ETHERCHANNEL L3 - SWITCHTECH #15

 

ETHERCHANNEL L3 - SWITCHTECH

Perhatikan topologi berikut ini,

Kalo kita lihat pada lab-lab sebelumnya semua etherchannel berjalan pada layer 2 dan kali ini kita akan rubah agar etherchannelnya berjalan dilayer 3, untuk topology masih sama kita kemudian Konfigurasikan EtherChannel Layer 3 antara SW1 dan SW2 tanpa melakukan negosiasi protocol,

SW-1

SW1(config)#interface range e0/0-2 

SW1(config-if-range)#no switchport 

SW1(config-if-range)#channel-group 1 mode on

Creating a port-channel interface Port-channel 1

!

SW1(config-if-range)#Interface port-channel1 

SW1(config-if)#no switchport

SW1(config-if)#ip address 12.12.12.1 255.255.255.0

kemudian di lanjutkan ke konfigurasi di router - 2

SW-2

SW2(config)#interface range e0/0-2 

SW2(config-if-range)#no switchport 

SW2(config-if-range)#channel-group 1 mode on

Creating a port-channel interface Port-channel 1

!

SW2(config-if-range)#Interface port-channel1 

SW2(config-if)#no switchport

SW2(config-if)#ip address 12.12.12.2 255.255.255.0

Verifikasi, 

SW-1

SW1#show etherchannel summary

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

terakhir cek ping, 

SW-1

SW1#ping 12.12.12.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 12.12.12.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/16 ms
