traceroute
The traceroute User EXEC mode command discovers routes that packets actually take when
traveling to their destination.
Syntax
• traceroute ip-address | hostname [ size packet_size ] [ ttl max-ttl ] [ count packet_count ] [ timeout
time_out ] [ source ip-address ] [ tos tos ]
•
traceroute ipv6 { ipv6-address | hostname } [ size packet_size ] [ ttl max-ttl ] [ count packet_count ]
[
timeout time_out ] [ source ip-address ] [ tos tos ]
•
ipv6 — IPv6 checks the network connectivity.
•
ip4-address — Destination host IPv4 address. (Range: Valid IP Address)
•
ip6-address — Unicast or multicast IPv6 address to ping. When the IPv6 address is a Link
Local address (IPv6Z address), the outgoing interface name must be specified. Refer to the
usage guidelines for the interface name syntax.
•
hostname — Host name of the destination host. (Range: 1 - 158 characters)
•
packet_size — Number of bytes in a packet. (Range: 40 - 1500)
•
max-ttl — The largest TTL value that can be used. The traceroute command terminates
when the destination is reached or when this value is reached. (Range: 1 - 255)
•
packet_count — The number of probes to be sent at each TTL level. (Range: 1 - 10)
•
time_out — The number of seconds to wait for a response to a probe packet.
(Range: 1 - 60)
