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.

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 # 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:

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

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

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."

Resolved Caveats for Release 2.0.2

The following issues are resolved as of Release 2.0.2

DDTS # CSCeg59396; STP protocol packages are not tunneled through an ONS 15302. Other protocols, such as VTP, CDP and RSTP are tunnelled properly through the ONS 15302.

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. The error is not present on WANx ports.

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 user 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

PM data collection. False G.826 performance errors may be reported on VC-channels in a VCG connected to a WANx port. The error was only present on the WANx port on the new R2.0 GFP-WAN module.

RDI generation. When the optical input signal is removed RDI shall be generated on the outgoing VC-12 containers on the WAN port, the RDI generation was not stable, resulting in a fluctuating operational WAN capacity in the remote end. The error is not present on WANx ports.

Priority to queue mapping. 802.1p did not work properly for WANx ports.

Don't allow selecting SDH Port2 as sync source on unprotected device.

GALNET diagnostics incorrectly report error.

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

Configuring path-trace for a WANx-port could not be issued from ONSCLI.

Invert alarm-output port driving (align with ONS 15305).

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

The metric displayed in routing table is 110 independent of hop count to destination address for routes learned via the OSPF algorithm. (IPUN only).

Protocol tunneling correction. (CiscoEdgeCraft R2.0 or newer is required for this feature).

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 sending Ethernet frames over proprietary 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 GFP FCS error counters did not count correct.

Extended Signal Label not presented correctly (CiscoEdgeCraft R2.0 or newer is required for this feature).

Correct Trail Signal Label decoding (VCAT-VC12) in ONSCLI.

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

The following issues are resolved as of Release 2.0.

Cannot provision same IP subnet on common PPP link.

Proxy ARP on the ONS 15454 is not supported by ONS 15302.

ONS 15302 does not interoperate with OSPF causing DCC failure.

POS, ATM, and gigE is broken in 11/11 GSR conn_isp image.

Bridge blocks IGMP message.

Other Lan port loss traffic when another Lan get congestion.

Cosmetic code refinement suggested by code review.

cnfvifccprof fails for rep more than 32 due to indexing problem.
