traceroute Displays the routes that packets take to travel to an IP address. Syntax Parameters traceroute [vrf {management | vrf-name}] host [-46dFITnreAUDV] [-f first_ttl] [-g gate,...] [-i device] [-m max_ttl] [-N squeries] [-p port] [-t tos] [-l flow_label] [-w waittime] [-q nqueries] [-s src_addr] [-z sendwait] [-fwmark=num] host [packetlen] • vrf management- (Optional) Traces the route to an IP address in the management VRF instance. • vrf vrf-name - (Optional) Traces the route to an IP address in the specified VRF instance. • host - Enter the host to trace packets from. • -i interface - (Optional) Enter the IP address of the interface through which traceroute sends packets. By default, the interface is selected according to the routing table. • -m max_ttl - (Optional) Enter the maximum number of hops for the maximum time-to-live value that traceroute probes. The default is 30. • -p port - (Optional) Enter a destination port: ○ For UDP tracing, enter the destination port base that traceroute uses. The destination port number is incremented by each probe. ○ For ICMP tracing, enter the initial ICMP sequence value, incremented by each probe. ○ For TCP tracing, enter the constant destination port to connect. ○ -P protocol - (Optional) Use a raw packet of the specified protocol for traceroute. The default protocol is 253 (RFC 3692). ○ -s source_address - (Optional) Enter an alternative source address of one of the interfaces. By default, the address of the outgoing interface is used. ○ -q nqueries - (Optional) Enter the number of probe packets per hop. The default is 3. ○ -N squeries - (Optional) Enter the number of probe packets sent out simultaneously to accelerate traceroute. The default is 16. ○ -t tos - (Optional) For IPv4, enter the type of service (ToS) and precedence values to use. 16 sets a low delay; 8 sets a high throughput. ○ -UL - (Optional) Use UDPLITE for tracerouting. The default port is 53. ○ -w waittime - (Optional) Enter the time in seconds to wait for a response to a probe. The default is 5 seconds. ○ -z sendwait - (Optional) Enter the minimal time interval to wait between probes. The default is 0. A value greater than 10 specifies a number in milliseconds, otherwise it specifies a number of seconds. This option is useful when routers rate-limit ICMP messages. ○ --mtu - (Optional) Discovers the maximum transmission unit (MTU) from the path being traced. ○ --back - (Optional) Prints the number of backward hops when different from the forward direction. ○ host - (Required) Enter the name or IP address of the destination device. ○ packet_len - (Optional) Enter the total size of the probing packet. The default is 60 bytes for IPv4 and 80 for IPv6.
