How do I check network management connections?

Steps
 

Open a console window on the station.


Ping the hostname of another station in the network management domain by entering the following:

ping station_name

where station_name is the IP address or hostname of the other station


Review the output. The following is an example of ping output:

PING station_name: 56 data bytes

64 bytes from hostname (IP_address): icmp_seq=0, time=nnn ms

64 bytes from hostname (IP_address): icmp_seq=1, time=nnn ms

64 bytes from hostname (IP_address): icmp_seq=2, time=nnn ms

----station_name PING Statistics----

3 packets transmitted, 3 packets received, 0% packet loss

round-trip (ms) min/avg/max = 0/0/1

LAN congestion may be a problem if packets are received out of order, are dropped, or take too long to complete the round trip.


Store the output for future base measure comparison.

Compare the output over time to ensure that changes in the data are not caused by deteriorating LAN conditions.


Check the routing information.

  1. Open a console window on the station.

  2. Enter one of the following traceroute commands to determine the path taken to a destination by an ICMP echo request message:

    • traceroute ↵ on a RHEL station

    • tracert ↵ on a Windows station

    The list of near-side interfaces in the path between a source host and a destination device is displayed. The near-side interfaces are the interfaces closest to the source host.


Store the output as a record for future base measure comparisons. Compare routes over time to ensure that there is optimal connectivity.


To check the routing tables for the platform:

  1. Open a console window on the station.

  2. To view the active routes for the platform, type:

    netstat -rn ↵

    The following information is displayed:

    • network destination and gateway IP addresses

    • gateway used to reach the network destination

    • IP address of the interface on which communication occurs

    • metric value of the route


Store the output as a record for future base measure comparison. Compare routes over time to ensure that there is optimal connectivity.
