Gigabit Ethernet Management Interface Overview

• Run the setup command facility again, and create another configuration:
• Modify the existing configuration or configure additional features by using the CLI:
Gigabit Ethernet Management Interface Overview
The controller provides an Ethernet management port named GigabitEthernet0.
The purpose of this interface is to allow users to perform management tasks on the controller; it is an interface
that should not, and often cannot, forward network traffic, but can be used to access the controller through
Telnet and SSH to perform management tasks on the controller. The interface is most useful in troubleshooting
scenarios when other forwarding interfaces are inactive.
The following aspects of the management Ethernet interface should be noted:
• The controller has one management Ethernet interface named GigabitEthernet0.
• IPv4, IPv6, and ARP are the only routed protocols supported for the interface.
• The interface provides a way to access the controller even if forwarding interfaces are not functional, or
• The management Ethernet interface is part of its own VRF. See the Cisco Catalyst 9800 Series Wireless

Default Gigabit Ethernet Configuration

By default, a forwarding VRF is configured for the interface with a special group named Mgmt-intf. This
cannot be changed. This isolates the traffic on the management interface away from the forwarding plane.
Otherwise, the interface can be configured like other Gigabit Ethernet interfaces for most functions.
For example, the default configuration is as follows:
interface GigabitEthernet0
vrf forwarding Mgmt-intf
ip address 200.165.200.225 255.255.255.224
negotiation auto

controller.
