Initial Public Release
The Network Element (NE) with an earlier release is not visible, or is visible but can see the AR-XPE card while it preprovisions the cards. This is observed in one of these situations:
The network has a mixed release - one of the releases is Release 22.214.171.124 and other release is Release 9.6.0 or earlier.
A customer upgrades from Release 9.6.0 or earlier (such as Release 9.4.0 or 9.2.1) to Release 126.96.36.199, which results in the network state mentioned earlier in this section.
Cisco Transport Controller (CTC) Release 188.8.131.52 is expected to use a release specific driver (API) for NEs respectively. Due to a software bug, it incorrectly applies Release 184.108.40.206 drivers to earlier releases. This can lead to a variety of problems based on the release of the NE. Any provisioning activity on the node with an earlier release can cause issues that might result in the node going to an incorrect state. This might result in a non-deterministic behavior.
If CTC Release 220.127.116.11 is used, the NE with an earlier software release can observe one of the these potential problems:
The NE is not visible.
The NE is visible, but when you try to preprovision you can see the AR-XPE card which is supported in Release 18.104.22.168 and later.
One of these options can be used to work around this issue:
Upgrade all the nodes individually to Release 22.214.171.124. After this, CTC Release 126.96.36.199 can be launched without any issues.
If Cisco Prime Optical (CPO) is used to upgrade the network, CPO will not face this issue. However, do not provision with CTC Release 188.8.131.52 until all the nodes in the network are upgraded.
Use the earlier CTC release (Release 184.108.40.206 or earlier) in order to manage NEs with Release 9.6.0 or earlier.
A new CTC application will be made available on Cisco.com. Use this application instead of directly launching CTC from a browser in a network of mixed releases. The application will be available on Cisco.com by August 16, 2013.
