event manager applet test_down
event syslog pattern “%TRACK-6-STATE: 3 list boolean and Up -> Down”
action 1 cli command “enable”
action 2 cli command “configure terminal”
action 3 cli command “interface range Et0\/2-3”
action 4 cli command “shutdown”
action 5 cli command “end”
action 8 cli command “write memory”<\/p>\n\n\n\n

<\/p>\n\n\n\n

Track up we use here Track 4 – if any one of the up we bring up the interface range<\/p>\n\n\n\n

event manager applet test_up
event syslog pattern “%TRACK-6-STATE: 4 list boolean or Down -> Up”
action 1 cli command “enable”
action 2 cli command “configure terminal”
action 3 cli command “interface range Et0\/2-3”
action 4 cli command “no shutdown”
action 5 cli command “end”
action 8 cli command “write memory”<\/p>\n\n\n\n

Testing shutdown eth0\/0 and eth0\/1<\/p>\n\n\n\n

%TRACK-6-STATE: 1 ip sla 1 reachability Up -> Down<\/p>\n\n\n\n

%TRACK-6-STATE: 2 ip sla 2 reachability Up -> Down<\/p>\n\n\n\n

%TRACK-6-STATE: 3 list boolean and Up -> Down<\/p>\n\n\n\n

and EEM Script runs :<\/p>\n\n\n\n

%SYS-5-CONFIG_I: Configured from console by on vty0 (EEM:test_down)<\/p>\n\n\n\n

we can see eth0\/2 and0\/3 disabled – that means EEM script run as expected<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Lets bring up Eth 0\/0 and eth 0\/1 and show track 3<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

and we can see log message EEM Script up activated.<\/p>\n\n\n\n
