Cisco ASR 9000 Series Command Reference Guide

•
If specifying an Ethernet bundle interface, the range is from 1 through 65535.
For the subinterface argument, the range is from 0 through 4095.
To configure a large number of subinterfaces, we recommend entering all configuration data before you
commit the interface command.
To change an interface from Layer 2 to Layer 3 mode and back, you must delete the interface first and then
re-configure it in the appropriate mode.
A subinterface does not pass traffic without an assigned VLAN ID.Note

Examples
This example shows how to configure a VLAN subinterface on a 10-Gigabit Ethernet interface:
RP/0/RSP0/CPU0:router(config)# interface TenGigE 0/0/0/1.2
RP/0/RSP0/CPU0:router(config-subif)# dot1q vlan 1
RP/0/RSP0/CPU0:router(config-subif)# ipv4 address 50.0.0.1/24
This example shows how to create a VLAN subinterface with Layer 2 transport port mode enabled, and enter
Layer 2 transport configuration mode under that VLAN:
RP/0/RSP0/CPU0:router(config)# interface GigabitEthernet 0/4/0/1.1
RP/0/RSP0/CPU0:router(config-if-l2)#
