Test SNMPv1 Send Traps

Description

A ‘trap-target‘ is configured to send linkDown and linkUp traps for a community in DUT0 and the ‘monitor’ command is used to check sending notifications in SNMPv1.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces dummy dum0 address 20.0.0.1/24
set interfaces ethernet eth0 address 10.0.0.1/24
set service snmp community 'COMMUNITY2TEST!'
set service snmp trap-target 10.0.0.2 version v1 community 'COMMUNITY2TEST!'
set service snmp trap-target 10.0.0.2 version v1 source 10.0.0.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 10.0.0.2/24
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Note

First, no trap is received in DUT1, since DUT0 does not have any ‘notify-trap’ configured and therefore does not send them.

Step 3: Run command service snmp monitor traps community COMMUNITY2TEST! `` at ``DUT1.

Step 4: Modify the following configuration lines in DUT0 :

set interfaces dummy dum0 disable

Step 5: Run command service snmp monitor traps community COMMUNITY2TEST! `` at ``DUT1.

Step 6: Modify the following configuration lines in DUT0 :

delete interfaces dummy dum0 disable

Note

When configuring the sending of ‘link-down’ traps in DUT0, it must send traps when the ‘dum0’ interface is disabled. And these traps must be received in DUT1.

delete interfaces dummy dum0 disable

Note

When configuring the sending of ‘link-down’ and ‘link-up’ traps in DUT0, it must send traps when the ‘dum0’ interface is disabled and also when it is enabled. And these traps must be received in DUT1.

Step 12: Modify the following configuration lines in DUT0 :

set service snmp community 'COMMUNITY2TEST!' notify-traps link-up

set interfaces dummy dum0 disable

Step 20: Run command service snmp monitor traps community COMMUNITY2TEST! `` at ``DUT1.

Step 21: Modify the following configuration lines in DUT0 :

delete interfaces dummy dum0 disable

Note
