4757.0. "How to perform multiple conditional SNMP sets & tests from a script?" by MDCRAB::STUART (Scott Stuart - MARVA Network Sales Support DTN 341-3132 - MARVA District) Wed Mar 24 1993 13:40

I am running DECmcc 1.3 under ULTRIX 4.3.

I would like some suggestions/examples of how to perform multiple SNMP sets
via DECmcc from a shell script/command procedure.  I know that I can do
a MCC> set SNMP x value y  

I can specify the command is a file and execute manage < file-spec

but I can think of a few problems with this...

Can I read the value of a variable between set operations within MCC?
In other words I want to test for true or false and then take a different
action depening on the value I get back.

Within the command line interface is there a test command? and is there a
conditional statement?

The problem I am trying to solve is to initiate dialbackup on a series of modems.
The variables I can tell me if the port is avaialable, to load a number, dial
a number, etc.  I need to test for the port being available 1st and then if yes,
load and dial that number.  I also need to test for success when I am done.

This needs to be repeated multiple times so that if I have to execute
manage each time, I am worried about performance.

Thanks for all suggestions... scott

You probably have a couple of options, both of which will be work. One of the options is to issue ALL your mcc commands to determine the availability of all the ports at once. If you use LOGGING all the info will be captured into a file which you could then read through and take either of the two appropriate actions. I agree, going in and out of mcc for each port will have performance problems so you could try this instead. The other option is to use alarms. If you can use some sort of wildcarding in the scheme this might be feasibile. If you have to maintain 1400 alarms for the job forget it. The alarm could be set up to fire regardless of the value passed which describes the port availability. This actual value is then passed into the alarm script. Check the value and execute dialbackup initiation if available or send mail (etc..) if not. best regards, brad...
