A new Interface Configuration scheme has been implemented in ACI version 5.2(7), 6.0(1) and later.
In the past, users had to manually create policies for IF Profile and IF Selector, but with the new method, users only need to assign a Policy Group to a physical port, and APIC will automatically create and assign a system-defined policy for IF Profile and IF Selector. The new system allows users to create and assign IF Profile, IF Profile, IF Selector, and IF Profile, IF Selector policies automatically.
As a result, users no longer need to create and manage IF Profiles and IF Selectors consciously.
Please refer to the following article for an overview of the new system and the procedure for creating a new configuration for a port.
ACI: Interface Configuration (version 6.0 or later)
This article explains what happens to the originally configured Interface Policy when upgrading from a previous version to version 5.2(7), 6.0(1) or later. This article explains what happens to the originally set Interface Policy when upgrading from a previous version to 5.2(7), 6.0(1) or later.
1. Support for Policies Set in Earlier Versions
The existing method (manual creation of IF Profile and IF Selector) is still supported in versions 5.2(7), 6.0(1), and later.
Policies created using the old method can be converted to the new method by performing a migration.
In this case, the IF Policy and IF Selector names will be automatically changed since a new system-defined policy will be created.Switch Profiles are also migrated to the system-defined policy in the same way.
2. migration method
Since there is a possibility that a momentary breakdown may occur at the timing of the migration, we ask that you perform the work during a time when the impact is minimal.
In the Fabric > Access Policies > Interface Configuration screen, you will see a message prompting you to migrate to the new method, as shown below, and click "migrate them" in the text.
Migration is performed on a node-by-node basis. The following selection screen is displayed. Check the target node and click "Save.
If only one of the nodes in a vPC pair is specified, the following warning message is displayed and rejected.
It can be confirmed that IF Profile and IF Selector have been changed as follows before and after migration.
IF Profile name: "LEAF1201_INT_PROF" -> "system-port-profile-node-1201"
IF Selector name: "E1-13" -> "system-port-selector-accportgrp-xxx_access_pg"
* " xxx_access_pg" is the Policy Group name
3. Changing the Interface description
In versions 5.2(7), 6.0(1) and later, it is no longer possible to change the Interface description from Fabric > Inventory, and a message appears on the Interface Configuration screen indicating that the configuration point has been changed.
Clicking Action > Edit Interface Configuration from the Interface Configuration screen will display a screen for changing the description, but if migration has not yet been performed, a message will appear alerting the user that migration will be performed if the settings are changed.
If you do not want to migrate, and would like to keep the previous configuration method, change the description of the Override policy.
(The description set from Fabric > Inventory was actually reflected in the Override policy and applied to the interface.)
The configuration is located at Fabric > Access Policies > Interfaces > Overrides.
If an existing policy does not exist, create a new one and set the interfaces to be associated with it.
