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)

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

last config on HP3com:

[CoreSwitch]dis current-configuration
#
sysname CoreSwitch
