| Certification Program Name: | PPP Multilink Operation |
| Certification Program ID: | 10727 |
| Certification Program Category: | Cisco Interoperability - Link Protocols |
| Description: | This certification verifies that the device under test can communicate with the Cisco 175x-class router using PPP Multilink (RFC 1990). Use of an authentication protocol is optional. (The 1751 is assumed to have code interoperable with other Cisco devices.) |
| Interpretation: | Devices earning this certification have demonstrated the ability to participate in a WAN network using Multilink PPP to communicate directly with a Cisco router across the WAN interface. |
| Product Applicability: | This certification is applicable to all devices implementing a synchronous or asynchronous WAN interface. |
| Testing Overview: | The Tolly Group will configure both the SUT and the Cisco router serial (WAN) interfaces for PPP with no authentication. Engineers will verify that both devices show link and protocol "up" and that data traffic can traverse the link. (The successful execution of a "ping" command will suffice.) |
