Configure a Subinterface

You can add up to 500 subinterfaces to your chassis.

VLAN IDs per interface must be unique, and within an instance, VLAN IDs must be unique across all assigned interfaces. You can reuse VLAN IDs on separate interfaces as long as they are assigned to different instances. However, each subinterface still counts towards the limit even though it uses the same ID.

This section discusses FXOS VLAN subinterfaces only. You can separately create subinterfaces within the instance. See Chassis Interfaces vs. Instance Interfaces.
