Traceroute

Traceroute discovers the IP routes along which packets were forwarded by sending an IP packet to the target host and back to the switch. The Traceroute page shows each hop between the switch and a target host, and the round-trip time to each such stop.

  1. Click Administration > Traceroute. The Traceroute page opens.
  2. Configure Traceroute by entering the fields:
    • Host Definition--Select whether hosts will be identified by their IP address or name.
    • IP Version--If the host will be identified by its IP address, select either IPv4 or IPv6 to indicate that it will be entered in the selected format.
    • IPv6 Address Type--Select Link Local or Global as the type of IPv6 address to enter.
      • Link Local--The IPv6 address uniquely identifies hosts on a single network link. A link local address has a prefix of FE80, is not routable, and can be used for communication only on the local network. Only one link local address is supported. If a link local address exists on the interface, this entry replaces the address in the configuration.
      • Global--The IPv6 address is a global Unicast IPV6 type that is visible and reachable from other networks.
    • Link Local Interface--If the IPv6 address type is Link Local, select from where it is received.
    • Host IP Address/Name--Enter the host address or name.
    • TTL--Enter the maximum number of stops that Traceroute permits. This is used to prevent a case where the sent frame gets into an endless loop. The Traceroute command terminates when the destination is reached or when this value is reached. To use the default value (30) select Use Default.
    • Timeout--Enter the length of time that the system waits for a frame to return before declaring it lost or select Use Default.
  3. Click Activate Traceroute. The operation is performed.
  4. A page is displayed showing the Round Trip Time (RTT) and status for each trip in the fields:

    • Index--Displays the number of the hop.
    • Host--Displays a stop along the route to the destination.
    • Round Trip Time (1-3)--Displays the round trip time in (ms) for the 1-3rd frame and the status of the 1-3rd operation.
