You can configure the link mode and MDI/MDIX settings for the management interface from the
appliance editor. You must configure all other management interface settings, such as IPv4 address, IPv6
address, and DNS settings locally on the device.

Caution

Changing the maximum transmission unit (MTU) interrupts traffic on the device. The range within
which you can set the MTU can vary depending on the FireSIGHT System device model and interface
type. See

Configuring the Sensing Interface MTU, page 6-63

for more information.

To configure the management interface:

Access:
