EtherChannel adalah fitur pada perangkat jaringan Cisco yang memungkinkan Anda menggabungkan beberapa link fisik Ethernet menjadi satu link logika tunggal. Biasanya ini digunakan dalam interface trunk (switch antar switch) yang digunakan untuk meningkatkan bandwidth atau Redundansi ===== Syntax ===== Dalam konfigurasi EtherChannel, terdapat tiga cara untuk mengkonfigurasi protokolnya dengan agregasi link menggunakan PAgP (Port Aggregation Protocol) yang merupakan protokol proprietary Cisco atau menggunakan LACP protokol standar (IEEE 802.3ad). atau juga kita dapat menkonfigurasi secara manual Static. Berikut adalah syntax dalam konfigurasi ether channel. <code> interface range <interfaces range> switchport mode trunk channel-group <number> mode <protocol> </code> Keterangan * Interface range : Interface interface yang akan di buddle * number : identifier id * protocol : protocol yang digunakan dalam ether channel Tergantung dengan mode apa yang digunakan dalam kedua link yang dapat memutuskan link terbentuk ether channel atau tidak. Berikut adalah gambar yang menunjukan bagaimana perangkat cisco bernegosiasi untuk memutuskan protokol mana yang akan digunakan. {{ :networking:cisco:cisco_etherprotocol.png?nolink |}} Contoh <code> Switch#interface range FastEthernet0/1 -
