Sun Microsystems MEDIACENTER 2.1 - Manual (Page 146)

A-2 Sun MediaCenter Server Administrator’s Guide • December 1997
Note – A caveat on the use of the SNMP agent shipped with the Sun MediaCenter
server: If you use SNMP to manage the Sun MediaCenter software, you cannot also
run an SNMP agent to manage other components of your system (for example, the
ATM interface). The SNMP agent reserves port 161, making that port unavailable to
other SNMP agents.
The SNMP agent is implemented in a daemon, snmpd , and is installed on the Sun
MediaCenter server in the course of running pkgadd to add the SUNWsmsnm
package. The package-install script adds a snmpd startup script to /etc/init.d .
Beyond running pkgadd , no action is required on your part to install or start snmpd .
A.1 The Sun MediaCenter Server MIB
The Sun MediaCenter Server Management Information Base (MIB) is defined in the
file
sms_vod.mib , stored by default in /opt/SUNWsms/agents . A MIB contains
attributes that collectively describe a network object. sms_vod.mib describes a Sun
MediaCenter server. MIB attributes are readable—and in some cases settable—by a
program that conforms to the Simple Network Management Protocol (SNMP). All
of the attributes in
sms_vod.mib are read-only, meaning you cannot use SNMP to
change their values.
MIB attributes are categorized by groups and tables. TABLE A-1 lists the groups and
tables in sms_vod.mib .
