Since the Nortel official documents never mention a full statement for VRRP trap messages, I would like to post these massages and translations here.

This is an example of VRRP state transition trap:

CPU5 [07/07/08 03:40:49] SNMP INFO Vrrp State Transition Trap(Port/Vlan=100, Type=6, Cause=14, VrId=100, VrIpAddr=10.100.12.1, Addr=10.100.12.3)
CPU5 [07/07/08 03:40:50] SNMP INFO Vrrp State Transition Trap(Port/Vlan=100, Type=3, Cause=13, VrId=100, VrIpAddr=10.100.12.1, Addr=10.100.12.3)

Those parts of logs are easy to be identified except the Type and Cause code.

Listed below are the codes for the Types and Causes of the transition and I hope this can help your troubleshooting.

Transition Type:

1 - None
2 - Master to Backup
3 - Backup to Master
4 - Initialize to Master
5 - Master to initialize
6 - Initialize to Backup
7 - Backup to Initialize
8 - Backup to Backup Master
9 - Backup Master to Backup

Transition Cause:

1 - None
2 - Higher priority advertisement received
3 - Shutdown received
4 - VRRP Address and Physical Address match
5 - Master Down interval
6 - Preemption
7 - Critical IP goes down
8 - User Disabling VRRP
9 - VRRP status synced from primary
10 - IP interface on which VRRP is configured goes down.
11 - Lower Priority Advertisement received
12 - Advertisement received from Higher interface IP address with Equal priority
13 - Advertisement received from Lower interface IP address with Equal priority
14 - User enabled VRRP 15 - Transition because of any other cause
