Transition Networks SISPM1040-3xxx-L Web User Guide 25-2 Traceroute This page lets you issue ICMP, TCP, or UDP packets to diagnose network connectivity issues. Web Interface To start a Traceroute in the web interface: 1. Click Diagnostics and Traceroute. 2. Specify IP Address, Wait Time, Max TTL, and Probe Count. Figure 25-1: Traceroute 3. Click Start. Traceroute sends packets with gradually increasing TTL value, starting with TTL value of 1. The first router receives the packet, decrements the TTL value and drops the packet because it then has TTL value zero. The router sends an ICMP Time Exceeded message back to the source. The next set of packets are given a TTL value of 2, so the first router forwards the packets, but the second router drops them and replies with ICMP Time Exceeded. Proceeding in this way, traceroute uses the returned ICMP Time Exceeded messages to build a list of routers that packets traverse, until the destination is reached and returns an ICMP Echo Reply message. Parameter descriptions: Figure 25-2: Traceroute Output IP Address : The destination IP Address. Wait Time : Set the time (in seconds) to wait for a response to a probe (default 5.0 sec). Valid values are 1 - 60. 33763 Rev. G https://www.transition.com Page 404 of 496
