Default Problem with linkUpDownNotifications

Hi everyone,

I am using Net-snmp on Fedora core 4. I could not enable the it to send trap whenever the ethernet link up/down.
- Net-SNMP version: 5.3.0.1, configure with disman module
- Part of my snmpd.conf looks like:
################################################## #############################
#DisMan EventMIB
# Set up the credentials to retrieve monitored values
agentSecName internal
rouser internal
# Active the standard monitoring entries
defaultMonitors yes
linkUpDownNotifications yes
- When I run snmpd, I only got
17:54:51 ------
IP: 192.168.1.100
Uptime: DISMAN-EVENT-MIB::sysUpTimeInstance 0:0:00:00.19
Trap OID: DISMAN-EVENT-MIB::mteTriggerFired
Not Matched: DISMAN-EVENT-MIB::mteHotTrigger.0 process table
Not Matched: DISMAN-EVENT-MIB::mteHotTargetName.0
Not Matched: DISMAN-EVENT-MIB::mteHotContextName.0
Not Matched: UCD-SNMP-MIB::prErrMessage.1 No mountd process running.
Line 1 is: DISMAN-EVENT-MIB::mteHotOID.0 ==> UCD-SNMP-MIB::prErrorFlag.1
Line 2 is: DISMAN-EVENT-MIB::mteHotValue.0 ==> 1
Line 3 is: UCD-SNMP-MIB::prNames.1 ==> mountd
New Trap ID: 50
17:54:53 ------
IP: 192.168.1.100
Uptime: DISMAN-EVENT-MIB::sysUpTimeInstance 0:0:00:00.21
Trap OID: SNMPv2-MIB::coldStart
Line 1 is: SNMPv2-MIB::snmpTrapEnterprise.0 ==> NET-SNMP-MIB::netSnmpAgentOIDs.10
New Trap ID: 51

Also, when i do snmpwalk -v 1 -c TEST localhost .1.3.6.1.2.1.31.1.1.1 ,it returns
IF-MIB::ifLinkUpDownTrapEnable.1 = INTEGER: 0
IF-MIB::ifLinkUpDownTrapEnable.2 = INTEGER: 0
IF-MIB::ifLinkUpDownTrapEnable.3 = INTEGER: 0
IF-MIB::ifLinkUpDownTrapEnable.4 = INTEGER: 0
That means it hasn't enabled the LinkUpDownTrap, right? Can anyone give me some advice?
What does the agentSecName internal & rouser internal means in this case?
Thanks for your help.
