Procedure 6-4 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:

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. Table 6-2 lists the default ports and their values.
Note — Track any changes to port configuration values for future
reference.
