Problem in Trunking two 3560G

I am facing problem in trunking two 3560 G Switches.

Trunk says up but the vlan stays down.

Switch #1 3560G

interface Port-channel5
switchport trunk encapsulation dot1q
switchport mode trunk

interface GigabitEthernet0/17
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 5 mode on

Switch #2

interface Port-channel5
switchport trunk encapsulation dot1q
switchport mode trunk

interface GigabitEthernet0/4
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 5 mode on

Switch (1) is trunked with 5 more 2950 and it works just fine but for this switch (3560G) - management stays down

Is there just the one link between these two switches? If so, why the channel-group command?

Go to the physical interfaces and issue the command "no channel-group 5 mode on".

Secondly, does the VLAN exist? "show vlan brief"

Currently there exist only one link. But I plan to add one more as soon as i figure out what's wrong .

vlan exists on switch (1)
