etherchannel이 어떤 adapter로 구성되어 있고, 어떤 adapter로 통신하고 있는지 알아 봅시다. ^^
우선 etherchannel로인해 생겨난 adapter를 찾아봅시다.
#>lsdev -Cc adapter
ent0 Available 0A-08 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent1 Available 0A-09 2-Port 10/100/1000 Base-TX PCI-X Adapter (14108902)
ent2 Available 0C-08 Gigabit Ethernet-SX PCI-X Adapter (14106802)
<<<<중략>>>>
ent9 Available 0a-08 Gigabit Ethernet-SX PCI-X Adapter (14106802)
ent10 Available EtherChannel / IEEE 802.3ad Link Aggregation
위 command를 실행하면 정의된 adapter들이 display됩니다. 그중에 Etherchannel로 구성된
adapter를 볼 수 있는데요,,,,위그림에선 ent10 입니다.
다음은 ent10이 어떤 adapter들로 구성되어 있는지 살펴 보겠습니다.
#>entstat -d ent10 (결과가 너무길어 중간중간 잘랐습니다. ^^;)
굵은 부분만 확인하겠습니다.

이상 etherchannel의 구성을 살펴볼 수 있는 명령어를 살펴 보았습니다. ^^
간단히 어떤 adapter들로 구성되었는지 보고 싶다면
#>smitty etherchannel 명령으로 좀 더 간단히 볼 수 있습니다..
