Konfigurasi Event OSPF Adjacency (Email)

Konfigurasi Event OSPF Adjacency (Email) LAB INI LANJUTAN SAMA SEPERTI LAB SEBELUM SEBELUMNYA Selain event syslog tadi kita juga bisa memanfaatkan EEM ini untuk mengirimkan informasi ke email kita, misalnya OSPF kita down maka, router kita otomatis akan mengirimkan debug ospf ke email kita. Untuk topology masih sama. KONFIG R1 R1(config)#event manager applet OSPF_DOWN R1(config-applet)#event syslog pattern "Nbr 2.2.2.2 on FastEthernet0/0 from FULL to DOWN" R1(config-applet)#action 1.0 cli command "enable" R1(config-applet)#action 2.0 cli command "debug ip ospf adj" R1(config-applet)#action 3.0 mail server "smtp.gmail.com" to "uuqeili@gmail.com" from "R1@idn.id" subject "OSPF IS DOWN" body "Please fix OSPF" R1(config-applet)#exit Untuk Pengecekkan, kita bisa coba debug aja, dan hapus EEM interface down, Dan kita bisa lihat di email kita apa hasilnyaa... selesai

Remote SPAN ( RSPAN )

Remote SPAN ( RSPAN ) Assalamualaikum temen - temen... kembali lagi di blogg saya, dan terimakasih telah berkunjung ke blogg saya, di blogg kali ini saya akan memberikan materi lab mengenai Remote Span ( RSPAN ). Karena ini adalah blog lanjutan, jadi saya akan mengkonfigurasi yang hanya ada pada blog ini saja, bagi temen - temen ingin melihat konfigurasi sebelumnya ataupun blog sebelumnya mengenai BELAJAR CCNP, bisa cek link dibawah ini : https://bit.ly/37DxJrX TOPOLOGI = SW-1 SW-1(config)#vlan 100 SW-1(config-vlan)#name RSPAN SW-1(config-vlan)#exit SW-1(config)# SW-1(config)#int e0/1 SW-1(config-if)#sw trunk encap dot1q SW-1(config-if)#sw mode tru SW-1(config-if)#exit SW-1(config)# SW-1(config)#monitor session 1 source vlan 10 SW-1(config)#monitor session 1 destination remote vlan 100 SW-2 SW-2(config)#vlan 10 SW-2(config-vlan)#name PC SW-2(config-vlan)#int e0/1 SW-2(config-if)#sw mod acc SW-2(config-if)#sw acc vlan 10 SW-2(config-if)#exit SW-2(config)# SW-2(co...
