HI,
I can give you some tips to troubleshoot this
1) Configs for ports are correctr 0/0/0 0/0/1 0/0/2 and 0/0/3.
2) Even trunk config is correct.
When you are saying DHCP is not working , we should check the device connected to 0/0/47 and its configuration.
Where is the DHCP server connected to, if its on the device connected to 0/0/47 check the relay or server config.
You could also do "monitor traffic interface ge-0/0/47 no-resolve" and check if dhcp packets are going out, if they are going out the problem is not on EX2200 but on the next hop.
You may as well open a TAC case to troubleshoot if you feel so.
Thanks
Partha
