eNSP fails to deliver the DHCP reply over stacking VLAN

Hi

please check attachment, i have attached my ENSP files

could you please load it to your ENSP to check what is wrong with my configuration

thanks for your help

PS

Client 1 should get ip address over DHCP from R1

if you capture packets in R1 interface you will see that DHCP discovery comes from client 1 but there is no replies

Hi

thanks a lot it works

Hi,which device is on dhcp relay?

Hi, thenks for your reply

there is no any relay since it is plain L2 network from the PC to the DHCP server, only betwean LSW3 and LSW1 the customer vlan 10 stacks with the ISP service vlan 500 which is later removed by untag vlan 500 on LSW1 eth0/0/3. then the DHCP request packet with vlan tag 10 comes to R1 eth 0/0/0 where vlan tag 10 terminates eth 0/0/0.10

#
interface Ethernet0/0/0.10
dot1q termination vid 10
ip address 192.168.0.1 255.255.255.0
dhcp select global
#

so the problem using wireshark on Ethernet0/0/0.10  i can see DHCP discover packeges from PC1 arriving but no any replies from R1

if i delete interface Ethernet0/0/0.10
and configure like

nterface Ethernet0/0/0
port lik-type trunk
port trunk allow pass vlan 10

interface vlan-if 10
ip address 129.9.0.1 255.255.255.0
dhcp select global

then it works all right

Hi,

I  made the config for R1,it works.

#
interface Ethernet0/0/0
undo portswitch
undo mac-address
