EEM KONFIGURASI EVENT SYSLOG - NETWORK AUTOMATION #8 ( CCNP )

 NETWORK AUTOMATION #8 :

EEM KONFIGURASI EVENT SYSLOG 

Embedded Event Manager (EEM) ini adalah sebuah teknologi cisco yang
memungkinkan perangkat untuk menjalankan script atau perintah secara
otomatis ketika ada event (kejadian) tertentu

Konfigurasikan IP Address dan routing OSPF pada kedua router

 
R1
R1(config)# interface f0/0
R1(config-if)# ip address 12.12.12.1 255.255.255.0
R1(config-if)# no shutdown
R1(config-if)# exit
!
R1(config)# interface loopback0
R1(config-if)# ip address 1.1.1.1
255.255.255.255
R1(config-if)# exit
!
R1(config)# router ospf 10
R1(config-router)# network 1.1.1.1 0.0.0.0 area 0
R1(config-router)# network 12.12.12.0 0.0.0.255 area 0
R1(config-router)# exit
R2
R2(config)# interface f0/0
R2(config-if)# ip address 12.12.12.2 255.255.255.0
R2(config-if)# no shutdown
R2(config-if)# exit
!
R2(config)# interface loopback0
R2(config-if)# ip address 2.2.2.2 255.255.255.255
R2(config-if)# exit
!
R2(config)# router ospf 10
R2(config-router)# network 2.2.2.2 0.0.0.0 area 0
R2(config-router)# network 12.12.12.0 0.0.0.255 area 0
R2(config-router)# exit

Coba buat custom syslog dengan EEM

 
R1
R1(config)#event manager applet INTERFACE_DOWN
R1(config-applet)#event syslog pattern "Interface FastEthernet0/0, changed
state to down"
R1(config-applet)#action 1.0 cli command "enable"
R1(config-applet)#action 2.0 cli command "conf term"
R1(config-applet)#action 3.0 cli command "interface
fa0/0"
R1(config-applet)#action 4.0 cli command "no shut"

Script diatas berarti kalo ada log dengan tulisan seperti ini “Interface
FastEthernet0/0, changed state to down" maka tolong tulis enable dan no
shutdown interfacenya. Dan coba lakukan debug untuk melihat prosesnya.

Lalu shutdown interface f0/0
R1
R1#debug event manager action cli Debug EEM action cli debugging is on
R1(config)#interface f0/0
R1(config-if)#shutdown
R1(config-if)#exit
R1
R1(config)#

Jika kita perhatikan perangkat kita langsung menjalankan script untuk
menghidupkan kembali interface f0/0.
