Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

Before You Begin
Ensure that you are configuring the correct interface; it must be an interface that is connnected to an end
station.
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Specifies an interface to configure, and enters interface
configuration mode.
switch(config)# interface type
slot/port
Step 2
Sets the interface to be an access host port, which
immediately moves to the spanning tree forwarding state
and disables port channeling on this interface.
switch(config-if)# switchport host
Step 3
Apply this command only to end
stations.
Note
This example shows how to set an interface as an Ethernet access host port with EtherChannel disabled:
switch# configure terminal
switch(config)# interface ethernet 1/10
switch(config-if)# switchport host
Configuring Trunk Ports
You can configure an Ethernet port as a trunk port; a trunk port transmits untagged packets for the native
VLAN plus encapsulated, tagged, packets for multiple VLANs.
Cisco NX-OS supports only 802.1Q encapsulation.Note
To configure a trunk port, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Specifies an interface to configure, and enters interface
configuration mode.
switch(config)# interface {type
slot/port | port-channel number}
Step 2
Sets the interface as an Ethernet trunk port. A trunk port can
carry traffic in one or more VLANs on the same physical
switch(config-if)# switchport
mode {access | trunk}
Step 3
link (VLANs are based on the trunk-allowed VLANs list).
By default, a trunk interface can carry traffic for all VLANs.
To specify that only certain VLANs are allowed on the
specified trunk, use the switchport trunk allowed vlan
command.
