LCP Up/Down

Informational

LCP is used by PPP to initiate and manage sessions. LCP is responsible for the initial establishment of the link, the configuration of the session, the maintenance of the session while in use, and the termination of the link. LCP is considered Up when the link is being established and configured, and is considered down once the session is fully established and passing traffic. LCP then comes up to pass Link Maintenance packets during the session, and goes down after the maintenance is complete. LCP comes up when a termination request is sent, and goes down when the link is terminated.

IPCP IP reject

Warning

This message is generated when IPCP attempts to define the IP characteristics for a PPP session, but does not have the IP address of the local interface to define the session. Without IP address information on both sides of the session, the PPP session cannot begin passing IP traffic.

Troubleshooting steps:

• Check Dialer interface configuration to ensure an IP address is configured, either as a static address or through Dynamic IP addressing or through IP unnumbered.
