Chassis Management Interface

Chassis Management

The chassis uses the dedicated Management interface on the device. Multi-instance mode does not support using a data interface for chassis management or DHCP addressing for the Management interface.

You can only configure the chassis Management interface at the threat defense CLI (at initial setup) or FXOS CLI (after you convert to multi-instance mode). See Onboard the Multi-Instance Chassis for initial setup. See Change Chassis Management Settings at the FXOS CLI to change Management interface settings in multi-instance mode.

Note

By default, SSH is not allowed to this interface in multi-instance mode unless you enable the SSH server and an SSH access list. This difference means that you can connect to the application-mode threat defense Management interface using SSH, but after you convert to multi-instance mode, you can no longer connect using SSH by default. See Configure SSH and SSH Access List.

Instance Management

All instances share the chassis management interface, and each instance has its own IP address on the Management network. After you add the instance and specify the IP address, you can make changes to the network settings at the threat defense CLI.

The instance Management IP address allows SSH by default.
