Cisco 3560 Replacement - new switch will not pass traffic -

We had a 3560G overheat and we replaced it , In this switch replacement we experienced two issues....

while copying over the config one command didnt work on the new switch. "control-plane" it looks like it was pulled from the new version of IOS on the replacement switch.
and second the switch was not passing traffic across the Trunk ports connecting to the other half of the network

attached is the config of the new switch. do i need to issue a command to allow network traffic back across the path?

Can you post a draft of your topology? Also you're missing an attachment ;)

Without the attachment my first suggestion would be to check the trunk port and make sure that it is cabled properly and that it is set to allow all the VLAN's you want to be able to pass through it.

their is connection link is Up up
Steven CarnahanNetwork ManagerCommented:
You have ports G0/23 thru G0/28 configured as Trunk ports.  The only ones with a VLAN assigned are G0/23 and G0/27 and they are both set to VLAN 20 (default).  

I don't see where you are allowing VLAN 123 through any of the trunks.

     switchport trunk allowed vlan 123, 124

needs to be added to your actual trunk port.
