Configuration Examples
Configuring a FEX with a Layer 3 Host Interface
This example shows how to configure a Fabric Extender with a Layer 3 host interface (at the interface level,
subinterface level, port channel level, and port channel subinterface level):
Layer 3 Configuration
config t
interface ethernet 101/1/1
no switchport
ip address 192.0.1.1/24
Mtu 9000
no shutdown
Layer 3 Host Interface Port Channel Configuration
config t
interface ethernet 101/1/1-2
no switchport
channel-group 12
no shutdown
interface port-channel 12
ip address 192.0.3.1/24
mtu 2000
no shutdown
The VLAN used in the Layer 3 host interface (HIF) or host interface port channel (HIFPC) subinterface
Note
has only local significance to its parent interface. The same VLAN ID can be reused between Layer 3
subinterfaces in the same switch or VDC.
Configuring a Host Interface in a vPC Topology Connected to Two FEXs
This example shows how to configure a host vPC with a FEX (host vPC attached to 2 different FEXs):
Switch 1 Configuration
config t
feature lacp
int e101/1/1-2
channel-group 12 mode active
no shutdown
Int port-channel10
switchport
switchport mode trunk
switchport trunk allowed vlan 1-20
vpc 10
