Use the show snmp-server command to display the current SNMP configuration:

Pix(config)# show snmp-server
snmp-server host inside 192.168.1.3
snmp-server host dmz 192.168.2.3
snmp-server location Building 19-67B
snmp-server contact Network Security
snmp-server community MySNMP
snmp-server enable traps
Pix(config)# 

The clear snmp-server command clears most of the SNMP entries. It restores the community key “public” and leaves the snmp-server enable traps command.
