Release Notes for Cisco ONS 15454 SDH Release 4.1.3

Caveats

DDTS # CSCdw38283

If a node has one good BITS reference and is running in a normal state, and you configure a second BITS

reference, then reconfigure the second reference within 30 seconds of applying the first configuration,

the node will enter FAST START SYNC mode. To avoid this problem, wait a minute before configuring

the second reference a second time. This issue is a hardware limitation, and there are no current plans to

resolve it.

DDTS # CSCdw23208

The following table summarizes B1, B2, and B3 error count reporting for SDH optical cards. Note that

not all reporting is done according to ITU specifications. In particular, ITU specifies error counts for B1

and B3 as the number of blocks with errors (refer to ITU-T G.826 for paths and ITU-T G.829 for RS and

MS).

DDTS # CSCdw82689

After creating 509 VLANs and provisioning many Ethernet circuits, Ethernet circuit provisioning can

become very slow, or possibly fail. Ethernet traffic may also incur an outage of a few minutes. To avoid

this problem, delete any VLANs that are created but not used, and do not recreate them. There is no

resolution planned for this issue.

DDTS # CSCdv10824: Netscape Plugins Directory

If you use CTC, JRE, and the Netscape browser with a Microsoft Windows platform, you must ensure

that any new installation of Netscape uses the same Netscape directory as the previous installation did,

if such an installation existed. If you install Netscape using a different path for the plugins directory, you

will need to reinstall JRE so that it can detect the new directory.

“Are you sure” Prompts

Whenever a proposed change occurs, the “Are you sure” dialog box appears to warn the user that the

action can change existing provisioning states or can cause traffic disruptions.
