Version Up Software Upgrade

Version Up Software Upgrade
The Version Up software upgrade feature allows users to independently upgrade ML-Series cards as part
of an overall software upgrade process. With this feature enabled, the user first upgrades all the cards in
the node that are not ML-Series cards, then in a second pass updates the ML-Series cards. Version Up is
disabled by default.
The user can initiate individual upgrades for each ML-Series card or upgrade all the ML-Series cards at
the same time. In the case of redundant ML-Series cards, individual upgrades allow time to verify the
proper operation of the first card before the second card is upgraded. No ML-Series cards are updated
until the user specifically requests it.
The user can perform a Version Up upgrade with CTC or Cisco Transport Manager (CTM). The Version
Up feature is only supported on the ONS 15454 and SDH platforms. TL1 does not support the Version
Up feature, and you cannot enter TL1 commands during the Version Up process.

Node and Card Behavior During Version Up

Between the upgrade of the non-ML-Series cards and the upgrade of the ML-Series cards, the node
functions normally with regards to existing circuits but does not allow new provisioning or software
downloads. Alarms still operate even with the ML-Series cards that are not yet upgraded.
The ML-Series card also continues to carry data traffic in the time span between the upgrade of the
non-ML-Series cards and the upgrade of the ML-Series card, although this traffic drops when the
ML-Series card resets to load the new software. You can telnet to the ML-Series card and configure the
card using the Cisco IOS CLI, but the new configuration only exists in the running configuration file and
cannot be saved to the startup configuration file.
During the Version Up upgrade, a SwMismatch condition appears for any cards running a different
software version, even for non-ML-Series cards awaiting their turn to reset. When the card resets and
loads the new software, the condition clears. The SwMismatch condition disappears on the ML-Series
cards as they finish resetting and loading the new software. You can use the SwMismatch condition to
keep track of ML-Series cards that still need upgrading. A SysBoot alarm is also raised during the
upgrade. This alarm does not clear until all the ML-Series cards are upgraded.

Enabling and Completing Version Up

The default software upgrade behavior for the node is fully automatic. To enable Version Up, the NE
defaults must be changed by a Superuser.
This procedure details enabling the Version Up feature through NE Defaults and completing the Version
Up process.
At the node view, click the Provisioning > Defaults tabs.
