Cisco Cisco ONS 15454 SONET Multiservice Provisioning Platform (MSPP) Notas de publicación

In a configuration with OC-48 Any Slot cards and an STS-24c circuit, provisioned between G1000-4 
cards with traffic going over the OC-48 span, extracting the G1000-4 card at one end of the STS-24c 
circuit before deleting the circuit will result in a traffic hit on all existing SONET circuits defined over 
that same span. This only occurs when the STS-24c is provisioned on timeslot 25.

In the Cisco ONS 15454 Procedure Guide, Release 4.1.x, refer to the “NTP-77 Delete Circuits” 
procedure to delete the 24c circuit before removing the card. Once you have deleted the circuit, refer to 
the “DLP-191 Delete a Card from CTC” task (also in the procedure guide) to delete the G1000-4 card. 
This issue will be resolved in Release 5.0.

CTC SendPDIP alerts might be raised on upgrades if any of the nodes in your network have the flag for 
SendPDIP set to “false” in their associated NE Defaults. This is because the upgraded node will have the 
value set to “true,” which is the default setting. You do not need to clear these alerts. They will clear 
when the upgrade is finished. 

Rarely, when the active TCC2 is removed, small traffic errors of 2 to 30 ms can sometimes occur. To 
avoid this issue, switch to the protect TCC2 before removing the working TCC2.

When DHCP forwarding is turned on, and the forwarding to address is set to a cellbus address instead 
of a DHCP server address, you can lose connection to your nodes. Always set the forwarding address to 
a DHCP server. This issue will be resolved in a future release.

While the DS3E protect card is active, invoking the auto frame format provisioning feature (AUTL) for 
a port might result in a misprovisioned frame format on that port (as compared to the actual frame format 
received on the DS3 receive line). If you must provision the frame format for a port while the protect 
card is active, provision it explicitly (manually select UNFRAMED, M13 or CBIT) instead of using the 
AUTL feature to ensure appropriate frame format provisioning on that port. This issue will be resolved 
in a future release.

Rarely, loss of traffic on an EC1 card can occur if you pull the card and quickly reinsert it. To avoid this 
issue, wait 5 seconds before reinstalling the card. This issue will be resolved in a future hardware release.
