Cisco Catalyst 9800-80 - Default Gigabit Ethernet Configuration; Configuring Gigabit Ethernet Interfaces

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 Cisco IOS is down.
• The management Ethernet interface is part of its own VRF. See the Cisco Catalyst 9800 Series Wireless
Controller Software Configuration Guide for more details.
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
Configuring Gigabit Ethernet Interfaces
This section shows how to assign an IP address and interface description to an Ethernet interface on your
controller.
For comprehensive configuration information on Gigabit Ethernet interfaces, see the Configuring LAN
Interfaces chapter of the Cisco IOS Interface and Hardware Component Configuration Guide.
For information on the interface numbering, see the Cisco Catalyst 9800 Series Wireless Controller Software
Configuration Guide.
For comprehensive configuration information about IP routing and IP routing protocols, see the Configuring
IP Routing Protocol-Independent Feature on cisco.com.
