3Com Switch 4500 Family - Tracert

2-3
0% packet loss
round-trip min/avg/max = 1/2/3 ms
The above output information indicates that the destination host is reachable. Each probe packet from
the source device has got a reply, with the minimum/average/maximum packet roundtrip time being
1ms/2ms/3ms.

Parameters
-a source-ip: Specifies the source interface IP address used by this command.
-f first-ttl: Specifies the initial TTL value of the packets to be sent, so as to only display the addresses of
those gateways on the path whose hop counts are not smaller than the hop count specified by the
first-ttl argument. For example, if the first-ttl argument is 3, the command displays the addresses of the
gateways from the third hop. The first-ttl argument ranges from 1 to 255 and defaults to 1.
-m max-ttl: Specifies the maximum TTL value of the packets to be sent. After the command sends a
packet with the maximum TTL, it will not send any more packets. With this argument, this command
only displays the addresses of those gateways from the source address to hop according to the hop
count specified by the argument. For example, if the max-ttl argument is 5, the command displays the
addresses of the gateways from the source to the fifth hop. The max-ttl argument ranges from 1 to 255
and defaults to 30.
-p port: Specifies the destination port of the packets to be sent. The port argument ranges from 0 to
65535 and defaults to 33434. Generally, you need not change the argument.
-q num-packet: Specifies the number of packets to be sent each time. The num-packet argument
ranges from 0 to 65,535 and defaults to 3.
-w timeout: Specifies the timeout time to wait for ICMP error packets. The timeout argument ranges
from 0 to 65,535 and defaults to 5,000 (in milliseconds).
string: Host name of the destination host, in the range of 1 to 20 characters.
The tracert command also supports the ipv6 keyword. For details, refer to IPv6 Management
Command.
Description
Use the tracert command to trace the gateways that the test packets pass through from the source
device to the destination device. This command is mainly used to check the network connectivity and
help locate the network faults.
