configuring Cisco 3745 to send snmp traps

how do i configure my cisco 3745 (Version 12.3(26)) to send snmp and syslog traps to my nms.

I have tried the following commands with no success:

snmp-server host x.x.x.x traps version 1 public snmp-server enable traps config snmp-server enable traps snmp linkdown linkup coldstart snmp-server enable traps syslog logging history 4

also received this error msg in router logs:

CRYPTO-6-IKMP_MODE_FAILURE: Processing of Quick mode failed with peer at x.x.x.x

thanks.
