THERCHANNEL LACP - SWITCHTECH #14

 

THERCHANNEL LACP - SWITCHTECH


Perhatikan topologi berikut ini,


Untuk lab ini menggunakan LACP Etherchannel, LACP ini etherchannel Open Standard jadi di vendor lain ada. Mode yang bisa digunakan untuk membentuk etherchannel LACP ada 2 yaitu :

- Active
- Passive

Kedua Mode ini bisa digunakan tapi ada syaratnya jika mode Passive dan Passive ketemu maka tidak akan membentuk etherchannel sama sekali,

Berikut konfigurasinya,

SW-1
SW1(config)#interface range e0/0-2
SW1(config-if-range)#channel-group 1 mode active
Creating a port-channel interface Port-channel 1 
!
SW1(config-if-range)#interface port-channel 1 
SW1(config-if)#switchport trunk encapsulation dot1q 
SW1(config-if)#switchport mode trunk


SW-2
SW2(config)#interface range e0/0-2
SW2(config-if-range)#channel-group 1 mode passive 
Creating a port-channel interface Port-channel 1
!
SW2(config-if-range)#interface port-channel 1 
SW2(config-if)#switchport trunk encapsulation dot1q 
SW2(config-if)#switchport mode trunk

Verifikasi,
