Hi Stipa_IT,

When you do "show snmp-server" do you see the community strings listed with which traps are enabled, something like this???

Switch01# sh snmp-

SNMP Communities

Community Name MIB View Write Access
-------------------------------- -------- ------------
public Operator restricted
private Manager Unrestricted

Link-Change Traps Enabled on Ports [All] : All

if not you might need to enable snmp on the switch "snmp-server enable". otherwise you should be good to go.

HTH.

SW3_STIPA(config)# snmp-server enable

I had similar issues.

You’re requests arrives on VLAN 12, and the Procurve reply’s with the address of VLAN 12 (192.168.12.13) which is not the address you requested.

SNMP to ip 192.168.12.13, or add the following to your config:

snmp-server response-source 10.0.0.3
