Procedure 7-3 Problem: Another machine can be pinged, but some

functions are unavailable

Check the following to determine whether port availability or routing is the cause of
management domain LAN issues:
1
Alcatel-Lucent 5620 Service Aware Manager, Release 6.1 R3
3HE 04244 AAAB Ed. 01
b For workstations:
ping -s name_of_machine ↵
where name_of_machine is the name of the network management domain workstation
Review the output. The following shows sample output.
# ping -s name_of_machine
PING name_of_machine: 56 data bytes
64 bytes from name_of_machine (138.120.106.169): icmp_seq=0,
time=1. ms
64 bytes from name_of_machine (138.120.106.169): icmp_seq=1,
time=0. ms
64 bytes from name_of_machine (138.120.106.169): icmp_seq=2,
time=0. ms
^C
----name_of_machine PING Statistics----
3 packets transmitted, 3 packets received, 0% packet loss
round-trip (ms) min/avg/max = 0/0/1
If the packets were received out of order, if some packets were dropped, or if
some packets took too long to complete the round trip, LAN congestion may be a
problem. Contact your IT department or check physical LAN connectivity
according to your company policy.
ports that need to be open across firewalls
•
routing using netstat and ARP
•
The 5620 SAM uses numerous TCP and UDP ports for communication between
various services. Some of these ports, such as the SNMP trap port, are configured
during installation. Other ports are configured automatically by the software.
Check that these ports are open or protected by a firewall, depending on system
architecture needs.
The complete list of ports, their use, and the default port numbers are listed in
the firewall section of the 5620 SAM Planning Guide.
