ME3400 - Trunk not working

[comiavs01]

Hi all, I’ am bit new to ME series switches kindly assist how should be trunking configured properly.

  I have two switches SW1 and SW2 in daisy chained (meaccess 3400 series); each has their own separate vlan. And both vlan’s in uni-vlan community and each switch has trunk ports (int gi) that allow respective vlan ID’s. Then I have set up sub-interfaces and dhcp service from the router. Vlan in SW1 is working fine and user’s receive lease IP but vlan in SW2 is not. 

thanks,

Hi again,

i have tried to create same VLAN for two switches and router is able to lease ip to devices connected to SW2

this looks issue on the port-type or vlan uni-vlan type..and i think i have missed commands 

please advise..thanks
