Changes to the Release Notes

This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15302 Release 1.0.1 since the production of the Cisco ONS 15302 System Software CD for Release 1.0.1.

No changes have been added to the release notes for Release 1.0.1.


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 # CSCdz25077

When using the ONS 15302 as a distribution switch connected to an IP multicast router, the ONS 15302 should forward IGMP join and leave packets to the router. However, when operating in basic bridge mode, IGMP join and leave messages are not forwarded to other ports in the VLAN. The ONS 15302 supports dedicated forwarding tables for MAC layer multicast traffic and IGMP snooping. By enabling these features as follows, you can ensure that the IGMP packets are forwarded correctly.

Step 1 Step 1 To reduce the maximum number of VLANs to less than 4000 and make space available for the MAC multicast tables (this is a one-to-one relation, so for every VLAN you take off, you can have another multicast group entry), enter the commands:

\Services\Device-Tuning\General Vlan=3900

The device reboots.

Step 2 Step 2 To enable the MAC multicast feature, enter the command:

\Bridge\Multicast\parameters multicast=true

Step 3 Step 3 To enable the IGMP snooping feature, enter the command:

\Bridge\IGMP-Snooping\parameters IGMP=true

Now, when IGMP join messages are received from an end user, the transaction will be registered in the bridge and forwarded to the other ports in the VLAN. The related multicast traffic will now be forwarded only to the bridge port of the received the IGMP join message. IGMP leave messages will be forwarded only, and the registered IGMP entries in the bridge will time out (default 150 seconds). This issue will be resolved in a future release.

DDTS # CSCdz37795

A LAN port may lose traffic or packets when another LAN becomes congested, or packets otherwise overload the port. For example, connect two ONS 15302s (A and B) back to back. Set up a VLAN between A1 and B1 and another VLAN between A2 and B2. Run all ports in 100 MB mode with flow control on. Offer 30 MB from A1 to B1 and 30 MB from A2 to B2. Then reduce the B1 mode to 10 MB. Packet loss will be observed. To avoid this issue, do not use different speeds on the LAN-ports. Note that if the WAN capacity is lower than the slowest LAN-port, the issue will not occur (flow control will work). This issue will be resolved in a future release.

DDTS # CSCdz22948

The ONS 15302 cannot be provisioned with the same IP subnet on its management interfaces; for example, the management port and one or more of the DCC channels. All IP interfaces must be provisioned with a dedicated IP subnet. Introducing an ONS 15302 into an ONS 15454 topology where all the ONS 15454 management interfaces are on the same subnet, only one management interface of the ONS 15302 can be provisioned on that subnet. To work around this, provision the "ONS 15454 subnet" for the "A-DCC-R" interface, and provision a different subnet to the management port of the ONS 15302. This issue will be resolved in a future release.

DDTS # CSCdz26587

There is no immediate connectivity when managing an ONS 15302 via an ONS 15454 running proxy ARP. Add static routes on the management station or PC to work around this issue. This issue will be resolved in a future release.

DDTS # CSCdz26606

During failure in an ONS 15454 ring where static routes have been provisioned over the link that fails, the ONS 15302 loses connectivity due to an inability to interoperate with OSPF. If the ONS 15454 allows more than one static route to the same destination, but through different interfaces, then "back-up" routes can be provisioned to avoid this issue. This issue will be resolved in a future release.

DDTS # CSCdz34676

AIS is not transmitted to the E1 customer side after an LOSS on the far end. This is standard behavior according to PRA specification ETS 300-233. This caveat is informational only, and no change is planned for the ONS 15302.

DDTS # CSCee44539

SYSTEM-UP-TIME is incorrect . System- up- time should be able to store up- time up to approximately 497 days. Counters reset at approximately 40 days, causing the up time to display incorrectly. This issue is under ongoing investigation.

DDTS # CSCee44556

A restart is triggered when receiving a specific frame (BOOTP). An ONS 15302 connected to a common HUB via MNGT-port reboot after having been in operation for some time. ROS is sensitive to specific frames (BOOTP) and this causes a software restart. This vulnerability applies for all IP-addressed ports (LAN/WAN/MNGT). This issue is under ongoing investigation.


Turn off BootP messaging from the router (in this specific case).

DDTS # CSCee44553

"Ping events"are incorrectly described. When using the "ping utility" from CiscoEdgeCraft, if the ping is not successful, abortTftp events are reported. Tftp events are not relevant in this context. This issue is under ongoing investigation.

DDTS # CSCee44582

ONSCLI commands for IP DCN configuration are missing. ONS 15302s have numerous features for advanced configuration to achieve IP connectivity from a Network operation center. Current and previous versions of ONS 15302 SW do not provide commands in ONSCLI to manage routing tables and routing protocols supported by NEs.


Use CiscoEdgeCraft for IP DCN configuration.

This issue will be resolved in a future release.


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


Verify the SW-ICS by means of VT100 or CEC. For R1.0.1, the correct SW ICS is ICS08.

This issue will be resolved in a future release.

False WAN-sequence fail alarm when connected to older VCTE-FPGA

PM does not count SES/UAS at VC-12 UNEQ/TIM alarms

SW-download automatic fallback mechanism corrected/improved

Forwarding of STP BPDU's when STP disabled

IS-IS Multicast packets not forwarded

Pause packets has SA MAC = 00:00:00:00:00:00

STP topology change timer corrected

Problem with RMON Counters wrap-around

Incorrect formatted log-file events

Full traffic stop on the WAN port when the difference in the delay between the VC-12 with shortest delay and the VC-12 with longest delay becomes longer than 200 us.

The aggregate port Rx-level is not shown when the port's operational status is down.

The RS-SES and RS-UAS alarms do not increment to indicate error condition when injecting B1 errors at the rate of 10E-4. Behavior is correct when LOS or LOF is injected.

MSP DNR (Do Not Revert) is not sent out after a manual clear when the device is operating in non-revertive mode.

It was possible to manage the autonegotiation, speed and duplex mode parameters on the WAN ports. This does not make sense, since the WAN ports always operate with autonegotiation disabled, 100 MB and full duplex mode

Flow control on WAN ports is always in status on after a device reboot

Protection commands available in ONSCLI even if device is unprotected

Command type noCommand should not be presented as an available option in ONSCLI help text for PROTECTION.SWITCHING-COMMAND

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.
