I have a wism installed on my 6513 but the moment i assign ports g12/1-4 to Po1 and Ports G12/5-8 to Po2 the are no coming up the configuration of the Ports including Po1 and Po2 are as follows:
interface range GigabitEthernet12/1-4
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 137
switchport mode trunk
switchport nonegotiate
no ip address
no snmp trap link-status
mls qos trust cos
no cdp enable
interface range GigabitEthernet12/5-8
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 137
switchport mode trunk
switchport nonegotiate
no ip address
no snmp trap link-status
mls qos trust cos
no cdp enable
wism module 12 controller 1 native-vlan 137
wism module 12 controller 2 native-vlan 137
The moment i assign the ports to their respective channel-group they all goes down, I tried to unshut them manually but no luck. IOS version is (s72033_rp-IPSERVICES_WAN-M), Version 12.2(18)SXF7.

DO you have your port channels configured correctly... also make sure you have channel-group

Port channels are configured properly, but for unknown reason the etherchannel are not coming up

Configure the channel-group and enable that first.

You have the service ports showing UP? Also, run a show etherchannel load-balance and make sure it is setup for src-dst-ip. if not run this command port-channel load-balance src-dst-ip

Yup all service ports are up, i can even access the management GUI but without the etherchannel, once i add the ports to their respective channel-group they are all switching to disabled mode.

Make sure your not using port channels 1-13, use anything above 13 and they should come up, this is a bit of a gotcha with the WiSM.
E.g Port channel
interface Port-channel20
description ***PORT_CHANNEL_WiSM_1_WLC1***
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan #
switchport trunk allowed vlan #,#
switchport mode trunk
no ip address
!
interface Port-channel21
description ***PORT_CHANNEL_WiSM_1_WLC2***
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan #
switchport trunk allowed vlan #,#
switchport mode trunk
no ip address
Interface Example
interface GigabitEthernet2/8
description ***8Gbps_GEC to Switch 2***
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
channel-group 21 mode on

If you want to get away from the port channel configuring of the WiSM, try these commands:
wism module
wism module
wism module
wism module
These statements are available on SXF5 and later, I think. I'm running 12.2(18)SXF9. (SUP720)
Here is a statement from the documentation:
Note: Software Release 12.2(18)SXF5 introduced new WiSM commands to use with auto-LAG ports (in the high 200 range). These commands can be used instead of steps 5 and 6 . Repeat the two commands for controller 1 and controller 2 in the WiSM module.
wism module
wism module

Hi Buddy, i configured port-channel 15 and 16 and the etherchannel are working fine now. the problem now is I am not able to connect to the WiSM management.

Have you setup your service port vlan? You can use it to check your management interface configurations or use the console port.
Example:
ip dhcp pool wism-service-port
network 192.168.0.0 255.255.255.248
default-router 192.168.0.1
wism service-vlan 192
interface Vlan192
ip address 192.168.0.1 255.255.255.248
end

Make sure the native Vlan for trunk on all 8 interfaces is the management VLAN tag, and make sure the management interface on the WiSM are untagged (0).
