traceroute

Description: 

Discovers the paths that router packets follow when traveling to their destinations. There is no no version.

Syntax: 

traceroute [ vrf vrfName ] destination [ ttl maxTTLCount ]
[ timeout timeOutVal ] [ data-size sizeValue ]
[ source { interface interfaceType interfaceSpecifier | address sourceAddress } ]
[ extended [ tos tosVal ] [ set-dont-fragment-bit ] [ interface iType iNumber ]

traceroute ipv6 [ vrf vrfName ] destination [ hop-limit hopLimit ] [ timeout timeOutVal ]
[ data-size sizeValue ] [ source { interface interfaceType interfaceSpecifier |
address sourceAddress } ] [ extended [ dscp trafficClass ] [ flow-label flowLabel ] ]

• vrfName—Name of the VRF context; string of 1–32 alphanumeric characters
• ipv6—Specifies the destination address as IPv6 format
• destination—IP address, IPv6 address, or domain name of the trace
• hopLimit—Maximum number of hops of the trace in the range 1–255; default value is 32
• maxTTLCount—Maximum number of hops of the trace in the range 1–255; default value is 32
• timeOutVal—Time in seconds to wait for trace responses in the range 1–20; default value is 2
• sizeValue—Number of bytes comprising the IP packet and reflected in the IP header in the range 0–64000
• source interface—Specifies an interface as the source for the transmitted packets

• interfaceType—Interface type; see Interface Types and Specifiers in About This Guide
• interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers in About This Guide

• source address—Specifies an IP address as source for the transmitted packets

• sourceAddress—IP address or domain name used as the source address

• extended—Specifies extended IP header attributes

• tosVal—Value of the ToS byte
• set-dont-fragment-bit—Specifies the don't-fragment bit
• iType—Interface type
• iNumber—Interface location
• trafficClass—Specifies the traffic class value to match in the Traffic Class field of each IPv6 packet header, in the range 1–255
• flowLabel—Specifies the flow label value to match in the Flow Label field of each IPv6 packet header, in the range 1–1048576
