New Features

Extreme Fabric Automation 2.4.2 provides the following enhancements.

Table 1. Features and improvements
Feature	Description
Journal clearing	New options for the efa-journal clear command let you clear journal entries by state: pending, failed, completed, processing, all. For more information, see the command topic in the Extreme Fabric Automation OpenStack Integration Guide.
Journal health	Output for the efa-health show and efa-health show --advanced commands now provides information about journal health: journal size, size threshold, whether the size exceeds the threshold, and whether the status is up or down. For more information, see the command topic in the Extreme Fabric Automation OpenStack Integration Guide.
L3 IP MTU	New support for the `ip-mtu` option at the network level. For more information, see the "Layer 3 IP MTU" topic in the Extreme Fabric Automation OpenStack Integration Guide.
Mechanism driver and L3 service plug-in	The `extreme_efa_v2` and `extreme_l3_efa_v2` plug-ins now use the journaling mechanism. You can use the previous plug-ins to enable non-journaling. For more information, see the following topics in the Extreme Fabric Automation OpenStack Integration Guide. Mechanism Driver and Plug-ins Enable the Non-Journal Plug-in
L3 flavor configuration	Configuration command examples are updated. For more information, see the "L3 Flavors" topic in the Extreme Fabric Automation OpenStack Integration Guide.
L3 routers	Support for creating routers in distributed mode is disabled. For more information, see the "L2 Routers" topic in the Extreme Fabric Automation OpenStack Integration Guide.
Multiple management IP networks	You can add management routes in multi-node deployments during installation and upgrade. You can also use the CLI to create, delete, and show these management routes. For more information, see the following guides: Extreme Fabric Automation Command Line Reference for syntax and examples of the efa mgmt route create, efa mgmt route delete, and efa mgmt route show commands Extreme Fabric Automation Administration Guide for the new "Add and Delete Management Routes" topic Extreme Fabric Automation Deployment Guide for revised multi-node installation and upgrade topics
MTU for endpoint groups	You can configure the value for the maximum transmission unit when you create or update an endpoint group. Use the `--ip-mtu` parameter (in the format `ctag:value`) to configure the MTU for the tenant network. This value is then configured on the interface VE on the SLX device. To configure MTU when you create an endpoint group, run the efa tenant epg create command. To configure MTU for an existing endpoint group, run the efa tenant epg update command during `vrf-add` or `ctag-range-add` operations. For more information, see the following guides: Extreme Fabric Automation Command Line Reference for syntax and examples of the commands Extreme Fabric Automation Administration Guide for the new "Configure MTU for an Endpoint Group" topic Note: During upgrade from EFA 2.4.1 to 2.4.2, any MTU value configured explicitly on the interface VE remains intact on the SLX device after upgrade.
