Release Notes for Cisco ONS 15454 Release 7.0.2
OL-11368-01
Caveats
UPSR Functionality
CSCee53579
Traffic hits can occur in an unprotected to UPSR topology upgrade in unidirectional routing. If you
create an unprotected circuit, then upgrade the unprotected circuit to a UPSR circuit using Unprotected
to UPSR wizard, selecting unidirectional routing in the wizard, the circuit will be upgraded to a UPSR
circuit. However, during the conversion, traffic hits on the order of 300 ms should be expected. This issue
will not be resolved.
Active Cross Connect (XC10G/XCVT) or TCC2/TCC2P Card Removal
As in BLSR and 1+1, you must perform a lockout on UPSR before removing an active cross connect or
TCC2/TCC2P card. The following rules apply to UPSR.
Active cross connect (XC10G/XCVT) cards should not generally be physically removed. If the active
cross connect or TCC2/TCC2P card must be removed, you can first perform an XCVT/XC10G side
switch or TCC2/TCC2P reset and then remove the card once it is in standby, or you can perform a lockout
on all circuits that originate from the node whose active cross connect card or active TCC2/TCC2P will
be removed (performing a lockout on all spans will also accomplish the same goal). No lockout is
necessary for switches initiated through CTC or through TL1.
Bridge and Roll
CSCsc60635
Bridge and Roll is allowed on the STM1E card, although it is not supported. This issue will be resolved
in Release 8.0.
Alarms
CSCsc66474
The ODU-Alarm indication signal is not sent downstream on a client when the line card is provisioned
as line terminated. This issue will not be resolved.
SNMP
CSCsc62801
For nodes configured in multishelf mode using the default LAN configuration, SNMP traps are not sent
to the management system. To avoid this issue, provision any the DCN-connected node as “Socks
proxy,” then, on such nodes add the following static route:
• Destination: 0.0.0.0
• Next hop: DCN Router
