write mem via SNMP?

[yjdabear]

Is there any way to perform a "write mem" or "copy run start" via SNMP (snmpget) on IOS, CatOS or PIX/ASA?

Sure! Use the CISCO-CONFIG-COPY-MIB to do this:

https://www.cisco.com/en/US/tech/tk648/tk362/technologies_configuration_example09186a0080094aa6.shtml

That tech tip details copying the config to and from a TFTP server, but for a write mem, set the destination as startup and the source as running, and you're set.

Oh, this is not possible on the PIX/ASA as config manipulation is not possible using SNMP.

Thanks! I thought it wasn't possible, but I should've searched:

In the above thread, Nadim gave an example in which ccCopyEntryRowStatus was set to "5:createAndWait", whereas in the URL you pointed out "createAndGo(4) : Create an entry" and "destroy(6) : Delete an entry" were suggested. Would you know what the differences are between 4 (createAndGo) and 5 (createAndWait), specifically which one would you choose to commit a "write mem"?

Secondly, how is the random number below generated? Is that my choice?

snmpset -v 1 -c private

.1.3.6.1.4.1.9.9.96.1.1.1.1.2. integer 1

.1.3.6.1.4.1.9.9.96.1.1.1.1.3. integer 4

.1.3.6.1.4.1.9.9.96.1.1.1.1.4. integer 1

.1.3.6.1.4.1.9.9.96.1.1.1.1.5. ipaddress ""

.1.3.6.1.4.1.9.9.96.1.1.1.1.6. octetstring ""

.1.3.6.1.4.1.9.9.96.1.1.1.1.14. integer 4

createAndWait lets you perform the set in multiple packets. When using createAndGo, you have to send all the objects in the same packet. You can do either one.

The random number is your choice. It can be anything in the range of 1 to 2^31-1.
