Switching Tech, Lab 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.

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

        R - Layer3 S - Layer2  

        U - in use N - not in use, no aggregation          f - failed to allocate aggregator  

        M - not in use, minimum links not met  

        m - not in use, port not aggregated due to minimum links not met          u - unsuitable for bundling          w - waiting to be aggregated  

        d - default port  

        A - formed by Auto LAG
