Pppd-305 〈Limited〉

I’m unable to find a verified or widely recognized product, standard, or system specifically called in public technical documentation (e.g., RFCs, Linux man pages, IEEE standards, or common PPP daemon references).

However, I can provide a based on likely interpretations: If “pppd-305” refers to a custom PPP daemon (pppd) variant or bug ID : Feature Suggestion: Adaptive LCP Echo Failure Recovery Problem it solves: In some PPP links (especially over unstable transports like LTE, satellite, or VPN tunnels), pppd may drop the connection after a few missed LCP echo replies, even if traffic is still flowing. This causes unnecessary reconnections. pppd-305

lcp-traffic-adaptive 5 # wait 5 missed echoes only if no traffic lcp-adaptive-threshold 30000 # 30 seconds of no traffic + no echo = fail Reduces false link failures on lossy but still functional connections. If “pppd-305” is a product or device model : Please provide more context (e.g., manufacturer, log snippet, or use case) and I’ll tailor a more specific, helpful feature.

“Traffic-Triggered LCP Liveness” Instead of relying only on LCP echo requests/responses, the daemon monitors actual payload traffic. If bidirectional data is seen within the last N seconds , LCP echo failures are ignored (or tolerated longer). Only when both traffic and LCP echo replies stop does it tear down the link. Example configuration addition: lcp-traffic-adaptive 5 # wait 5 missed echoes only
