hi.
4404 controller has 4 port.
ap of 100 is connected to the 6509.
topology is below
4404 controller----6509------100 ap.
all of ap is same subnet. vlan1
when 4 port of 4404 is connected 6509,
how do i configure 4 port of 6509 sides ?
Do I configure 4port etherchannel?
Do I configure each port of 4port trnuk ?
etherchannel + trunk?
thanks for in advance your help.

I would enable Link Aggregation on the wlc. Then I would configure the switch port as a dot1q trunk and bundle them in an etherchannel.
interface GigabitEthernet2/0/1
switchport trunk encapsulation dot1q
switchport trunk native vlan x
switchport mode trunk
channel-group 1 mode on
!
interface GigabitEthernet2/0/2
switchport trunk encapsulation dot1q
switchport trunk native vlan x
switchport mode trunk
channel-group 1 mode on
!
interface GigabitEthernet2/0/3
switchport trunk encapsulation dot1q
switchport trunk native vlan x
switchport mode trunk
channel-group 1 mode on
!
interface GigabitEthernet2/0/4
switchport trunk encapsulation dot1q
switchport trunk native vlan x
switchport mode trunk
channel-group 1 mode on
!
interface Port-channel1
switchport trunk encapsulation dot1q
switchport trunk native vlan x
switchport mode trunk
!
Hope this helps.

We set up 2 440s's in LAG using ether-channels. Here is an example of our configuration for the ehterchannels and the ports.
interface Port-channel10
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
no ip address
exit
interface Port-channel11
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
no ip address
exit
interface GigabitEthernet8/43
no description
no switchport access vlan
description etherchannel 4402-1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 10 mode desirable
exit
interface GigabitEthernet9/43
no description
no switchport access vlan
description etherchannel 4402-1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 10 mode desirable
exit
interface GigabitEthernet8/44
no description
no switchport access vlan
description etherchannel 4402-3
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 11 mode desirable
exit
interface GigabitEthernet9/44
no description
no switchport access vlan
description etherchannel 4402-3
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 11 mode desirable
exit
exit

You should configure channel-group 11 to "on" not desirable.
Note When a 4404 controller or WiSM controller module LAG port is connected to a Catalyst 3750G or 6500 channel group employing load balancing, note the following:
â¢LAG requires the etherchannel to be configured for the "on" mode on both the controller and the Catalyst switch.
â¢Once the etherchannel is configured as "on," at both ends of the link, it does not matter if the Catalyst switch is configured with either Link Aggregation Control Protocol (LACP) or Cisco proprietary Port Aggregation Protocol (PAgP) because no channel negotiation is done between the controller and the switch. Additionally, LACP and PAgP are not supported on the controller.

good tip. Thanks

Can this be split between to switchs?
08-22-2008 04:43 AM
Usuall not unless you have a newer switch that supports etherchannel between switches or blades.

i have two 6513s with sup720

Sorry, I forgot to include the port channel settings.
interface Port-channel10
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
no ip address
exit
interface Port-channel11
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
no ip address
exit
