Summarizes TCP, UDP, and RAW transport behavior, NSR session preservation, failover recovery, and TCP dump file inspection and conversion for troubleshooting.
Use this chapter to understand transport behavior, maintain supported sessions during failures, and examine TCP packet traces.
The chapter covers these transport protocol operations:
-
TCP, UDP, and RAW transport behavior for application and protocol traffic.
-
Nonstop routing (NSR) session preservation and failover recovery during supported route processor or process failures.
-
TCP packet trace storage, display, and conversion for troubleshooting.
Use the transport topics to compare protocol behavior, configure NSR recovery, review NSR restrictions, and convert or display TCP dump files.
TCP, UDP, and RAW transports
Explains the connection, delivery, and application characteristics of TCP, UDP, and RAW transports and identifies when their default settings are sufficient.
Nonstop routing for transport sessions
Explains how nonstop routing maintains supported routing protocol sessions during route processor failover by synchronizing application and transport state, and describes supported clients, failure handling, restrictions, and recovery behavior.
TCP dump file conversion
Explains how the TCP dump file converter supports troubleshooting by converting stored binary TCP packet traces into text or pcap format, and describes feature behavior, storage considerations, platform support, and available trace-viewing methods.
