Release Notes for Cisco ONS 15454 SDH Release 4.1.3
OL-4984-01
Resolved Caveats for Release 4.1.3
the characters from 5th position onwards. While node was operating in release 4.1.3, create the users
with 'A' at 5th position of the username. Upgrade the node to any other release. After the upgrade, only
the first 4 characters are retained as username. This issue is serious enough to cause a network to be
unreachable during an outage or other service impacting occasions.
Workaround: Do not add a username with character 'A' in 5th position. This issue is fixed in Release 5.0.
DDTS # CSCeb84342
Occasionally, after both power sources are removed and plugged in with one power source (Battery A),
the node reboots but does not raise PWR-B alarms. To correct this, remove PWR-B and plug it back.
This issue is resolved in Releases 4.6 and 4.1.3.
DDTS # CSCec20521
After addition and deletion of a static route that overlaps with the internal IP addresses range, all cards
in the shelf reboot. This can also happen after the node learns a similar route through OSPF or RIP
updates. This issue is present in all releases through 4.1 and 4.5. To avoid this issue, do not provision
static routes with a destination address in the subnet range 192.168.190.x, and avoid overlap between IP
addresses in the network and the internal subnet range 192.168.190.x. If the issue does occur, reset your
TCCs. This issue is resolved in Release 4.6 and in maintenance Release 4.1.3.
DDTS # CSCec16812
UNEQ-V alarms are incorrectly raised prior to connecting a TAP to a TACC, and also after disconnecting
the TAP from the TACC. This issue is resolved in Releases 4.1.3 and 4.6.
DDTS # CSCea19297
For any STS or VT circuit that terminates on a node, an AIS (path level) that raises and clears on that
circuit's path may result in an inability of other path alarms to be cleared. This can also occur when a
line-level alarm occurs on the circuit path's line, causing the OC-N to send AIS-path downstream on each
path within the line. This issue is resolved in Release 4.1.
DDTS # CSCea21686
Retrieving a diagnostic file may cause a Standby or Active TCC2 reset. This is not traffic affecting. This
issue is resolved in Release 4.1.
MS-SPRing Functionality
DDTS # CSCdy65890
If you have PCA circuits over two-fiber or four-fiber MS-SPRing protect channels, an incorrect
auto-inservice transition occurs after traffic preemption. You may place the circuit back into the
OOS-AINS state after the BLSR has returned to the unswitched mode, using the Circuit Editing pane of
the CTC. This issue is resolved in Release 4.1.
