# IOA Protocol Support

This appendix lists the layer 2 and layer 3 protocols and applications that IOAs support in combination with the listed LM. IOAs are identified by their physical labels. See Table 1 for a list of IOAs and their identifying labels.

The designation “not yet fully qualified” that appears in some tables in this appendix indicates that support for the protocol or application on the specified IOA has not yet been fully qualified by Juniper Networks. If you use a feature before it has been fully qualified, it is your responsibility to ensure that it operates correctly in your targeted configuration.

This appendix contains the following sections:

- Ethernet IOAs
- OCx/STMx ATM IOAs
- OCx/STMx POS IOAs
- Service IOA
