Add Delay Between PnP Deploy Image and Deploy Config

Working on a large deployment using APIC-EM PnP.

Have ISR4331s with 1MFT-T1/E1 & 2MFT-T1/E1 NIMs installed.

APIC-EM does not the normal deployment of the new image to each router, and then applies the configuration, however when I check the configuration after deployment, none of the serial interfaces are built.

I tried doing things manually and what I found is that if I wait an additional 90-120 seconds before deploying a configuration after performing the image upgrade that the serial interfaces do get provisioned correctly. I suspect the xMFT-T1/E1 cards themselves are performing some kind of upgrade and therefore are unavailable when the new configuration is applied immediately after deploying the new image.

So question is, is there a way to add a delay between deploying an image and deploying a configuration in APIC-EM PnP?

Hi Marc,

i usually embed this type of config in a small inline self-destructing EEM script.

here is one for "aaa",

Network Automation with Plug and Play (PnP) – Part 7

but you could do a simpler version for your serial config. Put something like this at the end of the configuration file that gets downloaded.

Strip out the serial config commands into this section
Change the timeout to 180sec or what ever is safe
debug event manager action cli is a useful command to run when testing to make sure the script is running properly.
This script will only run once, then remove itself. You need to do a "wr me" at the end to save the new config (including removing the EEM script)

event manager applet POST_PNP

! time in seconds

event timer countdown time 10

action 0.1 cli command "enable"

action 0.2 cli command "config t"

! what ever commands you want in here

action 1.0 cli command "int g3"

action 1.1 cli command "no shut"

action 2.0 syslog msg "PNP serial config by EEM "

action 3.0 cli command "no event manager applet POST_PNP"

action 3.1 cli command "end"

action 3.2 cli command "wr mem"

end
