Link Flags

The Link flags field, which provides information about the physical link, displays one or more of the following values:

• ACFC—Address control field compression is configured. The Point-to-Point Protocol (PPP) session negotiates the ACFC option.
• Give-Up—Link protocol does not continue connection attempts after repeated failures.
• Loose-LCP—PPP does not use Link Control Protocol (LCP) to indicate whether the link protocol is operational.
• Loose-LMI—Frame Relay does not use the Local Management Interface (LMI) to indicate whether the link protocol is operational.
• Loose-NCP—PPP does not use the Network Control Protocol (NCP) to indicate whether the device is operational.
• No-Keepalives—Link protocol keepalives are disabled.
• PFC—Protocol field compression is configured. The PPP session negotiates the PFC option.
