG2, the CSG2 might drop some of the responses from the quota server.

Workaround: Do not exceed the capacity of the CSG2.

CSCsq06947—CSG2: Unable to scale to 500K CSG2 User Table entries with 5 or more ip csg report radius attribute commands configured

When the CSG2 receives a higher-than-expected rate of RADIUS Accounting Starts with a large number of RADIUS attributes from the Network Access Server (NAS), it might deny the RADIUS requests because it cannot grow the buffer pool fast enough.

Workaround: None.

CSCsq17440—CSG2 R2: Incorrect request type used in RTSP AoC for interleaved

During Layer 7 inspection for RTSP, the quota server receives an incorrect content authorization request of type 0x08 (RTSP TCP). The request should be of type 0x09. The problem occurs when the RTSP session is transporting data over the control session (interleaved).

Workaround: Disable the AoC feature for RTSP traffic.

CSCsq25027—CSG2 R1: Incorrect service selected after removing configuration of billing plan

If you remove a configured billing plan or service using the no option (for example, no ip csg billing), and you then configure a new billing plan or service and assign it to a new transaction, the CSG2 might assign the wrong services to the transaction.

Workaround: Save the running configuration and force a reload of the CSG2.

CSCsq31810—The CSG2 R2 HSRP stays disabled after group change

If the standby ip command is removed from a protected interface on the standby router, then reapplied, the reapplication fails, and output from the show standby command is empty.

For this problem to occur, one or more of the following conditions must be met:

The interface must be associated initially with a specific standby group. It must then be removed from that group, assigned to another group, then reassigned to the original group. For example:

interface gigabitEthernet 0/0.10
no standby 1 ip
standby 5 ip 10.10.30.105
no standby 5 ip
standby 1 ip

The standby version 2 command must be configured on the interface.

Workaround: Save the running configuration and force a reload of the standby router.

CSCsq52319—CSG2 memory is depleted when HTTP and SIP are configured on the same 1 GB Cisco SAMI

If both HTTP and SIP are configured on the same 1 GB Cisco SAMI, the CSG2's memory might be depleted. If this occurs, the CSG2 might deny incoming RADIUS requests.

Workaround: Do not configure HTTP and SIP on the same board at the same time.

CSG2 Software for Cisco IOS Release 12.4(15)MD - Closed Caveats

The following list identifies Closed caveats in the CSG2 software for Cisco IOS Release 12.4(15)MD.

CSCsj16263—New connections denied during high traffic spike

Attempts to establish new connections through the CSG2 fail, particularly when traffic first starts to flow through the CSG2 at high volume. During this period, deep IPC queues are often observed on one or more of the CSG2 processors. Load management might show denied sessions.

For this problem to occur, the following conditions must all be true:

There must be very high rates of transactions or session establishment (greater than the specified rates).

There must be a rapid change in traffic conditions from low to a rate exceeding the specified capacity.

CSCsj33130—The CSG2 cannot boot up with a very large configuration

With configurations that include very large numbers of inservice contents that refer to policies with URL maps, the CSG2 can take more than 15 minutes to boot up, causing the CSG2 to be reset. This can result in a rebooting loop in which the CSG2 never fully enters service. This problem does not occur if the contents are not inservice when the CSG2 is rebooted.

CSCsl02342—Tariff switch not reporting all required TLVs in messages to BMA

If the quota server is configured to provide a tariff-switch time to the CSG2 in a SvcAuthResponse, the CSG2 does not report the tariff-switch TLV to the BMA.

CSCsm32575—R1: Crash if CDR format is changed from variable to fixed with traffic

The CSG2 might crash if the report format is changed from variable to fixed while running HTTP or RTSP traffic.

CSCsm34572—CSG2:R1- WAP aborts not sent for no quota and next-hop configuration

If WAP 1 content is configured with a next-hop address, the user has no quota at the start of a transaction, and WAP redirect is not configured, the transaction is not terminated with an abort.

If the user runs out of quota during a transaction, the transaction is not terminated with aborts to both the client and server, regardless of whether WAP redirect is configured.

CSCsm35164—CSG2 R1 Tiny window during bootup where CDRs might use internal clock time

If the CSG2 generates a CDR immediately after reloading, the value of the Start Time in the Timestamp TLV might be incorrect. Typically, the invalid value corresponds to a date in the year 2002.

This problem can occur if the CDR is generated before a value for the clock is received from the Supervisor Engine on a CSG2 Traffic Processor.

Since a clock value is usually received from the Supervisor Engine module shortly after bootup, the probability of this problem occurring is very small. Furthermore, deployment of CSG2s in a redundant configuration greatly reduces the probability of this problem occurring, because the redundant CSG2s receive a clock from the Supervisor Engine module before becoming active (and even before HSRP negotiation has completed).

CSCsm60821—CSG2: CDRs are generated on policy without accounting

The CSG2 might generate CDRs even when it is configured not to by disabling accounting under the CSG policy.

CSCsm84321—Quota server traffic stalls if no ip csg quota-server reassign is configured and the quota server fails

If no ip csg quota-server reassign is configured and the traffic to all quota servers stalls while one or more quota servers reports FAILED or flaps from FAILED to ACTIVE to FAILED, no quota server messages can get through and the CSG2 prevents prepaid traffic from flowing.

Cisco SAMI Software for Cisco IOS Release 12.4(15)MD - Open Caveats

The following list identifies Open caveats in the Cisco SAMI software that impact the CSG2 software for Cisco IOS Release 12.4(15)MD.

CSCsq38262—Sup32: PPCs fail to download the configuration unless the boot string is configured in the Supervisor

The Cisco SAMI processors fail to download the configuration from the Supervisor Engine. EOBC traffic does not work. The session from the Supervisor Engine to processors 1-8 does not work.

For this problem to occur, one or more of the following conditions must be true:

Supervisor Engine 32 must be used in the chassis without executing the boot eobc upgrade command.

LCP ROMMON version 121 must have been used at some time on the Cisco SAMI.

The Cisco SAMI must be moved from a Supervisor Engine 32 to a Supervisor Engine 720 or Route Switch Processor 720, or vice versa.

Booting via EOBC must be used with different version of the Supervisor Engine.

Workaround: If you move the Cisco SAMI from a Supervisor Engine 32 to a Supervisor Engine 720 or Route Switch Processor 720, or vice versa, use the following procedure to avoid this problem:

a. Configure the boot string on the Supervisor Engine:

Sup(config)# boot device module sami-slot disk0:sami image

b. Reset the Cisco SAMI to boot normally.

If the Cisco SAMI has a usable image on its compact flash, enter the following command:

Sup(config)# hw-module module sami-slot reset

Otherwise, boot the Cisco SAMI through the Ethernet Out-of-Band Channel (EOBC) from the Supervisor Engine by entering the following commands:

Sup(config)# boot device module sami-slot disk0:sami image

Sup(config)# hw-module module sami-slot boot eobc

Sup(config)# hw-module module sami-slot reset

c. After the Cisco SAMI comes up, ensure that the image is stored on the Cisco SAMI and automatically comes back up after a reboot by entering the following command:

Sup(config)# upgrade hw-module slot sami-slot software disk0:sami image

d. Remove the Cisco SAMI boot string configuration from the Supervisor Engine by entering the following command:

Sup(config)# no boot device module sami-slot disk0:sami image

Cisco SAMI Software for Cisco IOS Release 12.4(15)MD - Closed Caveats

The following list identifies Closed caveats in the Cisco SAMI software that impact the CSG2 software for Cisco IOS Release 12.4(15)MD.

CSCsg94209—The show command on a CPU3-8 redirected to the Supervisor Engine produces a 0-byte file

From processor 3-8, a pipe redirect when using rcp to the Supervisor Engine can result in errors, or can cause the processor to reload. For example, the following command might result in a 0-byte file:

Router-3> sh tech | redirect rcp://127.0.0.81/shtech
 
   

CSCsj09391—No error messages on the CP when IXP runs out of destination filters

When the Cisco SAMI/CSG2 runs out of destination filters, a new IP address configuration might not be effective even though it is accepted, and no error message is issued when the IP address is configured.

To verify that the Cisco SAMI/CSG2 has run out of destination filters, enter the show sami ixp statistics command after applying an IP address. If the Out of filter elements counter is not zero, and if it increments as a result of configuring the IP address, then the Network Processor destination filter limit has been reached.

CSCsj17733—Values for entPhysicalFirmwareRev and entPhysicalSoftwareRev are not shown

The ENTITY-MIB entries entPhysicalFirmwareRev and entPhysicalSoftwareRev do not return any values from the Cisco SAMI processor.
