Security
Security features are supported on the I/O Aggregator.
This chapter describes several ways to provide access security to the Dell Networking system.
For details about all the commands described in this chapter, refer to the Security chapter in the Dell
PowerEdge FN I/O Aggregator Command Line Reference Guide.
Understanding Banner Settings
This functionality is supported on the I/O Aggregator.
A banner is a note that is displayed when you log in to the system, depending on the privilege level and
the command mode into which the you log in. You can specify different banners to be displayed as the
message-of-the-day (MOTD), as the opening quote in EXEC mode, or as the beginning message in EXEC
Privilege mode. Setting up a banner enables you to display any important information or group-level
notification that needs to be communicated to all the users of the system.
A login banner message is displayed only in EXEC Privilege mode after entering the enable command
followed by the password. These banners are not displayed to users in EXEC mode. When you connect to
a system, the message-of-the-day (MOTD) banner is displayed first, followed by the login banner and
prompts. After you log in to the system with valid authentication credentials, the EXEC banner is shown.
You can use the MOTD banner to alert users of critical upcoming events so that they can plan and
schedule their accessibility to the device. You can modify the banner messages depending on the
requirements or conditions.
Accessing the I/O Aggregator Using the CMC Console
Only
This functionality is supported on the I/O Aggregator.
You can enable the option to access and administer an I/O Aggregator only using the chassis
management controller (CMC) interface, and prevent the usage of the CLI interface of the device to
configure and monitor settings. You can configure the restrict-access session command to disable
access of the I/O Aggregator using a Telnet or SSH session; the device is accessible only using the CMC
GUI. You can use the no version of this command to reactivate the Telnet or SSH session capability for
the device. Use the show restrict-access command to view whether the access to a device using Telnet
or SSH is disabled or not.
