Konfigurasi Event Syslog

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.
