You can modify attributes of a secondary ENI, but not the primary ENI, of an instance. You can modify the following attributes of an ENI:
- The name of the ENI.
- The security group associated with the ENI. One ENI must be associated with at least one security group. However, it cannot be associated with more than five security groups.
- Description of the ENI.
You can modify attributes of an ENI when it is in the Available or the Bound status. This document describes how to modify attributes of an ENI in the ECS console.
Before you modify attributes of an ENI, create an ENI.
