Release Notes for Cisco ONS 15454 Release 7.0.2
OL-11368-01
Resolved Caveats for Release 7.0.x
Create the DS3XM-12 conversion circuit again as before. The DS-1 portless port lines do not transition
to IS.
To recover from this issue, change the DS-3 port state to OOS_MT and then to IS. The DS-1 portless
port lines will transition properly. This issue is resolved in Release 7.0.
Data IO Cards
CSCin96350
If L2 protocol tunneling is disabled on an interface when it is not a member of a bridgegroup, this can
cause the CAM programming of STP MAC addresses to be incorrect. The spanning tree received on a
node is not passed on to the host, and the spanning tree process might not converge due to the STP
packets failing to reach the host. If this occurs, add the affected interface to a bridgegroup and disable
protocol tunneling. This issue is resolved in Release 7.0.
CSCsb40206
In Asymmetric configuration, with autonegotiation enabled and flow control selected, an ML-series card
might fail to synchronize with, or to recognize the asymmetric flow control. This issue is resolved in
Release 7.0.
CSCeg15044
IOS does not allow telnet connections when there are simultaneous Telnet requests, even though there
might be unused tty lines available. If this issue occurs, a “No Free TTYs error” message is displayed.
This issue is resolved in Release 7.0 (and 6.0).
DWDM Cards

The OPT-BST amplifier card is in a LASER OFF state, even if input power is provided to all input ports.
This issue only occurs with Release 7.0 and can be reproduced on a card with the amplifier turned on,
in operating conditions (with lasers on) as follows.
Step 1 From the card-level Maintenance tab set ALS Mode to Manual Restart and click Apply.
Step 2 Set OSRI to ON and click Apply. The amplifier turns off.
Step 3 Set OSRI to OFF and click Apply. The amplifier stays turned off (this is expected, since in Manual
Restart the lasers are turned back on by means of a Request Laser Restart command issued in CTC).
Step 4 Select the Request Laser Restart check box in the Maintenance tab and click Apply.
The amplifier goes into APR for 9 seconds (correct), but after this it turns off; it should go into LASER
ON state (State 4 at module level). If this issue occurs, change the card from manual restart to auto
restart, then toggle OSRI ON and OFF. This issue is resolved in Release 7.0.2.
