etherchannel配置

手动配置etherchannel
S1
interface port-channel 1
exit
interface range gigabitEthernet 0/1-2
channel-group 1 mode on
switchport trunk encapsulaition dot1q
switchport mode trunk 
exit
 
port-channel load-balance dst-ip
 
S2
 
interface port-channel 2 两边的编号可以不一样,只是本地有效而已
exit
 
interface range gigabitEthernet 0/1-2
channel-group 2 mode on
switchport trunk encapsulation dot1q
switchport mode trunk
exit
 
port-channnel load-balance dst-ip
 
 
配置pagp 和lacp
 
S1
interface port-channel 1
exit

channel-procotol pagp
channel-group 1 mode desirable
switchport trunk encapsulaiton dot1q

interface port-channel 2
exit
 
interface range gigabitEthernet 0/1-2
channel-procotol pagp
channel-group 2 mode auto 
switchport trunk encapsulation dot1q
