System Management 403The following example displays an address 180.50.1.1 which does not have connectivity.tracerouteThe traceroute User EXEC mode command discovers the routes that packets will actually take whentraveling to their destination.Syntax• traceroute ip-address |hostname [size packet_size] [ttl max-ttl] [count packet_count] [timeouttime_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 Localaddress (IPv6Z address), the outgoing interface name must be specified. Refer to the usageguidelines for the interface name syntax.• hostname — Hostname of the destination host. (Range: 1 - 158 characters)• size packet_size — Number of bytes in a packet. (Range: 40 - 1472)• ttl max-ttl — The largest TTL value that can be used. The traceroute command terminates whenthe destination is reached or when this value is reached. (Range:1 - 255)• count packet_count — The number of probes to be sent at each TTL level. (Range:1 - 10)• timeout time_out — The number of seconds to wait for a response to a probe packet. (Range: 1 - 60)• source ip-address — One of the interface addresses of the device to use as a source address for theprobes. The device will normally pick what it feels is the best source address to use. (Range: ValidIP Address)• tos tos — The Type-Of-Service byte in the IP Header of the packet. (Range: 0 - 255)Default Configurationsize packet_size — The default is 40 bytes.ttl max-ttl — The default is 30.Console# ping 180.50.1.1Pinging 180.50.1.1 with 56 bytes of data:PING: net-unreachablePING: net-unreachablePING: net-unreachable5400_CLI.book Page 403 Wednesday, December 17, 2008 4:33 PM
