Release Notes for Cisco ONS 15454 SDH Release 4.1.3

OL-4984-01

Caveats

DDTS # CSCea13593

DRI configuration rules require limits on multiple drops. However, in an ONS 15454 SDH DRI topology,

a unidirectional circuit can be created from one ring to another with two drops at the destination node.

This issue will be resolved in Release 5.0.

DDTS # CSCdz90733

PCA traffic can remain down after restoring the incorrect database and then restoring the correct

database to the node. To avoid this issue, exercise care in database restoration. If you accidentally restore

the wrong database, first restore the correct database and check to see if all traffic has returned. If PCA

traffic is still down, you may need to remove and reinsert a fiber or perform a cross connect card reset.

This issue will be resolved in Release 5.0.

DDTS # CSCdz84149

If a user is logged into CTC as a superuser (or other higher level security type), and then another

superuser changes the first user's security level to “retrieve” (or another lower level security type)

without first logging the user out, the lower level user is then still able to perform some actions

authorized only for the original login security level. For example, a “provisioning” level user demoted

to “retrieve” level in this manner can still provision and edit MS-SPRings (BLSRs) while logged into the

current session, though the same user may no longer provision DCCs. To ensure that a user's level is

changed completely, the superuser must log the user out prior to changing the security level. This issue

is under investigation.

DDTS # CSCdz90753

In the Maintenance > Cross Connect Resource Pane, the VT matrix port detail is inconsistent with the

general VT matrix data. This can occur when a 1+1 protection scheme is in place. To avoid confusion,

note that the VT matrix data counts the VTs for both the working and protect card, while the detail data

counts the VTs only for the working card. This issue is under investigation.

DDTS # CSCdz62367

When replacing a failed working E1-42 card in a 1:1 or 1:N protection configuration with the protect

card carrying the switched traffic, bit errors, less than 50ms in duration, are possible on the activated

protection card. This issue is currently under investigation.

DDTS # CSCdy10030

CVs are not positively adjusted after exiting a UAS state. When a transition has been made from counting

UAS, at least 10 seconds of non-SES must be counted to exit UAS. There are no plans to resolve this

issue at this time.

DDTS # CSCdx35561

CTC is unable to communicate with an ONS 15454 SDH that is connected via an Ethernet craft port.

CTC does, however, communicate over an SDCC link with an ONS 15454 SDH that is Ethernet

connected, yielding a slow connection. This situation occurs when multiple nodes are on a single

Ethernet segment and the nodes have different values for any of the following features:
