Issue with EEM snmp-object event GET on table

sbertsch
Beginner
Beginner

I'm trying to use SNMP GET interception with 'istable yes'.    Ideally, I would like to pass the entire OID to a Tcl script that will then use the table index as an input to alter its behavior in generating the output, which will then be passed as a variable to the snmp-object-value action.

Here's the sample config used with my test:

event manager applet getTest

event snmp-object oid 1.9.9.9.9 type int sync yes istable yes

action 10 syslog msg "OID: $_snmp_oid"

action 20 snmp-object-value event-id _event_id int 1234 next-oid 1.9.9.9.10

action 30 exit 1

!

Here's the response, including the value of _snmp_oid:

R2(tcl)#snmp_getone private 1.9.9.9.9.3.2.1

{<obj oid='iso.9.9.9.9' val='1234'/>}
