Network Diagnostics

S- K- and 7100-Series network diagnostics provide for:

• Pinging another node on the network to determine its availability
• Performing a traceroute through the IP network to display a hop-by-hop path from the device to a specific destination host
• Querying name servers to translate hostnames to IP addresses or IP addresses to hostnames

Use the ping command, in any command mode, to determine whether the specified node is available.

System(rw)->ping -c 10 127.0.0.1
PING 127.0.0.1 (localhost) 64 bytes of data.
64 bytes from 127.0.0.1 (localhost): icmp_seq=0 ttl=64 time=1.58 ms
64 bytes from 127.0.0.1 (localhost): icmp_seq=1 ttl=64 time=1.52 ms
64 bytes from 127.0.0.1 (localhost): icmp_seq=2 ttl=64 time=1.57 ms
64 bytes from 127.0.0.1 (localhost): icmp_seq=3 ttl=64 time=2.26 ms
64 bytes from 127.0.0.1 (localhost): icmp_seq=4 ttl=64 time=1.42 ms

Use the traceroute command, in any command mode, to display a hop‐by‐hop path through an IP network from the device to a specific destination host.

System(rw)->traceroute 192.167.252.17
traceroute to 192.167.252.17 (192.167.252.17), 30 hops max, 40 byte packets
  1  matrix.extremenetworks.com (192.167.201.40)  20.000 ms  20.000 ms  20.000 ms
  2  14.1.0.45 (14.1.0.45)  40.000 ms  10.000 ms  20.000 ms
  3  192.167.252.17 (192.167.252.17)  50.000 ms  0.000 ms  20.000 ms

Use the nslookup command, in any command mode, to query name servers, translating hostnames to IP addresses or IP addresses to hostnames.

System(su)->nslookup -x 127.0.0.1
Name: localhost
Address: 127.0.0.1
