Changes to the Release Notes
This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15302 Release 2.0.2 since the production of the Cisco ONS 15302 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 15302. 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.

DDTS # CSCeg59263
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 01:80:C2:00:00:14 and:15 (IS hello), but 01:80:C2:00:00:14 and:15 are not forwarded if one is employing Provider VLAN by using Ethertype 0xFFFF (legacy provider VLAN). The condition for this issue is to have legacy VLAN tunneling in use.
DDTS # CSCea33042
Same priority and same packet size may yield different traffic flows. When four streams are set up and each has the same packet size (64 byte) going across a 100 MB STM-1 path to another ONS 15305, each of the streams can be off as much as 50%. This is not always the case, however. Sometimes the traffic can be equally distributed. Using random packet sizes, the distribution tends to be more equal. This type of traffic in not typical for a device in normal operation; however, the issue can occur in a lab test. This issue will be resolved in a future release.
DDTS # CSCeg59341
Incorrect SYSTEM-UP-TIME. 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). Ongoing investigation.
DDTS # CSCeg59350
Incorrect description of "Ping events". When using "ping utility" from CiscoEdgeCraft, and the ping is not successful, abortTftp events are reported. Tftp events are not relevant in this context. Ongoing investigation.
DDTS # CSCeg59356
In some cases the different priority tags of frames going out on WAN ports are ignored. This will be the case when 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 100Mbit/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.
DDTS # CSCeg59367
The device restarts when disabling OSPF if stub area exists.
DDTS # CSCeg59373
Administratively set a value for Unicast-Global-Forwarding Table causes device restart.
If configuring a value for Unicast-Global-Forwarding table "AfterReset" 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.
DDTS # CSCeg59382
When aging time is set above 650 seconds, it will still start at 650 seconds. This issue is observed when the following are executed:
•
•
DDTS # CSCeg59390
If both RSTP and GVRP run simultaneously, a device-restart may be experienced when disabling GVRP.
Workaround
RSTP must be disabled before disabling GVRP.
DDTS # CSCeg59396
The protocol tunneling works for VTP, CDP and RSTP protocols, but is not able to tunnel normal STP packages. This issue will be resolved in an upcoming release.
DDTS # CSCef88892
When first configuring IP numbered DCN management link between ONS15302 and ONS15454SDH, the link may not come up.
Workaround
For the DCN link to come up, toggle the mode field on ONS 15302, from "IpOverDcc" to "Not Used" then back to "IpOverDcc."

Note
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: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:

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.
