ETHERCHANNEL LACP - SWITCHING TECHNOLOGIES #14 ( CCNP )

 SWITCHING TECHNOLOGIES #14 :

ETHERCHANNEL LACP 

 

 

 

 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 ini tabel yang bisa kita lihat untuk memahami lab berikut ini.

 

 

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
SW1(config-if)#exit

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
SW2(config-if)#exit
