Cisco Cisco ONS 15454 SDH Multiservice Provisioning Platform (MSPP) 發佈版本通知

This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 
15454 SDH Release 4.6 since the production of the Cisco ONS 15454 SDH System Software CD for 
Release 4.6.

The following changes have been added to the release notes for Release 4.6.

The following caveats have been added to the release notes.

Review the notes listed below before deploying the ONS 15454 SDH. 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.

Pulling the active XCVXL card might result in a traffic outage lasting for greater than 2 seconds. It is 
possible to see this approximately 1 out of every 7 active XCVXL card pulls. Excessive traffic outage 
from this issue will not occur after a software-induced XCVXL side switch. In this case, you can expect 
a traffic hit of less than 60 ms, and traffic will resume normally.

SDH DS3-i and E3 electrical cards only support a VC4 J1 trace string setting for all VC4s together. You 
cannot set the J1 byte for individual VC4s. This issue is a limitation of hardware.    

VC3 J1 strings can be set individually, but the optical cards cannot monitor the VC3 J1 string.
