I have the switch set up for mac notification, and the switch has the below config. But no mac notification traps get sent to the CAM.
interface GigabitEthernet1/0/24
switchport access vlan 800
switchport mode access
snmp trap mac-notification added
spanning-tree portfast

Below is a debug of snmp packets when a host it connected to the switch on port 1/0/24

Am I missing something in the config or something?

Hello,
Please post your SNMP receiver config on the CAM. Also, can you do a capture on the CAM to see if you're seeing the packets getting there?
To do the capture, in a SSH session, use this command: tcpdump -ieth0 'host
Once you've captured the success/failure, hit Ctrl-C to kill the capture. You can then use WINSCP or any other SCP program to get that file off of the CAM for further analysis.
HTH,
Faisal

fixed it the guy who configured the switches swapped the read and write strings, and I caught that when adding the switch but he also swapped the v1 and v2 strings. its working now.
