Hi all,

I had some trouble to call dhcp  server in X620-16x-FB that act as Core Switch.  This site before, used HP3com for core switch. After convert the config into Extreme format, i failed to call dhcp server (dedicated one) for other vlan but its work for native vlan 1 that used for routing (static) between core and router. 

------------------------------------------------------------------------------------------------------------------------------------

SANGFOR : 10.112.108.254 (use for static route to core,  physical interface g3)

10.112.109.0, 10.112.110.0, 10.1128.111.0 ,(through g3 nexthop 10.112.108.253)

X620-16X : 10.112108.253 (use for static route to core,  interface vlan 1)
