有防火墙的情况下，得把udp 161 端口打开了

\[root@zhudoubaby ~\]\# iptables -L  
Chain INPUT (policy ACCEPT)  
target     prot opt source               destination           
RH-Firewall-1-INPUT  all  --  anywhere             anywhere              
  
Chain FORWARD (policy ACCEPT)  
target     prot opt source               destination           
RH-Firewall-1-INPUT  all  --  anywhere             anywhere              
  
Chain OUTPUT (policy ACCEPT)  
target     prot opt source               destination           
  
Chain RH-Firewall-1-INPUT (2 references)  
target     prot opt source               destination           
   
ACCEPT     udp  --  anywhere             anywhere            state NEW udp dpt:snmp    （必须的）
