describe_network_interfaces

EC2.Client.describe_network_interfaces(**kwargs)

Describes one or more of your network interfaces.

If you have a large number of network interfaces, the operation fails unless you use pagination or one of the following filters: group-id, mac-address, private-dns-name, private-ip-address, private-dns-name, subnet-id, or vpc-id.

      The name of the filter. Filter names are case-sensitive.

    • Values (list) –

      The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR, and the request returns all results that match any of the specified values.

      • (string) –

• DryRun (boolean) – Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  Default: Describes all your network interfaces.

  • (string) –

• NextToken (string) – The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.

• MaxResults (integer) – The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output.
