Changes to the Release Notes

This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15305 Release 2.0.2 since the production of the Cisco ONS 15305 System Software CD for Release 2.0.2.

No changes have been added to the release notes for Release 2.0.2.

Caveats

Review the notes listed below before deploying the ONS 15305. Caveats with DDTS tracking numbers are known system limitations that are scheduled to be addressed in a subsequent release. Caveats without DDTS tracking numbers are provided to point out procedural or situational considerations when deploying the product.

DDTS # CSCei15120

Incoming IGMP packets are VLAN-tagged, and hold the VID of a VLAN that is configured on the device. The ingress port is not a member of a named VLAN. In some rare configurations this could create a loop in the topology, and a storm of replicated IGMP packets. The IGMP packets reach the VLAN even though the ingress port is not member of the VLAN. Thus VLAN-tagged IGMP packets bypass ingress filtering.

Workaround

There is usually no need for a configuration that allows this to happen.

Verify that the VLAN configuration in the topology is consistent and does not contain any partially configured links. This issue is under investigation.

DDTS # CSCei15125

Changing the system mode from IP (default) to IP unnumbered can result in problems.

Release 2.0 software is limited with respect to changing the system mode from IP (default) to IP unnumbered.

Even though there are IP addresses and routing protocols configured on an NE the operator does not receive any notification. Notification could enable the operator to forestall the change until necessary configuration changes have been made.

From a software design point of view, the configuration of system mode for DCN routing is seen as a strategic choice, which the operator should configure prior to configuring the IP address and protocols on the device. The reason for this is that the network design is different for each of the system modes.

The consequence for changing the system mode from IP to IP unnumbered is complicated and severe problems can result if handled incorrectly. In the worst case, you might not be able to regain IP connectivity to the NE.

Workaround

Generally, the safest alternative is to erase the configuration prior to changing the system mode. If you do not wish to lose your configuration, however, the following steps have proved successful.


Step 1 Locally connect to a MNGT-port and connect with CiscoEdgeCraft.

Step 2 Remove all IP addresses in the IP interface table except for the MNGT-port address (IF=1000).

Step 3 Remove all static configured routes (even the 0.0.0.0 route).

Step 4 Disable active routing protocols (RIP and/or OSPF).

Step 5 Locally connect to the device via ONSCLI (VT100).

Step 6 Remove the IP address assigned to the management port (ONSCLI>ip ip=0.0.0.0 sub=0.0.0.0).

Step 7 Set the system mode to IP unnumbered (IPUN) and reset the device.

Step 8 Change the IP address (MNGT-port) to fit your new network design and reconfigure the SNMP community.

Step 9 Reconnect to the device with CiscoEdgeCraft.

Step 10 Commission IP unnumbered configuration; IP over PPP (DCC), OSPF, etc.



Note This procedure cannot be obtained via remote access to the network element.


Resolution

N/A

DDTS # CSCeg61386

FE port blocked when a port configuration is changed. The port does not forward traffic, but port status is reported as up.

This issue can occur when the FE port has been configured for L1 and a bandwidth larger than 0 has been allocated. If the port is reconfigured to L2, the port will not forward traffic when there is an alarm on the vcgroup connected to the port, in L1 mode, prior to the reconfiguration to L2.

Workaround:

Ensure that on a port running in L1 mode, with an administrative capacity larger than 0, your operational capacity downstream is larger than 0, then reduce the administrative bandwidth of the port to 0 before switching over to L2 configuration.

If a reconfiguration of the port has occurred without following the above procedure, the module must be restarted. A reconfiguration back to L1 operation will not be sufficient unless an operational capacity greater than zero is restored and the procedure described above is repeated. This issue will be resolved in the next release.

DDTS # CSCea33337

Port priority is not strictly enforced when flow control is on. This can occur under the following conditions.

The four input ports are set for 100 MB (64 bytes).

Port 1 priority is set for 6

Port 2 priority is set for 4

Port 3 priority is set for 0

"Port 4 priority is set for 1

VLAN tagging is turned off for all of the FE ports while VLAN tagging is turned on for the STM1 trunk port. (This adds an additional 4 bytes to each stream.) Flow control is turned on for all the FE ports When all the ports are turned on, only Port 1 should have priority. Instead, traffic is received on both Ports 1 and 2 at almost 60/40% on each port (81,168 versus 60,876). This issue will be resolved in a future release.

DDTS # CSCeb22543

The failure is present in different corners and at different temperatures. We have Errors (#14 B3 errors in 24 hour of test, #1 Loss of Pattern) on a STM-1 link with #3 8xSTM-1 modules. We records also packet lost on a FE link mapped into STM-1 optical path. When these errors / packet lost happens, we record from Cisco Craft a lot of "DXC inlet bit error" alarms. No other type of alarms has been recorded from the Cisco-Craft. All these 3 event happens at the same time, so the root cause should be the same.

DDTS # CSCea71600

The fail is related on module 8xSTM-1. During EDVT corner 5 & corner 7:

Corner 5: power supplies on the modules at -5% except power supply DC-DC module at +5%, Temperature= +50°C

Corner 7: each power supplies at -5%, Temperature= +50°C this module does not starts. This cause fail on the traffic path related to this modules.

The number of fails is:

C5:board_3 module 8xSTM-1 SN0307008095, 2 times / 10 tests

C7:board_3 module 8xSTM-1 SN0307008095, 1 time / 10 tests

C7:board_4 module 8xSTM-1 SN0303006397, 1 time / 10 tests

When this fail happens, record the following alarm from the Cisco EdgeCraft:

"slot3 inlet Fail DXC inlet failure".

64 byte packets are lost when testing flow control

DDTS # CSCea31245

Conditions:

When sending 100 Mb from two ports to a single port, the packets are lost when the size is 64 byte. When the size is increased to 75 byte, the packet loss goes away

Workaround:

This type of traffic is not typical for a device in normal operation but it can occur in a lab test setup

Resolution:

None

DDTS # CSCea33354

No pause packets received on ports sending traffic to a congested mirrored port.

Conditions:

If a mirrored port becomes congested and flow control is enabled, no pause packets are generated toward ports belonging to other modules. Flow control is not working properly if ports used for mirroring become congested. If traffic to a mirrored port is sent from a LAN port situated in a different module than the mirrored port pause packets are not received and mirrored packets are lost. The real traffic flow is not disturbed by the mirrored port flow control problem, and the copy port traffic handling is working fine.

Workaround:

None

DDTS # CSCeg58254

When operating in L2 mode, Ethernet frames with MAC destination address in the range 01:80:C2:00:00:10 to 01:80:C2:00:00:FF are not correctly filtered due to limitations in the switch ASIC. Special steps are taken to forward 0 1:80:C2:00:00:14 and:15 (IS hello).

01:80:C2:00:00:14 and:15 are not forwarded if one is employing Provider VLAN by using Ethertype 0xFFFF (legacy provider VLAN).

Conditions:

Legacy VLAN tunneling in use.

Workaround:

Use protocol tunneling supported by 2xGE + SMAP and 8xFE + SMAP to provide transparent Ethernet (with or without provider VLAN).

DDTS # CSCea33042

Same priority and same packet size yields different traffic flows.

Conditions:

There are 4 streams setup each has the same packet size (64 byte) going across 100 Mb STM-1 path to another ONS15305. Each of the streams can be off as much as 50%. This is not always the case, sometimes the traffic can be equally distributed. However, using random packet sizes, the distribution seems to be more equal.

Workaround:

This type of traffic in not typical for a device in normal operation, but it can occur in a lab test setup.

Resolution:

None

DDTS # CSCea33196

Unfair distribution of intermodular traffic with flow control can occur. If traffic is sent from several ports in different modules and flow control is active, traffic throughput is less for ports belonging to same module as the congested.

Typical scenario:

Port 2 module 1, port 1 module 2 and port 1 module 3 send 100Mb traffic streams to port 1 module 1. All ports have flow control enabled. The result is that more traffic is sent from the ports in module 2 and 3 compared to what is sent from the port in module 1. No packet loss from any module occurs. This issue will be resolved in a future release.

DDTS # CSCeg58260

System-up-time should be able to store up-time up to approximately 497 days. Experience shows this counters wraps around well before (appr. 40 days).

Workaround:

None

Resolution:

Ongoing investigation.

DDTS # CSCeg58273

AbortTftp events reported on unsuccessful ping.

Conditions:

When using \223ping utility\224 from AXXCRAFT, and the ping is not successful, abortTftp events are reported. Tftp events are not relevant in this context.

Workaround:

None.

DDTS # CSCeg58278

802.1p does not work satisfactorily for WAN ports on 4xFE+4xMAP, 8xSTM-1+8xMAP and 8xMAP modules.

Symptom:

In some cases the different priority tags of frames going out on WAN ports are ignored.

Conditions:

The number of VC-12s allocated to a WAN port is less than 47 (i.e. the capacity of the WAN link is less than 100M it/s). The switch sees the wan port as an FE port, and will not see the need for prioritizing between the frames. Thus adapting the traffic to the actual bandwidth is handed over to the FPGA mapping the frames into SDH.

Workaround:

Solved for 2xGE + SMAP and 8xFE + SMAP modules.

Resolution:

Ongoing investigation.

DDTS # CSCeg58295

Disabling OSPF causes device-restart if Stub area exists (IP-Numbered mode only).

Symptom:

Device restarts when disabling OSPF if stub area exists.

Workaround:

None

Resolution:

Ongoing investigation.

DDTS # CSCeg58300

Static Unicast Table (number of entries) causes device-restart.

Symptom:

Administratively set a value for Unicast-Global-Forwarding Table causes device restart.

Conditions:

If configuring a value for Unicast-Global-Forwarding table \223AfterReset\224 lower than the number of static entries in the table, and then select software reset for the device, a device restart will be experienced.

Workaround:

Avoid configuring a lower number than statically configured in the Unicast-Global-Forwarding table.

Resolution:

Ongoing investigation.

DDTS # CSCeg58312

Max aging time is 650 sec.

Symptom:

When the setting for aging time is set above 650 seconds, aging still starts at 650 seconds.

Conditions:

1. Fill the forwarding table using SmartBits to generate different source addresses (default forwarding table size is 8192).

2. The default aging time is 3600, but still the number of entries in the table starts to reduce at approximately 650 seconds.

Workaround:

None.

DDTS # CSCeg58361

Unnecessary LINK_DOWN events reported in history after boot/restart.

Symptom:

DCC Link "down" events reported in "notification history" after boot.

Conditions:

All DCC channels, even if not represented by DCC applicable HW, reports LINK "DOWN" in notification history after device power up (restart).

Workaround:

None

Resolution:

Ongoing investigation.

DDTS # CSCeg58364

Auto negotiation for Flow control on LANx-ports does not work (2xGE_SMAP only).

Symptom:

The PAUSE-capable bit is not announced during auto negotiation when Flow Control is set to AutoNeg.

Only for 2xGE_SMAP.

Workaround:

None.

Resolution:

Ongoing investigation.

DDTS # CSCeg58372

There is an RSTP and GVRP conflict.

Symptom:

If both RSTP and GVRP run simultaneously, a device-restart may be experienced when disabling GVRP.

Workaround:

RSTP must be disabled before disabling GVRP.

Resolution:

Ongoing investigation.

DDTS # CSCeg58380

SNC Protected unidirectional cross-connection not supported. When one direction of a path forms part of an SNC protected unidirectional cross-connection, the other direction can not form part of a different SNC protected unidirectional cross-connection. But the two directions can form part of two different unidirectional un-protected cross-connections. This applies to unidirectional cross-connections on all path layers.

For example, suppose the unidirectional VC-12 cross-connection from 1/1/1.1.1.1.1 (input) to 1/2/1.1.1.1.1 (output) is SNC protected by 1/3/1.1.1.1.1 (input). In this case, the output direction of 1/1/1.1.1.1.1 and /3/1.1.1.1.1, and the input direction of 1/2/1.1.1.1.1 are un-used. However, due to the above mentioned limitation, they can not be part of a new SNC protected unidirectional cross-connection, e.g. from 1/2/1.1.1.1.1 (input) to 1/1/1.1.1.1.1 (output) protected by 1/14/1.1.1.1.1. They may however form part of un-protected unidirectional cross-connections.

Workaround:

None.

Resolution:

Release R3.0

DDTS # CSCeg58388

Device reboots if switching OSPF InterfaceType from "point-to-point" to "broadcast," or if disabling OSPF while InterfaceType is "point-to-point". This issue is observed when OSPF is enabled, the OSPF Interface table is populated and the InterfaceType of an entry in the OSPF Interface table is changed to "point-to-point."

Workaround

Restore a CDB-backup without the incorrect interface type configured. If you don't have such a CDB-backup, SUPPORT can assist in modifying the CDB-backup of your current configuration.

DDTS # CSCeg58398

Device initiates an additional boot sequence when restarted after CDB-restoration, to clean up invalid configuration data, after which the ProviderTags parameter is set to "disabled."

VLAN membership or tag status of an Ethernet port has been changed after the parameter ProviderTags has been enabled, and the device has been rebooted (due to software/firmware upgrade, or restore of configuration database).

Workaround:

Disable ProviderTags parameter when removing the port from the VLAN or changing its tag status.

DDTS # CSCef88892

When first configuring IP numbered DCN management link between ONS15305 and ONS15454SDH, the link may not come up.

Workaround:

For the DCN link to come up, one must toggle the mode field, on ONS15305, from "IpOverDcc" to "Not Used" then back to "IpOverDcc".

DDTS # CSCeg11010

Some dccR and dccM Mode field may reset to "Not Used" after upgrade to R2.0 in IP numbered mode.

Workaround:

Mode fields for all pre-provisioned dccR and dccM must be revisited and reconfigured for "Poverty".

DDTS # CSCeg11478

Reverting from R2.0 back to R1.1.1 will fail.

Workaround:

The following procedure must be used to successfully revert back to Release 1.1.1, after upgrading to release 2.0:

1. Main card firmware, 45004-70AA_PM_ ED05.bin, must be uploaded first.

2. Software file, 45004-77AB_PM_ED06.bin, must be uploaded.

3. Definition file, 55004-01AB_PM_ED06.def, must be uploaded.

DDTS # CSCeg45943

The Mac table overflow "Duration Timer" does not increment.

After overloading the forwarding database a "bridge table overflow" occurs, but the duration of the condition stays at 0h 0m 0s.

Resolved Caveats for Release 2.0.2

The following caveats are resolved as of Release 2.0.2.

Packet buffer hang. No traffic is running on WAN port in the receiver direction, towards the switch port. There are no alarms or other symptoms on a failure. Can be experienced on the 8xSTM-1 modules.

Flow control enable/disable. Flow control is not disabled on the SDH side of the WAN port when flow control is disabled on the Switch side of the WAN port. The flow control packets will be dropped in the switch, and therefore the operator will see no difference in the behavior.

Pause packet detection. Packets with multicast address 01-80-C2-00-00-01 but with length/type field different from 8808 and control opcode field different from 00-01 may be misinterpreted as pause packets, and therefore lead to reduced link capacity on links where flow control is enabled. Can be experienced on the following modules: STM1-8, GE-2+MAP and E100-8+MAP.

Operational Wan-capacity calculation when Admin=0.When EoS proprietary mapping is used and the Administrative capacity is set to 0Mbit/s, the operational capacity may be reported different from 0Mbit/s. Can be experienced on the following modules: E100-8+MAP.

PM data collection. False G.826 performance errors may be reported on VC-channels in a VCG connected to a LANx or WANx port. Can be experienced on the following modules: E100-8+MAP.

MNGT-port blocked. The mngt-port occasionally locks-up, resulting in loss of management connectivity to the device. A recovery mechanism is now in place (re-initializing the transmitter).

OH-byte map-table entry is cleared (slot/port) when UNMAPPING an OH-byte configuration.

DCC-transparency corrected.

Reduce MTU on management interfaces (DCC channels) to 1500.

Fixed bug in handling of IP packets larger than 1500 bytes sent and received by CPU.

Improved System Controller diagnostics.

Remove "clear" command from terminal-prompt.

Relocation of application-code in CompactFlash, according R2.0 mapping, is corrected.

Fixed - device reboots if switching OSPF InterfaceType from "point-to-point" to "broadcast". CEC R.2.0.2 and onwards does not allow changing this parameter.

Add timer supervision on deteriorating external clock reference (2MHz sync input port).

FE port blocks when port configuration is changed (L1-L2 transition), DDTS # CSCeg61386.

Receiving OSPF LSA-update on the MNGT-port lead to reboot. (IPUN only).

Correct Temp-Serial-Buffer usage, possible device reboot when VT100/Mngt-port connected.

Extended Signal Label not presented correctly (CEC R.2.0.2 or newer is required for this feature).

The metric displayed in routing table was110 independent of hop count to destination address for routes learned via the OSPF algorithm. (IPUN only).

ONSCLI Running-configuration command improvements (alarm data / IP-data / module HW-inventory).

ONSCLI Merge debug-counters and log-file commands to "display-debug-info" and "clear-debug-info."

SNC Protected unidirectional Cross-connection are now supported. DDTS # CSCeg58380

There was a possibility for generation of crc-errors when flow-control is disabled on WAN-port.

There was a possibility that a WANx- port could stop forwarding traffic, and continuously send pause frames out on the link.

When sending Ethernet frames over 46 or more VC-12s, there was a drastic reduction in throughput when flow control was enabled (WANx-port).

When tags were inserted, the default port priority was always used for selecting forwarding queue on FE-LANx ports.

When sending Ethernet frames over proprietary EoS mapping (WANx-port), the performance was lower than on WAN-port due to the fact that 8 HDLC flags were inserted between frames instead of 1 HDLC flag.

The throughput was too low when using half duplex on FE-LANx ports.

When flow-control was enabled and the traffic consisted of frames with length 9k bytes or slightly less, some frames were dropped on FE-LANx (L1) ports.

DDTS CSCeg58364; auto negotiation for Flow control on LANx-ports now works (GE-2+MAP only).

The GFP FCS error counters did not count correct.

Certain types of LSAs entering a ring of NEs running OSPF over IPUN interfaces provoked restart of the NEs (due to endless circulation).

Enabling PRIORITY is now possible if FlowControl has ever been enabled (applied only for Ethernet ports on GE-2+MAP).

Jumbo frames are now dropped if Jumbo-frames are disabled (GE-2+MAP only). Read correct port speed (GE-2+MAP only).

The following caveats are resolved as of Release 2.0.

Back pressure with 64 bytes packets causes loss and uneven distribution

GigE port does not handle traffic in fiber w/auto Gen enabled

Restart triggered when receiving a specific frame (Bootp)

GigE port/Incorrect media/connection

Mismatch between "Running SW Revision" presented during start-up and the actual software in the equipment.

Obtaining Technical Assistance

For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service contract, contact your reseller.

Cisco Technical Support Website

The Cisco Technical Support Website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, 365 days a year, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do


Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.


Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
