Usage Information
• If you assign an IP address to an interface, you cannot use this command to enable L2 switching — you must
first remove the IP address.
• The access parameter automatically adds an interface to default VLAN1 to transmit untagged traffic. Use
the switchport access vlan command to change the access VLAN assignment.
• The trunk parameter configures an interface to transmit tagged VLAN traffic. You must manually configure
VLAN membership for a trunk port with the switchport trunk allowed vlan command.
• Use the no switchport command to remove all L2 configurations when you configure an L3 mode
interface.
• Use the no switchport mode command to restore a trunk port on an interface to L2 Access mode on
VLAN1.
Example
OS10(conf-if-eth1/1/7)# switchport mode access

switchport trunk allowed vlan
Configures the tagged VLAN traffic that a L2 trunk interface can carry. An L2 trunk port has no tagged VLAN membership and does not
transmit tagged traffic.
Syntax
switchport trunk allowed vlan vlan-id-list
Parameters vlan-id-list — Enter the VLAN numbers of the tagged traffic that the L2 trunk port can carry. Comma-
separated and hyphenated VLAN number ranges are supported.
Default None
Command Mode INTERFACE
Usage Information Use the no version of this command to remove the configuration.
Example
OS10(conf-if-eth1/1/2)# switchport trunk allowed vlan 1000
OS10(conf-if-eth1/1/2)# no switchport trunk allowed vlan 1000

unit-provision
Provisions the unit ID of a Fabric Expander attached to an MX9116n Fabric Switching Engine in Full Switch mode.
Syntax
unit-provision node/unit-id provision_name
Syntax
unit-provision node/unit-id provision_name
Parameters
• node/unit-id — Enter 1 for node with an unassigned unit ID displayed in the show unit-provision
output.
• provision_name — Enter the service tag of the Fabric Expander displayed in the show discovered-
expanders output.
Default None
Command Mode CONFIGURATION
Usage Information
• To verify the currently configured mode on a Fabric Engine, use the show operating mode command. If a
Fabric Engine is in Full Switch mode, you must manually provision a Fabric Expander using the unit-
provision command. This command assigns a unit ID to a service tag or provision name. To transmit server
traffic, you must configure the virtual port on the Fabric Expander by entering the unit ID as the virtual-slot
number using the interface ethernet node/virtual-slot/port command.
