Upgrading From Release 3.0 To Release 4.0 - Alcatel-Lucent 7210 SAS M OS Quality Of Service Manual

Overview

Upgrading from Release 3.0 to Release 4.0

User can use a release 3.0 config file and bootup with release 4.0. The system takes care of the
following automatically:
1. System executes the command "no ldp-use-local-fc-enable" and continues to operate with
release 3.0 behavior.
2. System changes user defined network policies present in the configuration file to use the new
release 4.0 policy commands and parameters. For every network policy, the system creates a
new mpls-lsp-exp-profile-map policy with same ID as the network policy ID and associates it
with the network policy (using the command mpls-lsp-exp-profile in the network policy
ingress context). User cannot modify this association with no ldp-use-local-fc-enable in use.
3. System sets the value of the use-global-mpls-lsp-exp-profile to the default mpls-lsp-exp-pro-
file-map policy "1". The user cannot modify it with no ldp-use-local-fc-enable in use.
4. User is all set to go. They can continue with release 3.0 behavior and continue to use the net-
work policies as before with the restrictions it imposes. It is highly recommended to use the
new behavior, as release 3.0 behavior will be deprecated in a future release.
5. User can execute the command `ldp-use-local-fc-enable' to use the flexibility provided by the
new policies. Please take a backup of the existing configuration file before this since once
this command is executed and user modifies the existing policies, they cannot use the com-
mand 'no ldp-use-local-fc-enable' (release 3.0 behavior) anymore.
