Release Notes for Cisco ONS 15454 SDH Release 4.1.3

OL-4984-01

Caveats

DDTS # CSCea02986

In MS-SPRing configurations multiple node deletions and additions on a ring in quick succession can

cause PCA traffic to go down. If this occurs, apply a Force Ring switch on the effected nodes. This issue

will be resolved in Release 5.0.

DDTS # CSCdz66275

When creating a MS-SPRing from the network view, the node default values for reversion are not

initially used. To see this, starting with no preferences file, log into a node with CTC, and set the node

default values for MS-SPRing reversion. Now, in Network view, use the MS-SPRing wizard to create a

MS-SPRing. The node level default values are initially ignored while the wizard is still in operation. If

you encounter this issue, you may need to change values as appropriate for your network while you are

still using the MS-SPRing wizard. Once the wizard is finished, these values are saved to a preferences

file and will be used henceforth. This issue will be resolved in a future release.

DDTS # CSCdz35479

Rarely, CTC Network view can freeze following the deletion or addition of a node from or to a

BLSR/MS-SPRing. This can result in the CTC Network view no longer updating correctly. If this occurs,

restart CTC. This issue will be resolved in Release 5.0.

DDTS # CSCdy63060

In a 4 node, two-fiber MS-SPRing configuration, the E100 unstitched circuit state can become stuck at

OOS-AINS-PARTIAL, even if there are no alarms and conditions raised.

This issue has been seen under the following conditions:

Step 1 Set up a 4 node, two-fiber MS-SPRing.

Step 2 Provision an E100 point to point circuit starting with the OOS-AINS state and the longer

Step 3 path as the working path. The working path should have at least one pass-through node.

Step 4 Ensure that Ethernet ports and STM-N ports are all in service, no alarms or conditions are raised, and

traffic is running clear.

If the state does not change automatically, use the Circuit Edit Window to explicitly set the circuit state

to IS. This issue will be resolved in a future release.

DDTS # CSCdy56668

Ethernet circuits may appear in the CTC circuit table with an INCOMPLETE status after an MS-SPRing

span is upgraded. The circuits, when this occurs, are not truly incomplete. They are unaffected and

continue to carry traffic. To see the circuit status correctly, restart CTC. This issue is under investigation.

DDTS # CSCdy48872

Issuing a lockout span in one direction while a ring switch (SF-R) is active in the other direction may

result in a failure to restore PCA circuits on the ring.
