Problem: Lost connectivity to one or more network management domain stations
Purpose
Perform this procedure on a RHEL or Windows station to check the reachability of another station.
Steps
1 |
Log in to the station. |
2 |
Open a console window. |
3 |
Enter the following: ping station ↵ where station is the station hostname or IP address |
4 |
To interrupt the ping operation, press Ctrl+C. |
5 |
Review the output, which resembles the following when connectivity is good: PING station: 56 data bytes64 bytes from station (192.168.106.169): icmp_seq=1, time=1.0 ms64 bytes from station (192.168.106.169): icmp_seq=2, time=0.3 ms64 bytes from station (192.168.106.169): icmp_seq=3, time=0.2 ms----station PING Statistics----3 packets transmitted, 3 packets received, 0% packet lossrtt (ms) min/avg/max = 0.2/0.7/1.0 |

If the packets arrive out of order, if some packets are dropped, or if some packets take too long to complete the round trip, LAN congestion may be a problem. Contact your IT department or check the physical LAN connectivity. |

If you can ping the station, but are unable to connect to the station to perform a function, there may be a problem with access to a function on the station. If the NFM-P deployment includes a firewall, the firewall log entries are in the /var/log/messages file on a RHEL station. See Purpose for information about how to verify the following: End of steps |
