cmnMacChangedNotification trap not triggering traphandle

Hi All,

I am new to NetSNMP, and am trying to get a solid snmptrapd.conf put up.  Most things seem to be working as designed, but I noticed that I am not processing Mac traps (1.3.6.1.4.1.9.9.215.2.01 - 3).  I have a catchall in snmptrapd.conf that should log anything that falls through if I have the wrong OID, which does not catch the trap if I comment out the relevant traphandle section.  Below is a summary of my snmptrapd.conf:

doNotFork false

logOption f /netmgt/log/snmptrapd.log

outputOption SEX

format1 v1 Trap from %B

format2 v2 Trap from %B

disableAuthorization yes

traphandle 1.3.6.1.4.1.9.9.215.2.0.1 /netmgt/bin/trap_default.pl mac cmnMacChangedNotification 4 2
traphandle 1.3.6.1.4.1.9.9.215.2.0.2 /netmgt/bin/trap_default.pl mac cmnMacMoveNotification 4 2
traphandle 1.3.6.1.4.1.9.9.215.2.0.3 /netmgt/bin/trap_default.pl mac cmnMacThresholdExceedNotif 4 2

traphandle default /netmgt/bin/trap_default.pl "undefined trap" UNDEFINED 0 0 


I see the traps coming in droves on the server when I do a tcpdump:

tcpdump:
21:22:34.561674 IP (tos 0x0, ttl 252, id 54940, offset 0, flags [none], proto: UDP (17), length: 137) switch.XXX.edu.57704 > trapdev.XXX.edu.snmptrap:  { SNMPv1 C=Trap { Trap(91)  E:cisco.9.215.2 10.1.1.11 enterpriseSpecific s=1 3626105156 [|snmp] } } 
21:23:48.045910 IP (tos 0x0, ttl 252, id 54941, offset 0, flags [none], proto: UDP (17), length: 137) switch.XXX.edu.57704 > trapdev.XXX.edu.snmptrap:  { SNMPv1 C=Trap { Trap(91)  E:cisco.9.215.2 10.1.1.11 enterpriseSpecific s=1 3626112504 [|snmp] } } 


iptables is wide open:

iptables -L -n | grep 162
ACCEPT     tcp  --  10.0.0.0/8           0.0.0.0/0           tcp dpt:162 
ACCEPT     udp  --  10.0.0.0/8           0.0.0.0/0           udp dpt:162


I enabled debug options:

/etc/sysconfig/snmptrapd.options:
OPTIONS="-C -c "/netmgt/etc/snmptrapd.conf" -Leof -F \"element_name=%A;;event_name=%W;;varbinds=%#v;;trap=(%N)(%q)(%w);;\n\" -OSEX -D all"


Every looks OK to my untrained eye:

snmptrapd.log:
trace: read_config(): read_config.c, 795:
read_config: /netmgt/etc/snmptrapd.conf:132 examining: traphandle 1.3.6.1.4.1.9.9.215.2.0.1 /netmgt/bin/trap_default.pl mac cmnMacChangedNotification 4 2
trace: run_config_handler(): read_config.c, 498:

However, I still do not see the traps being logged from the traphandle script or in my log dir.  What else can I do to troubleshoot?  Am I missing something basic?  Version info below:

snmptrapd -v

Thank you in advance,
