How do I check network management connections?

Steps
 
1 

Open a console window on the station.

2 

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

3 

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.

4 

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.

5 

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.

6 

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

7 

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

8 

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