Firewall Configuration on Systems Running Supported Red Hat Enterprise Linux Operating Systems
If you enable firewall security when installing Red Hat Enterprise Linux, the SNMP port on all external network interfaces is closed by default. To enable SNMP

interfacemustbeopen.IfServerAdministratordetectsthattheSNMPportisnotopeninthefirewallforanyexternalnetworkinterface,ServerAdministrator
displays a warning message and logs a message to the system log. See "Ports"foradditionalinformation.
You can open the SNMP port by disabling the firewall, opening an entire external network interface in the firewall, or opening the SNMP port for at least one
external network interface in the firewall. You can perform this action before or after Server Administrator is started.
