Configuring an Ethernet subinterface
When you configure an Ethernet subinterface, follow these restrictions and guidelines:
•
To transmit and receive packets through an Ethernet subinterface, you must associate it with a VLAN.
For more information, see
Layer 2—LAN Switching Configuration Guide
.
•
To transmit packets between a local Ethernet subinterface and a remote Ethernet subinterface,
configure them with the same subinterface number and VLAN ID.
