Cisco Cisco ONS 15310-MA SONET Multiservice Platform Notas de publicación

This section documents supplemental changes that have been added to the Release Notes for 
Cisco ONS 15310-MA Release 8.0 since the production of the Cisco ONS 15310-MA System Software 
CD for Release 8.0.

Review the notes listed below before deploying the ONS 15310-MA. Caveats with tracking numbers are 
known system limitations that are scheduled to be addressed in a subsequent release. Caveats without 
tracking numbers are provided to point out procedural or situational considerations when deploying the 
product.

VxWorks is intended for qualified Cisco personnel only. Customer use of VxWorks is not recommended, 
nor is it supported by Cisco's Technical Assistance Center. Inappropriate use of VxWorks commands can 
have a negative and service affecting impact on your network. Please consult the troubleshooting guide 
for your release and platform for appropriate troubleshooting procedures. To exit without logging in, 
enter a Control-D (hold down the Control and D keys at the same time) at the Username prompt. To exit 
after logging in, type “logout” at the VxWorks shell prompt.

When either you remove and then reinsert an I/O card, or a small burst of defects occurs for a very short 
period (less than 1 sec), false TCAs can be triggered that indicate line or traffic problems on an I/O port. 
Once triggered, the TCAs will be raised every 15 mins, after the 15 min pm report. There are no alarms 
for the associated ports. Traffic is not affected.

The cards affected are: 

ONS 15454 DS1, DS1_E1_56, DS3 (including DS3, DS3N, DS3E, DS3NE), DS3_EC1, DS3XM, 
DWDM, E1, E1_42, OC3-8, OC12-4, MRC-12, OC192XFP; and ONS 15310-CL and ONS 15310-MA 
IO ports.

There are two workarounds:

1. Place the affected ports in OOS-DSBLD and then back to IS. This clears the problem for the specific 
port on the card, but the traffic will be down during the period of OOS-DSBLD. 

2. Soft reset the card with problem ports. This clears the problem on all ports on the card. Soft reset might 
cause a protection switch if any port on that card or the card itself is in a protection group. 

You can switch all protected ports away from the card that is to be soft-reset. In this case you can do 
manual switches away from the ports on that card, or in the case of an equipment switch, away from the 
equipment to be reset. 

You can also perform a soft reset without any pre-action. This might result in protection switches of all 
active protected ports on that card. In the case of an equipment protection group resetting, the active 
equipment might incur a protection switch. The switch time will not exceed 60 ms.

For unprotected ports or card equipment, traffic will not be affected.
