Traceroute
Traceroute discovers the IP routes along which packets were forwarded by
sending an IP packet to the target host and back to the device. The Traceroute
page shows each hop between the device and a target host, and the round-trip
time to each such hop.
STEP 1
Click Administration > Traceroute .
STEP 2
Configure Traceroute by entering information into the following fields:
• Host Definition —Select whether hosts are identified by their IP address or
name.
• IP Version —If the host is 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 hops 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 .
STEP 3
Click Activate Traceroute . The operation is performed.
