Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

Configure

In this section, you are presented with the information to configure the features described in this document.

Note: Although not shown in the diagram above, clocking needs to be supplied by the DCE. The easiest way to do this is by using a Cisco DCE cable at the router side and issuing the clockrate configuration command. For simplicity, IP routing, WAN configurations, SDLC addresses and other SDLC-specific configurations are not shown above. This configuration highlights how STUN can be used in mixed encapsulation.
