traceroute

This command performs a traceroute and displays the route (path) and packet transit delays across an IP network, for diagnostic purposes.

Syntax

traceroute {<IPv4 Address or Hostname>|ethernet|ipv6}

traceroute ethernet mpid <Endpoint Identifier> domain <Domain Name> 

traceroute  {ipv6 <IPv6 Address>|<IPv4 Address>} [max-ttl <Hop Limit>] [proto udp|icmp] [resolve-to-name]

traceroute {ipv6 <IPv6 Address>|<IPv4 Address>} source data {source-address interface <Interface Type> <Slot/Port/VLAN>|vrf <VRF Name> [max-ttl <Hop Limit>] [proto udp|icmp] [resolve-to-name]

traceroute {ipv6 <IPv6 Address>|<IPv4 Address>} source network-source <IP address alias or VRF> [proto udp|icmp]

Command	Description
IPv4 Address or Hostname	The IPv4 address or hostname to which the trace is sent.
source data source-address interface	Source interface, for example, gigabitethernet 0/0.
source data vrf	Source VRF name.
source network-source	Source network (alias or VRF).
max-ttl	Defines the maximum number of hops to the destination (1-30; default is 30).
proto {icmp|udp}	Defines the protocol type. The default is UDP. IPv4 traceroute also supports icmp protocol type.
resolve-to-name	If a DNS server has been configured, this option displays the FQDN of each node on the path to the destination (where possible). After entering this command option, no other options can be entered.

Note

■

Supports both IPv4 and IPv6 addresses.

■

In IPv4, it supports hostname resolution as well.

■

Sends three requests to each hop on the way to the destination.
