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 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
