Catalyst Stacks - Priority

Claudia de Luna · ‎02-06-2017

Hi,

We are using the APIC-EM controller to stage quite a few 3850 and 3650 stacks.

Setting the switch priority is a command entered at the privileged EXEC prompt (vs in config mode) and these are routinely failing.

What is the recommended approach for these type of configuration commands? See config load log below.

Hi Claudia,

this looks like the switch member numbers are not correct?

If you do a "show switch" is there a member #1?

Yes, there is a switch 1. In this case we needed to pre-provition stacks.

config would look something like this:

vlan X

name xxxx

I understand now.

My usual trick to solve an "exec" command is to use a self-destructing EEM script.

I have a number of examples in blogs. There is a sophisticated example here Network Automation with Plug and Play (PnP) – Part 7

You could try something like:

event manager applet POST_PNP

event timer countdown time 30

action 1.0 cli command "enable"

action 1.1 cli command "switch 1 priority 15"

action 1.2 cli command "switch 2 priority 14"

action 2.3 cli command "no event manager applet POST_PNP"

action 2.8 cli command "end"

You put this just before the "end" in your PnP configuration file.

when i tested the above there was an issue:

The "switch 1 priority 15" command is an interactive command, and prompts you for a "y/n" response.

I also did another "wr me" to get rid of the EEM script from the startup configuration file as well as the running config.

A working version of the EEM script is:

event manager applet POST_PNP

event timer countdown time 30

action 1.0 cli command "enable"

action 1.1 cli command "switch 1 priority 15" pattern "continue"

action 1.2 cli command "y"

action 1.8 cli command "config t"

action 2.3 cli command "no event manager applet POST_PNP"

action 2.8 cli command "end"

action 2.9 cli command "wr mem"

action 3.0 cli command "end"
