Introduction

The Cisco ONS 15303 is a high-density access platform with full SONET (Synchronous Optical Network) 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 ONS 15303 dramatically reduces cost of ownership by enabling service providers to deliver TDM and data services on a single platform over SONET optical fiber networks.

The Cisco ONS 15303 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 ONS 15303 provides extensive facility and equipment protection for high network availability. From deployed services, the Cisco ONS 15303 provides eight clear-channel DS1 TDM service delivery channels, and eight 10-Mbps IP service delivery channels using the Ethernet medium.

The Cisco ONS 15303 is designed to use static and policy routing for most of its applications. Release 11.3(4)HA5 makes Cisco IOS IP and bridging functionality available on the Cisco ONS 15303.

For the Cisco ONS 15303, Cisco also offers optional Cisco Transport Manager network management and customer service software solutions. For more information, see the "Related Documentation" section.

System Requirements

This section describes the system requirements for Release 11.3(4)HA5:

Memory Requirements

Cisco IOS Release 11.3(4)HA5 for the Cisco ONS 15303 has the following memory requirements:

Hardware Supported

Cisco IOS Release 11.3(4) HA5 supports the Cisco ONS 15303, which is available in two configurations:

For electromagnetic interference (EMI) regulatory compliance, you should use a blank SONET access module (SAM), part number ONS 15303-BLANK, with the second, non-redundant configuration.

In addition, a SAM (also called an OC-3 intermediate reach optical spare module) with SC connectors is available (part number ISR-OC3-IR-SC).

An Ethernet (10BaseT) LAN interface is supported on the Cisco ONS 15303.

The Cisco ONS 15303 supports the following WAN interfaces:

Determining Your Software Release

To determine the version of Cisco IOS software currently running on your Cisco ONS 15303, log in to the Cisco ONS 15303 and enter the show version command.

router>show version
Cisco Internetwork Operating System Software 
IOS (tm) Cisco ONS 15303 Software (c3303-i4-mz), Version 11.3(4)HA5, RELEASE SOFTWARE

Feature Sets

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. In Cisco IOS Release 11.3(4)HA5, there is only one image, c3303-i4-mz, and one feature set, IP Subset with Connectionless Network Service (CLNS). The image includes the features listed in the next section.

New and Changed Information

The following list includes the hardware and software features supported by Release 11.3(4)HA5 for the Cisco ONS 15303:

Limitations and Restrictions

Because the Cisco ONS 15303 is intended to use static and policy routing for most of its applications, the following functions are not available in Cisco IOS Release 11.3(4)HA5:

Important Notes

The following sections contain important notes about Cisco IOS Release 11.3(4)HA5 and the Cisco ONS 15303.

Replacing a Single SAM or Both SAMs

When replacing a SAM in a non-redundant chassis or replacing both SAMs in a redundant chassis, you may see several of the LEDs flash every 60 to 90 seconds. This condition is not service affecting and does not raise an alarm. To stop the LEDs from flashing, wait for the SAM to go active (in a non-redundant chassis) or wait for one of the SAMs to go active (in a redundant chassis), and turn the power to the Cisco ONS 15303 off and then on. An alternate method is to pull out the SAM and then re-insert it.

Default Configuration Web Location

If you need a copy of the original default configuration that appears on the Cisco ONS 15303 when it was shipped from manufacturing, go to http://www.cisco.com/cgi-bin/Software/Iosplanner/Planner-tool/iosplanner.cgi. Navigate to the 11.3 release and the Cisco ONS 15303.

No IP Routing Command

Do not issue the no ip routing command globally on the Cisco ONS 15303 because communication between the two SAM processors may get corrupted.

Cisco Transport Manager/Customer Network Management Command Default Value

For Cisco IOS Release 11.3(4)HA5 only, the cnm max-msg-size command default value differs from the number specified in the Cisco ONS 15303 Command Reference, 16384 bytes. For this release, the default value is 32768 bytes.

The Cisco Transport Manager/CNM agent enforces a limit on the maximum message size that is accepted from Cisco Transport Manager/CNM 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 cnm 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 Cisco Transport Manager/CNM 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.

Caveats

Caveats describe unexpected behavior or defects in Cisco IOS software releases. This section only contains open and resolved caveats for the current Cisco IOS maintenance release.

For information on caveats in Cisco IOS Release 11.3, refer to the "Important Notes and Caveats for Release 11.3"  section in the cross-platform Release Notes for Cisco IOS Release 11.3  document which is located on CCO and the Documentation CD-ROM. These release notes describe caveats affecting all maintenance releases and list severity 1 and 2 caveats for Cisco IOS 11.3. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

Note If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for any release. From CCO, log in and click on this path: Service & Support: Online Technical Support: Software Bug Toolkit. You can also find Bug Navigator II at http://www.cisco.com/support/bugtools.

Open Caveats---Release 11.3(4)HA5

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 stack no 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 ONS 15303 platforms. No other Cisco platforms are affected by the bug because the Cisco ONS 15303 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.
Symptom: Under artificial tests with a traffic generator in a bridged environment, loss of system processor memory may result. This may eventually cause the console to hang.
Condition: (1) In a pure bridge configuration (no IRB and no CRB enabled), after approximately 36 hours with a continuous line rate of 1536 bytes frames, a console hang may occur. (2) In a bridge configuration with CRB enabled, the system may lose memory after approximately 48 hours with a continuous line rate of 1536 bytes frames. Both conditions are caused by memory leaks and the cause is yet to be determined.
Workaround: Lower the traffic rate to less than the line rate of the PPP serial pipes assigned to the Ethernet interface.
Symptom: An unexpected LOS and/or LOF alarm is reported on one of the OC-3 interfaces. This causes a protection switch to the other interface.
Condition: The optical transceivers, on very rare occasions, do not function correctly for a short period after power-up. The problem typically clears within five minutes.
Workaround: There are no known workarounds for this problem. The system's protection switching mechanisms protects the user traffic, and the problem clears without user intervention. After the problem clears, the alarms will clear and the interface will once again be available to carry traffic.
Symptom: A VT Signal Degrade, Signal Fail, or Path Signal Label Mismatch alarm is reported, resulting in a protection switch for that VT. The alarm will only affect one side (A or B) and will occur when there are no known problems in the network.
Condition: This problem will only occur after reboot or changing an STS from pass-through to drop-terminated or vice-versa, and is very, very rare. The root cause is a bug in one of the devices on the SAM (the TUPP). The vendor has committed to fix the bug in a later release of the chip.
Workaround: Remove and re-insert the affected SAM.

Resolved Caveats for Release 11.3(1) through 11.3(3)HA

Symptom: In some rare cases, the system crashes with timer corruption.
Condition: This problem has been reported in other Cisco products and appeared during manufacturing switchover testing on the Cisco ONS 15303. Sometimes a board that went from standby to active would crash in the first minute or so that it was up. The other board would then go active and there would not be any significant loss of traffic. However, in other IOS products without redundancy, an outage would occur until the router rebooted.
Workaround: There is no known workaround. Please report this problem if you observe it.
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, but no packet traffic is lost, 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.
Condition: This problem can be observed 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 debug ip icmp to see that ICMP packets are in being received late.
Workaround: When this problem occurs, the affected serial channel can be corrected by manually re-provisioning the channel. Manual re-provisioning the channel by putting the serial channel into loopback and then removing the loopback. Use the interface command loopback channel and no loopback channel . Placing the serial channel into shutdown mode and then re-activating it will not resolve the problem.
Symptom: A bridged PPP serial link may fail to forward traffic due to incorrectly counting 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 ONS 15303 platform when PPP and transparent bridging are enabled on an serial channel.
Workaround: A possible workaround is to use a 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.
Symptom: During initialization of a SAM-3 card, the PCI system controller may report a fatal error while initializing the Ethernet management port (Ethernet 0). The other SAM-3 in the system will take over and the traffic should only be minimally affected. The following error message will be display on the console of the failed SAM-3 card:
%ERR-1-NILE4: Fatal error, PCI Master Abort, CPU was initiator
The crash stack associated with the problem is as follows:
0x601c5c14:dec21043_stop(0x601c5bc4)+0x50 0x601c6c70:dec21043_init(0x601c6c28)+0x48 0x601c7c50:dec21043_init_interface(0x601c7bbc)+0x94 0x601c7dfc:dec21043_analyze_device(0x601c7dbc)+0x40 0x601c8430:dec21043_1fe_analyze_pa(0x601c83d8)+0x58
Condition: This problem appears only on the Cisco ONS 15303. This problem occurred on an internal Cisco engineering release, and has not been reproduced.
Workaround: There are no known workarounds for this problem. Please report this problem if you observe it.
Symptom: The DCC communication channel between the Cisco ONS 15454 and the Cisco ONS 15303 does not work properly.
Condition: This problem occurred during interoperability testing between the Cisco ONS 15454 and the Cisco ONS 15303 in the lab. The cause was due to the Cisco ONS 15454 using 32 bit CRC and the Cisco ONS 15303 using 16 bit CRC.
Workaround: Use the interface serialds1 interface number crc 32 command to change the Cisco ONS 15303 CRC to 32 bit. The CRC can be changed back to 16 bit by entering interface serialds1 interface number crc16.
