Figure 7-14: Creating the Receiving Site
3 Configure site authentication.
A local authentication password will be needed (it should match the incoming site’s remote password,
see Figure 7-11), and CHAP and/or PAP authentication should be enabled.
Figure 7-15: Configuring Site Authentication

7.6 Troubleshooting
The SCS event logging feature enables you to monitor network and user activity and troubleshoot
problems. Configure a destination for logging information using the Set/Define Logging command,
described on page 12-174.
To view PPP LCP and NCP negotiations with the remote host, use logging level 4 or 6. Level 4 logs PPP
negotiation activity, and is adequate for most PPP troubleshooting. Level 6 logs all PPP events; this is
generally only required to troubleshoot faulty PPP implementations.
