The default UDP port number that the managed entity is
using to send syslog messages.
This value will be used as the default value for
etsysSyslogServerUdpPort when creating rows in the
etsysSyslogServerTable and either:
1.) no value is specified for etsysSyslogServerUdpPort, or
2.) etsysSyslogServerUdpPort is implemented read-only.
If etsysSyslogServerUdpPort is implemented read-only,
and this value is changed, it should affect the UDP
port that is used to send syslog messages to all
servers as soon as it is practical.
This parameter value is maintained across system reboots.
