Generic SNMP traps do not contain a hostname as a variable.
You might be able to use the agent address, which would be an IP address, sent
as part of the trap. And as I just appended this morning, you can reference
that value in your slot mapping in trapd.conf as $AGENT_ADDR. I think you
should still be able to use the PRINTF function in the slot map to combine this
with another variable, but I have not tried that, so perhaps not.

Subject: Customizing Traps - Variable for Hostname on Generic SNMP Trap
Hi Netview Admins,
Environment : Tivoli Netview for Unix V5.1.1 (Solaris 2.6)
Tivoli Enterprise Console V3.6.1 (Solaris 2.6)
*NOTE* - Separate Servers
We pass Netview events using the internal adapter to TEC. Using the TEC
rulebase engine we send events to our trouble ticket system for 2nd level
support if certain conditions are met. The problem I am trying to solve is
with the generic SNMP traps (Link_Down/Link_UP) for our enterprise switches
In the case where I know a device such as a Server connected to the switch
will be down for maintenance, it is nice to have a "maintenance rule" in
place to ignore the events for the switch port. In order to place the
switch port under maintenance it is necessary to create a slot value that is
unique which will be used to identify the global variable in the Tivoli
rule. When we were using Netview V4.1.2 sending events with the external
adapter (tecad_nv6k) I was able to use the PRINTF function in the
tecad_snmp.cds file to create a new slot value which I called hostport. I
then appended hostname and interface_index to the slot which in all cases
created the unique port which I could use to put under maintenance.
Using the Event Configuration panels now to do the same work in v5.1.1, I
am having difficulty getting the append to work for the new slot value. For
the generic class Link Down the variable for the port index is nv_var1. I
can't seem to determine what the hostname variable is in the SNMP trap. For
the netmon events hostname is nv_var2, but this does not hold true for the
SNMP trap.
Any suggestions or ideas are appreciated.
Thanks,
