Please try the following for starters:

! Define a ReadOnly Community

snmp-server community RO

! Define an IP Interface, sourcing the traps. Make sure you verify ip connectivity to the NMS Server, from this interface.

snmp-server trap-source

! Define the NMS Server IP

snmp-server host

! Try this sample trap configuration
snmp-server enable traps snmp authentication linkdown linkup coldstart warmstart

You can define additional traps with the command:

snmp-server enable traps ?

Hope this helps.

Syslog can be configured by using the following

logging x.x.x.x

You can set the logging level of the traps that get sent ot the NMS using the:

logging trap [level] command.

Hope this helps,
