Start of snmp trap self-TRAP

Snmp trap is as famous as SNMP proxy. TRAP is also a very important part of SNMP protocol applications. So let's take a look at this part. We know that TRAP is the self-trapping feature of SNMP. How can we RUN this feature in the system?

Cisco snmp Configuration

In the Enable status of IOS, enter config terminal to enter the global configuration status.

Enable Cdp run

Snmp-server community gsunion ro: configure the read-only string of this vro as gsunion

Snmp-server community gsunion rw: configure the read/write string of the vro as gsunion.

Snmp-server enable traps allow routers to send all types of SNMP traps

Snmp-server host IP-address-server traps trapcomm specifies that the receiver of the SNMP Trap on the router is 10.238.18.17. trapcomm is used as the string to send the Trap.

Snmp-server trap-source loopback0 uses the IP address of the loopback interface as the sending source Address of the SNMP Trap.
