Hi,
snmp-server community Windows2009 RO - This is the SNMP community string, probably not a good idea to post this in a public forum!!
snmp-server enable traps tty
snmp-server enable traps cpu threshold
snmp-server enable traps config
snmp-server enable traps bridge newroot topologychange
snmp-server enable traps syslog
You can see what the different traps notify on here;

I'm not sure if there's a recommended set of traps you can configure, it really depends on your network and what level of visibility you need on your devices.
Personally, at a minimum I would want to know if the switch reboots (cold or warm reload) and if the cpu or memory are over utilised. I also want to know if the configuration has changed so I can audit this against our change management process.

Hi Wajid,
As you know, we have 2 community strings, public and private (by default) which is used for setting Read-Only (RO) and Read-write(RW).
Here in our case, we have configured the 1st line as RO type having the string value as 'Windows2009'.
tty - Sends Cisco enterprise-specific notifications when a TCP connection closes
cpu threshold - Enables CPU thresholding violation notification as traps and inform requests
config - This will be triggered when there is a router configuration changes.
bridge newroot topologychange - Generate STP bridge MIB traps.
It has the below keywords and its meaning:
newroot—(Optional) Enable SNMP STP Bridge MIB new root traps.
topologychange—(Optional) Enable SNMP STP Bridge MIB topology change traps.
syslog - enables the router to send system logging messages
The below are few of the references which may help you in taking a decision before you apply on a network.
