etherchannel for a single vlan

man this took very long. Not so happy. I should I have given a thought earlier. But back now and I have already started to mend things. Below is an example for the configuring ether channel per vlan. I wanted to try this very desperately. For me it seemed so logically simple. Now, configuring is also simple:

The Switch 0 may be considered as Major switch which are connected to distributor switches. Here are the config of the switch 0 and switch 1. For switch 2 give it a go and try pinging 20.2 from 10.2


hostname Switch0
!
ip routing
!
interface FastEthernet0/1
channel-protocol pagp
 channel-group 1 mode auto
 switchport access vlan 10
 switchport mode access
!
interface FastEthernet0/2
channel-protocol pagp
 channel-group 1 mode auto
 switchport access vlan 10
 switchport mode access
!
interface FastEthernet0/3
channel-protocol pagp
 channel-group 2 mode auto
 switchport access vlan 20
 switchport mode access
!
interface FastEthernet0/4
channel-protocol pagp
 channel-group 2 mode auto
 switchport access vlan 20
 switchport mode access
!
interface Port-channel 1
 switchport access vlan 10  ----->configuring portchannels to a vlan
!
interface Port-channel 2
 switchport access vlan 20    ----->configuring portchannels to a vlan
!
interface Vlan1
 no ip address
 shutdown
!
interface Vlan10
 ip address 192.168.10.1 255.255.255.0

interface Vlan20
 ip address 192.168.20.1 255.255.255.0
