[j-nsp] Help: SNMP Trap problem

[Yuki Arif (JA/EID)]

Hello All,
 
I have M20. When my M20 (172.21.11.1) sends trap message to SNMP server, I get like this 
 
13:24:41.578440 Out IP 172.21.11.1.3235 > 10.21.120.131.snmptrap: Trap(35) E:2636.1.1.1.2.2 172.21.11.1 linkDown 949639883 [|snmp]

Can you give me some lights why machines 10.21.120.132 and 131 are replying back like above ?.

172.21.4.10 Machine accepts the traps.

 

 

Best Regards

 

Yuki
