Can I track 2 events in one EEM Applet

[Richard Bradfield]

I want to create an EEM script that changes some BGP network parameters when a remote site goes down, so Have an SLA to the public address of remote site. see below

track 1 ip sla 1 reachability

delay down 8 up 10

ip sla 1

icmp-echo 1<remote site public address

 timeout 4000

threshold 3000

frequency 30

ip sla schedule 1 life forever start-time now

track 2 ip sla 2 reachability

delay down 8 up 10

ip sla 2

icmp-echo 8.8.8.8 <Google public dns

 timeout 4000

threshold 3000

frequency 30

ip sla schedule 2 life forever start-time now

event manager applet Head-office-down

event track 1 state down

action 1.0 cli command "enable"

action 1.1 cli command “config t”

action 1.2 cli command “router bgp 64599”

action 1.3 cli command “address-family ipv4”

action 1.4 cli command “ network 121.200.231.128 mask 255.255.255.240”

action 1.5 cli command “network 150.207.153.224 mask 255.255.255.240”

action 1.6 cli command "int fa0/1"

action 1.7 cli command "no shut"

would work for remote site, but I also need to check that this site can still get to the Internet. Obviously I dont want this change to happen if the Internet is down locally at this site.

 Is there a simple fix for this?

regards

Richard

One option is to look for the state of track 2 inside of the EEM policy.  If track 1 goes down, and track 2 remains up, then make the change, otherwise no changes made.

event manager applet Head-office-down

event track 1 state down
trigger delay 30
action 010 cli command "enable"
action 020 cli command "show track 2 | inc Reachability"
action 030 regexp "Reachability is Up" "$_cli_result"
action 040 if _regexp_result eq "1"
action 050 cli command "conf t"
action 060 cli command "router bgp 64599"
action 065 cli command "address-family ipv4"
action 070 cli command "network 121.200.231.128 mask 255.255.255.240"
action 080 cli command "network 150.207.153.224 mask 255.255.255.240"
action 090 cli command "int fa0/1"
action 100 cli command "no shut"
action 110 end

Daniel,

Only just got to try this script! does not work Event manager version is 3.20

I changed action 020 to cli command "show track 2 | inc Reachability is" because when you show track there is 2 lines with Reachability, so Thought it would narrow it down to just one line.

note the line action 040 if _regexp_result eq "1"  when I look at it in the config is

action 040 if _regexp_result eq 1 no inverted commas around the 1

here is the debug event manager action cli

Jun  8 21:45:28 AEST: %TRACKING-5-STATE: 1 ip sla 1 reachability Up->Down
Jun  8 21:45:33 AEST: %HA_EM-6-LOG: DMT-Internet-down : DEBUG(cli_lib) : : CTL : cli_open called.

Jun  8 21:45:33 AEST: tty is now going through its death sequence

Hope you can help

should line  040 be if $ _regexp_result eq 1

[Joe Clarke]

Yes.  Well:

action 040 if $_regexp_result eq 1

Hi Daniel,

thanks for the response, I knew there must be a way of doing it.

I am just getting old and lazy!

thanks again

Richard
