: %HA_EM-3-FMPD_CLI_CONNECT: Unable to establish CLI session: 'Embedded Event Manager' detected the 'fatal' condition 'error from operating system'

Hi,

I am testing new Cisco ISR4331/K9 (1RU) for the DMVPN with Fail over solution. Here are some guild lines:

Router: ISR4331/K9

IOS: Cisco IOS XE Software, Version 03.15.01c.S - Standard Support Release
Cisco IOS Software, ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.5(2)S1c, RELEASE SOFTWARE (fc1)

"bootflash:/isr4300-universalk9.03.15.01c.S.155-2.S1c-std.SPA.bi"

Scenario: I have setup two cradle points acting as PRIMARY and SECONDARY WAN circuits. Its establishing DMVPN tunnel with 4 Hubs but as soon as I shutdown the PRIMARY link its doesn't fail over to SECONDARY one until I manually clearing the NAT Translation. I have EEM Event template configured to run those commands but its failing to execute the commands.

Here is the EEM:

event manager applet ISP1-up
 event syslog pattern "ip sla 1 reachability Down -> Up"
 action 1 cli command "enable"
 action 2 cli command "clear crypto sa"
 action 3 cli command "config ter"
 action 4 cli command "inter tun 0"
 action 5 cli command "shut"
 action 6 cli command "clear ip nat trans *"
 action 7 cli command "no shut"

event manager applet ISP1-down
 event syslog pattern "ip sla 1 reachability UP -> Down"
 action 1 cli command "enable"
 action 2 cli command "clear crypto sa"
 action 3 cli command "config ter"
 action 4 cli command "interface tun 0"
 action 5 cli command "shut"
 action 6 cli command "clear ip nat trans *"
 action 7 cli command "no shut"

When I debug and see the following error: :

007580: Jan 25 15:38:36.283 EST: %HA_EM-3-FMPD_CLI_CONNECT: Unable to establish CLI session: 'Embedded Event Manager' detected the 'fatal' condition 'error from operating system'

007581: Jan 25 15:38:36.283 EST: %HA_EM-3-FMPD_ERROR: Error executing applet ISP1-up statement 1

I removed the NO EXEC from VTY line but no luck!!!

Anyone experiencing similarity situation? please share your ideas!

You ever find a solution?

I have the exact same error messages. Need to to do a no shut on a cellular interface if a Boolean track goes down.
