Introduction

The Cisco ISR 3303 (Integrated SONET/SDH Router) is a high-density access platform with full SONET interoperability that enables service providers to deliver a single integrated solution with both voice services based on time-division multiplexing (TDM) and IP services.

The Cisco ISR 3303 dramatically reduces cost of ownership by enabling service providers to deliver TDM and data services on a single platform over SONET/SDH (synchronous optical network/synchronous digital hierarchy) optical fiber networks.

The Cisco ISR 3303 integrates SONET Add-Drop Multiplexor (ADM) capabilities and is a highly fault-tolerant service delivery platform connecting to SONET unidirectional path switched rings (UPSR) in local and metropolitan access networks. The Cisco ISR 3303 provides extensive facility and equipment protection for high network availability. From deployed services, the Cisco ISR 3303 provides eight clear-channel DS1 TDM service delivery channels, and eight 10-Mbps IP service delivery channels using the Ethernet medium.

The Cisco ISR 3303 is designed to use static and policy routing for most of its applications. Release 11.3(4)HA3 makes Cisco IOS IP and bridging functionality available on the Cisco ISR 3303.

For the Cisco ISR 3303, Cisco also offers optional Cisco VisionWay network management and customer service software solutions. For more information, see the "Related Documentation" section.

Enterprise routing

Multi-protocol routing

Dynamic routing protocols (for example, RIP, OSPF, EIGRP)

Important Notes

The following sections contain important notes about Cisco IOS Release 11.3(4)HA and the Cisco ISR 3303.

ServiceWay Command Default Value

For Cisco IOS Release 11.3(4)HA3 only, the swy max-msg-size command default value differs from the number specified in the Cisco ISR 3303 Command Reference, 16384 bytes. For this release, the default value is 32768 bytes.

The ServiceWay agent enforces a limit on the maximum message size that is accepted from ServiceWay clients and servers. A message exceeding this size is considered a protocol error and results in closure of the TCP connection. To change the maximum message size, use the swy max-msg-size configuration command. The default value is 32768 bytes, with a minimum value of 2048 and a maximum value of 65536 bytes. This parameter should not be changed without similar corresponding changes to both the ServiceWay client and server.

Deprecated MIBs

Old Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBS are currently being migrated into more scalable MIBs—without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in the following table.

Open Caveats—Release 11.3(4)HA3

This section describes possibly unexpected behavior by Release 11.3(4)HA3.

CSCdm28857

Symptom: The secondary SAM-3 card crashes when an equipment protection switch is forced from the primary SAM-3 card. Shortly after executing the switch command, control is relinquished to the secondary, which crashes upon receiving control, and control is given back to the original primary (online) SAM-3 card. In general, the forced equipment protection switch fails.

The fault may relate to

0x6049507c:RBTreeLexiNode(0x60494f9c)+0xe0

Condition: This problem has been observed on the Cisco ISR 3303 platform.

This problem occurred on an internal Cisco engineering release and has not been reproducible.

Workaround: There are no known workarounds for this problem. Please report this problem if you observe it.

CSCdm29830

Symptom: The packet processing subsystems on both the primary and secondary SAM-3 cards fail to receive any interrupts from the Ethernet and serial interfaces (GALNET, DEC, and F32) devices. The command show stackno shows only one interrupt being received under the section "Network interfaces." Performing equipment protection switches between the two SAM-3 cards does not resolve the problem. Power cycling the entire node resolves the problem and brings the node back into normal operation.

Note that this problem was originally observed as an IPC failure problem. If the serial interfaces are not receiving interrupts, the IPC subsystem cannot establish a session with its peer.

Condition: This problem appears only on Cisco ISR 3303 platforms. No other Cisco platforms are affected by the bug because the Cisco ISR 3303 uses a different redundancy model.

This problem occurred on an internal Cisco engineering release and has not been reproducible.

Workaround: There are no known workarounds for this problem. Please report this problem if you observe it.

CSCdm30965

Symptom: The system crashes with the following or similar messages:

*Apr 19 13:29:26: %SYS-3-OVERRUN: Block overrun at 611CA700 (red zone 000110DF)

-Traceback= 600C7D34 600C9200 60430ED0 604310B8 60437804 60445E40 6014FA80 600C1820 600C180C

Conditions: This problem was observed when ISRs were in a ring running DS1 and bridged Ethernet traffic. Visionway was continuously polling the ISRs. The mallocfree errors were coming from the SNMP task and did not make any sense. The root cause is believed to be something else. The problem occurred when the system was unattended and was never reproduced.

Workaround: Cycle the power.

CSCpk00520

Symptom: Console response becomes sluggish, followed by an equipment switchover.

Conditions: This problem occurred when deleting eight DS1 cross-connects, using cut-and-paste to an Xterm window console. It is believed that the cut-and-paste may have caused the problem due to rapid entry of commands. It was only seen once and could not be reproduced despite repeated attempts.

Workaround: None. The problem is cleared by the switchover.

CSCpk01035

Symptom: The SAM-3 crashed after executing the show configuration command. The apparent location of the crash is:

0x6047F244:bc_odd_loop(0x6047f230)+0x14

Conditions: This problem was observed in an early internal engineering release in December 1998 and has not been reproduced.

Workaround: There are no known workarounds for this problem. Please report this problem if you observe it.

CSCpk01245

Symptom: ROMMON fails to boot IOS via ROMMON-level TFTP command after repeated retries. The following error message appears after the last retry.

***** WATCHDOG RESET ***** EIDEC21041[00:90:24:00:03:FE] * EH ***** WATCHDOG RESET ***** EIDEC21041[00:90:24:00:03:FE] * EH ***** WATCHDOG RESET ***** EIDEC21041[00:90:24:00:03:FE] * EH ***** WATCHDOG RESET ***** EIDEC21041[00:90:24:00:03:FE] * EH OK !

*** TLB (Load/Fetch) Exception *** Access address = 0x0

Condition: This problem was observed on a Cisco ISR 3303 platform.

This problem occurred on an internal Cisco engineering release and has not been reproducible.

Workaround: There are no known workarounds for this problem. Please report this problem if you observe it.

CSCpk02243

Symptom: A crash was observed in the snmp_partition_task function. The crash appears to have occurred during an attempt to transfer a file into flash via the SNMP MIB.

This problem is believed to affect only the c3303-i4-mz image. The c3303-i4-mz image has a newly designed flash MIB for IFS-based flash filesystem in a 11.3 code base. Most 11.3 images will not have both IFS and a flash MIB.

The crash stack associated with the error is as follows:

0x600da6bc:handle_exception(0x600da45c)+0x260 0x60489fe8:snmp_partition_task(0x60489fc0)+0x28 0x600c190c:r4k_process_dispatch(0x600c18f8)+0x14 0x600c18f8:r4k_process_dispatch(0x600c18f8)+0x0

Conditions: This problem appeared on the Cisco ISR 3303 platform.

This problem occurred on an internal Cisco engineering release and has not been reproducible.

Workaround: There are no known workarounds for this problem. Please report this problem if you observe it.

CSCpk02328

Symptom: The flash filesystem reports a constant busy condition, and the following message is emitted approximately once a second.

flashfs[4]: reading from flash handle 0x60B73FC4, offset 0x33ED98: Illegal Operation -- setting bit(s) with write operation

It is believed accesses to flash may be impaired, but it is possible the flash may be working properly.

Conditions: This problem is believed to appear only on Cisco ISR 3303 platforms.

This problem occurred on an internal Cisco engineering release and has not been reproducible.

Workaround: The affected SAM-3 card must be reset for this problem to be cleared.

CSCpk02334

Symptom: SAM-3 card crashes in the following area, and secondary SAM takes over.

0x6033df14:ipc_thread_yank(0x6033de24)+0xf0 0x60336e3c:ipc_process_message(0x60336c90)+0x1ac 0x603378e4:ipc_process_raw_pak(0x60337868)+0x7c 0x6033f0e8:ipc_udp_input(0x6033f084)+0x64 0x60108e38:udp_process(0x60108d50)+0xe8

The IPC message data structure appears to be damaged, causing the ipc_thread_yank function to branch to an unknown address.

Condition: This problem appears only on Cisco ISR 3303 platforms. No other Cisco platforms are affected by the bug because the Cisco ISR 3303 uses a different redundancy model.

This problem occurred on an internal Cisco engineering release and has not been reproducible.

Workaround: There are no known workarounds for this problem. Please report this problem if you observe it.

CSCpk02382

Symptom: The flash filesystem reports a constant busy condition, and the following message is emitted approximately once a second.

%Error opening flash:/ (Device of resource busy)

Attempts to read and write files into the flash filesystem fail. It appears that multiple processes are trying to obtain access to a semaphore that is not released.

Conditions: This problem probably appears only on Cisco ISR 3303 platforms.

This problem occurred on an internal Cisco engineering release and has not been reproducible.

Workaround: The affected SAM-3 card must be reset for this problem to be cleared.

CSCpk02691

Symptom: The PM data for Ethernet ports appears incorrectly on Visionway.

Conditions: No particular conditions were required to produce the problem. The data in the MIB had the wrong ifIndex values. This problem has not been reproducible.

Workaround: Use the equipment protection switching command ine oper sw-dx-eqpt.

CSCpk02800

Symptom: The flash filesystem is damaged and all of the files in the flash file are lost, including image and configuration files. The problem appears to be a side effect of a problem related to a hardware fault, which was cleared only on a full power-cycle of the affected SAM-3 card.

A reset of the SAM-3 card using the push-button reset has no effect. The fsck command reports errors when accessing the flash device, and cannot clear the problem after the soft-reset of the SAM-3 device. Upon doing a power reset of the SAM-3 card, the flash filesystem becomes accessible, but all of the files are lost.

Conditions: This problem appeared on the Cisco ISR 3303 platform.

This problem occurred on an internal Cisco engineering release and has not been reproducible.

Workaround: There are no known workarounds for this problem. Please report this problem if you observe it.

CSCpk03475

Symptom: It may take a long time for the secondary SAM-3 card to transition to the Standby state and serve as protection when the primary SAM-3 card is very busy servicing packet traffic. The SAM-3 is so busy servicing interrupts from the packet interfaces that normal-priority processes do not run long enough to successfully complete activities. Specifically, the CSM process in the Cisco ISR 3303 does not receive adequate processing time.

Condition: This problem appears principally during heavy traffic loading conditions—when the total traffic load in the neighborhood of 100 kbps.

Workaround: You can work around the problem by setting network I/O throttling with the command scheduler allocate 3000 10000 to give the process more time.

Note that setting a larger process time value reduces packet forwarding performance. This is a trade-off to avoid the caveat. Under normal traffic conditions, the default setting for network I/O throttle is adequate.

CSCpk03591

Symptom: While configuring the Section DCC B interface, the secondary (standby) SAM-3 card crashes, resulting in a temporary loss of equipment protection capability. There is no impact on the primary (online) SAM-3 card, but protection during the time it takes for the secondary SAM-3 to reboot and resynchronize. There is no loss of traffic.

When the SAM-3 card on the standby crashes, several alarms are generated, signaling failure as follows:

*Jan 8 00:56:55: %ISR_EQ-3-SAM_NO_PROT: [0026]SAM unprotected declared on SAM A: Minor, NSA,

*Jan 8 00:56:55: %ISR_EQ-3-SAM_FAIL: [0027]SAM Failure declared on SAM B: Minor, NSA,

*Jan 8 00:57:29: %ISR_EQ-3-IPC_FAIL: [0028]Active-Standby SAM comm fail declared: Minor, NSA

*Jan 8 00:57:29: %ISR_EQ-3-DB_SYNC: [0029]Active-Standby SAM database mismatch declared: Minor, NSA

Conditions: This problem appears only on Cisco ISR 3303 platforms. No other Cisco platforms are affected by the bug because the Cisco ISR 3303 uses a different redundancy model.

This problem occurred on an internal Cisco engineering release and has not been reproducible.

Workaround: There are no known workarounds for this problem. Please report this problem if you observe it.

Resolved Caveats—Release 11.3(4)HA3

CSCdm52540

Symptom: A serial channel may suffer from excessive delay due to a packet being buffered on the receive DMA path within the F32 device. When issuing ping messages, the reception of packet n+1 flushes packet n from the receive queue. This effectively causes a one packet time delay with no packet traffic loss unless the application declares a delay loss (e.g., ping timeout). Applications may suffer from excessive delay or in some instances the effect may be difficult to observe due to large window sizes and retransmission. PPP keepalives will also flush the receive queue.

This problem appears when issuing ICMP pings. The link may show high loss rates because of delay loss. Increasing the ICMP echo timeout may not improve ping results. The user can turn on debugging via the command debug ip icmp to see that ICMP packets are being received late.

Workaround: When this problem occurs, the affected serial channel can be corrected by manually re-provisioning the channel. Manual re-provisioning of the channel is performed by putting the serial channel into loopback and then removing the loopback. Use the interface command loopback channel and no loopback channel to accomplish this. Placing the serial channel into shutdown mode and the re-activating it will not resolve the problem.

CSCdm54978

Symptom: A bridged PPP serial link fails to forward traffic due to incorrect counting of the number of outstanding packets via the input queue count. The problem occurs only when transparent bridging is turned on a serial link with PPP encapsulation, but does not occur with ML-PPP encapsulation. The input queue count is not decremented correctly when BPDUs and CPD packets are received and passed to the bridge process. Packets that already have a forwarding entry are not affected by this problem.

Condition: This problem appears only on the ISR 3303a platform when PPP and transparent bridging are enabled on an serial channel.

Workaround: A possible workaround is to use ML-PPP with a single PPP link. If the problem has already taken place, the affected SAM needs to be rebooted for the problem to clear.

The Cisco IOS software documentation set consists of the Cisco IOS configuration guides, Cisco IOS command references, and several other supporting documents. These documents are shipped with your order in electronic form on the Documentation CD-ROM—unless you specifically ordered the printed versions.

Documentation Modules

Each module in the Cisco IOS documentation set consists of two books: a configuration guide and a corresponding command reference. Chapters in a configuration guide describe protocols, configuration tasks, Cisco IOS software functionality functionality, and contain comprehensive configuration examples. Chapters in a command reference provide complete command syntax information. Use each configuration guide with its corresponding command reference.

On CCO and the Documentation CD-ROM, two master hot-linked documents provide information for the Cisco IOS software documentation set: configuration guides and command references.
