Dell EMC SmartFabric OS10 User Guide Release 10.5.0

• 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.
