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

In one rare case, the ONS 15454/15327 times out a user session without communicating the timeout to 
TL1. If this happens, the TL1 user remains logged in, although the session is actually timed out. This 
can occur when you log into the node with a timeout of X minutes. If the user session sits idle for all but 
5 seconds of the X minutes, then you have only 5 seconds to type in a command to notify the node that 
the session is active. If you try this, you will likely miss the five second window, in which case the node 
will respond as though the session is inactive and deny access. However, because you have typed a key, 
irrespective of the five second window, TL1 responds as though the session is active and does not log 
you out (time out). You will not have access to the node and will receive a “DENY” response to TL1 
commands. The error message may vary depending on commands issued. To recover from this situation, 
log out and log back in to TL1. This issue is resolved in Release 4.6.

Release 4.1 and 4.5 TL1 cannot display/retrieve/delete a DS3Xm VT Non-STS-1 
cross-connection/circuit. This applies to ONS 15454s with DS3XM VT cross-connection provisioning 
via TL1, on any STS or port other than STS-1 or PORT-1, and with the AID format of:

VT1-Slot#-Sts#-Group#-Vt#

The cross-connection is provisioned as expected; however, the connection STS number in the TL1 VT 
AID format is always shown as “1” for the RTRV-CRS::ALL command and RTRV-CRS-VT1 with the 
AID used in the creation command (the non-one STS).

This issue has an impact on any DS3Xm VT connection deletion via TL1 where the STS number is not 
actually 1. The displayed VT1 AID cannot be used to retrieve the connection, and also cannot be used 
to delete the created connection. Also, the VT alarms/events/conditions on such a DS3XM VT 
circuit/connection will have the same AID issue: the StsNumber in the AID is always 1.

To work around this issue, delete the TL1-created DS3XM VT non-STS-1 cross-connection using the 
provisioned DS3XM VT AID (non-STS-1) or using CTC. There is no workaround for the alarm/event 
reporting for the non-STS-1 DS3XM VT circuit in the impacted releases (4.1 and 4.5). This issue is 
resolved in Release 4.6 and in maintenance Release 4.1.3.

This section highlights new features and functionality for Release 4.6.x. For detailed documentation of 
each of these features, consult the user documentation.

The FC_MR-4 (Fibre Channel 4-port) card uses pluggable Gigabit Interface Converters (GBICs) to 
transport non-SONET/SDH-framed, block-coded protocols over SONET/SDH in virtually concatenated 
or contiguously concatenated payloads. The FC_MR-4 can transport Fibre Channel over SONET/SDH 
using Fibre-Channel client interfaces and allows transport of one of the following at a time:
