I am getting some mixed information on how to best set up snmp traps on a VNX.  Should it be configured on the file side only?  Or should we be using the block template?  Right now, we have snmp configured on both the file and block sides of the array.  There are specific alerts that you can choose on the block template that i would like to ensure that i receive from the file side. 

If anyone has any tips for setting up snmp on the file side to ensure that the critical alerts send traps in meaningful way, please help.
