Serviceguard Manager has the following port requirements:
• The Serviceguard node must allow the following communications:

— udp on port 161

— udp on port 162
• The Serviceguard Manager node must allow the following
communications:

NOTE If you suspect that the firewall is blocking communications, you can add

/etc/sysconfig/iptables) to log any blocked ports. Consult your
Linux distribution’s documentation on firewalls for information on
iptables.
