Konfigurasi Etherchannel pada Cisco Packet Tracer

EtherChannel memungkinkan beberapa tautan Ethernet fisik digabungkan menjadi satu tautan logis. Jika sebuah segmen dalam EtherChannel down, lalu lintas yang sebelumnya dibawa melalui tautan yang down beralih ke yang tersisa segmen dengan di EtherChannel. Konfigurasi Etherchannel terbagi menjadi tiga jenis yaitu :

• LACP (Link Aggregation Control Protocol)
• PAgP (Port Aggregation Protocol)
• Manual

Pada postingan kali ini akan dijelaskan bagaimana mengkonfigurasi ketiga jenis etherchannel tersebut menggunakan aplikasi cisco packet tracer. 

Topologi

LACP (Link Aggregation Control Protocol)

S1

Switch>enable
Switch#configure terminal
Switch(config)#hostname S1
S1(config)#interface range g0/1-2
S1(config-if-range)#channel-group 1 mode active
S1(config-if-range)#end
S1#write

S2

Switch>enable
Switch#configure terminal
Switch(config)#hostname S2
S2(config)#interface range g0/1-2
S2(config-if-range)#channel-group 1 mode passive
S2(config-if-range)#end
S2#write

PAgP (Port Aggregation Protocol)

S2

S2>enable
S2#configure terminal
S2(config)#interface range fa0/23-24
S2(config-if-range)#channel-group 2 mode auto
S2(config-if-range)#end
S2#write

S3

Switch>enable
Switch#configure terminal
Switch(config)#hostname S3
S3(config)#interface range fa0/23-24
S3(config-if-range)#channel-group 2 mode desirable
S3(config-if-range)#end
S3#write

Manual Etherchannel

S3

S3>enable
S3#configure terminal
S3(config)#interface range fa0/21-22
S3(config-if-range)#channel-group 3 mode on
S3(config-if-range)#end
S3#write

S1

S1>enable
S1#configure terminal
S1(config)#interface range fa0/23-24
S1(config-if-range)#channel-group 3 mode on
S1(config-if-range)#end
S1#write

Kesimpulan pada postingan ini adalah konfigurasi etherchannel mempunyai 3 jenis yaitu LACP, PAgP dan Manual. Masing – masing mempunyai kegunaan dan fungsi sesuai protokol yang dipakai. Jika masih ada penjelasan yang kurang jelas bisa ditanyakan pada kolom komentar dibawah.
