Fa1 Interface and mgmtVrf

Caution The Ethernet management port is intended for out-of-band access only. Like the console port, the
Ethernet management port has direct access to critical resources on the switch. Connecting this port to
an in-band network might cause performance degradation and vulnerability to a denial of service attack.
A service-policy that is applied to the control-plane interface is not applicable to traffic incoming on the
Note
management port.
All features that use fa1 now need to be VRF-aware.
You cannot configure any other interface in the same routing domain and you cannot configure a
Note
different routing domain for the Fa1 interface.
On bootup the fa1 port assumes the following default configuration.
Images prior to Cisco IOS XE 3.4.0SG/15.1(2)SG use the old VRF definition format for management VRF as shown below.
