Software Features

Zero Touch Deployment

During switch installation, the IOS configuration files, the SW image, the IOx Application configuration and its running states are saved and persist on the SD Flash: card. The SDFlash: card can be inserted into an IE4000 to bring the switch up to an operational state with the same configuration.

Zero Touch Replacement

During switch replacement scenario, the IOS configuration files, the IOS SW image, the IOx Application configuration and its running states are saved and persist on the SD Flash: card. The SDFlash: card can be inserted into a replacement IE4000 to bring the new switch up to an operational state with the same configuration.

GUI support for IOx

The IE4000 Device Manager supports IOx networking configuration, Application Management, specifically, MTConnect Agent, as well as the capability to launch the Local Manager.

MTConnect Agent

The open source C++ for MTConnect Agent, version 1.3, is packaged to run on the IE4000’s IOx application hosting environment as a container. With the 512 MB RAM reserved for the application execution, the maximum number of MTConnect agents is 10.

Limitations and Restrictions

The IE4000 on-board flash: has only 128MB and the size of the SW tar image is approximately 110MB, the SD flash is the ONLY option to store any application related logs.

Description

Workaround

CSCva38680

If power is interrupted or the switch is reloaded from IOS, during the approximately 5 minutes it takes IOx (application and agents) to start, there is a risk of SDFlash card corruption.

Keep a backup of the SDFlash card contents and then if the issue occurs reformat the SDFlash card and restore the backup.

Different ip address should be assigned to vlan interface and IOx, but the switch does not display an error message if a same ip address is configured under vlan interface and IOx.

None

If you click on System info, in Local Manager, receive the following error: “Unable to get system health information.”

Click on System Info again.

Using the IOx Local Manager to install applications that take more than 30 min to download or activate will cause the browser session to timeout. However the process of downloading or activating will continue in the background and successfully complete.

Re-login to the LM will eventually reflect that success.

Currently the 30 min timeout is not configurable.

Log back into the IOx Local Manager and confirm the application is in Deployed or Activated state.
