Nah sekarang perlu dicoba juga untuk yang pake standar internasional... biar gak pake punya Cisco aja.
Industri standar untuk etherchannel biasanya pake LACP (Link Aggregation Control Protocol).
Lab 5 - Etherchannel - LACP
Topologinya sih masih sama... kayak lab etherchannel PAgP.
Perangkat switch nya apa lagi...masih yang sama juga dong :)
Skenarionya menghubungkan 2 switch menggunakan etherchannel tapi pake protocol industri standar (LACP).
Konfigurasi SW1 :
SW1(config)#int fa0/1
SW1(config-if)#channel-group 1 mode active
Creating a port-channel interface Port-channel 1
SW1(config-if)#int fa0/2
SW1(config-if)#channel-group 1 mode active
SW1(config-if)#int po1
SW1(config-if)#switchport mode trunk
SW1(config-if)#channel-group 1 mode active
Creating a port-channel interface Port-channel 1
SW1(config-if)#int fa0/2
SW1(config-if)#channel-group 1 mode active
SW1(config-if)#int po1
SW1(config-if)#switchport mode trunk
Konfigurasi SW2 :
SW2(config)#int fa0/1
SW2(config-if)#channel-group 1 mode active
Creating a port-channel interface Port-channel 1
SW2(config-if)#channel-group 1 mode active
Creating a port-channel interface Port-channel 1
SW2(config-if)#int fa0/2
SW2(config-if)#channel-group 1 mode active
SW2(config-if)#int po1SW2(config-if)#switchport mode trunk
Abis di konfigure... kita cek dong di SW1... etherchannel nya apakah sudah OK :
SW1(config-if)#do sh ether sum
Flags: D - down P - in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
u - unsuitable for bundling
U - in use f - failed to allocate aggregator
d - default port
Number of channel-groups in use: 1
Number of aggregators: 1
Group Port-channel Protocol Ports

SW1(config-if)#do sh ether 1 proto

Cek juga di SW2 buat pembandingnya :
SW2(config-if)#do sh ether sum
Flags: D - down P - in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
u - unsuitable for bundling

SW2(config-if)#do sh ether 1 proto

Flags: D - down P - in port-channel
I - stand-alone s - suspended

1 Po1(SU) LACP Fa0/1(Pd) Fa0/2(P)
SW2(config-if)#do sh ether 1 proto

Yak.... akhirnya etherchannelnya udah OK.
Tuh protocol yang dipake untuk negosiasi adalah LACP.
Jadi buat LACP kalo mau aktif negosiasi... maka mode nya harus dibikin 'active'
(config-if)#channel-group 1 mode active
Video lab ini juga ada loh... mo liat nih kasih dah :
