Symptoms

By default when SNMP alert channel is created from WebUI it would use snmpinform to send SNMP notification:
  
# isi event channels list -v
--------------------------------------------------------------------------------
            ID: 5
          Name: snmp-test
          Type: snmp
       Enabled: Yes
 Allowed Nodes: -
Excluded Nodes: -
       Address: -
       Send As: -
       Subject: -
     SMTP Host: -
     SMTP Port: -
 SMTP Use Auth: -
 SMTP Username: -
 SMTP Password: -
 SMTP Security: -
         Batch: -
  Batch Period: -
          Host: 1.1.1.1
     Community: test
 Use Snmp Trap: -         <============= indicate use of snmpinform instead of snmptrap

The behavior can be changed to instead use snmptrap via command:
  
# isi event channels modify <snmp channel name> --use-snmp-trap true

In this example: 
# isi event channels modify snmp-test --use-snmp-trap true
  
# isi event channels list -v
--------------------------------------------------------------------------------
            ID: 5
          Name: snmp-test
          Type: snmp
       Enabled: Yes
 Allowed Nodes: -
Excluded Nodes: -
       Address: -
       Send As: -
       Subject: -
     SMTP Host: -
     SMTP Port: -
 SMTP Use Auth: -
 SMTP Username: -
 SMTP Password: -
 SMTP Security: -
         Batch: -
  Batch Period: -
          Host: 1.1.1.1
     Community: test
 Use Snmp Trap: Yes       <============ now using snmptrap
However, if you make any modification to the SNMP alert channel via WebUI, it would reset the flag and revert back to use snmpinform:

* change community from test to test2 via WebUI
  
# isi event channels list -v
--------------------------------------------------------------------------------
            ID: 5
          Name: snmp-test
          Type: snmp
       Enabled: Yes
 Allowed Nodes: -
Excluded Nodes: -
       Address: -
       Send As: -
       Subject: -
     SMTP Host: -
     SMTP Port: -
 SMTP Use Auth: -
 SMTP Username: -
 SMTP Password: -
 SMTP Security: -
         Batch: -
  Batch Period: -
          Host: 1.1.1.1
     Community: test2
 Use Snmp Trap: -         <============= the channel reverts back to use snmpinform

Cause

WebUI does not properly set parameter use_snmp_trap based on the channel's existing configuration, so any update to the channel would reset the channel back to its default configuration.

Resolution

WORKAROUND:

If you use WebUI and make change to any SNMP alert channel, you need to manually set the flag for using snmptrap if it was configured to use snmptrap before change via WebUI.  To do so use command:
  
# isi event channels modify <snmp channel name> --use-snmp-trap true
and verify Use Snmp Trap is set to Yes.  For example:
  
# isi event channels list -v
--------------------------------------------------------------------------------

          Name: snmp-test
          Type: snmp
