Hi,
I'm doing centralized IP management. All client VLANs is configured as
tagged VLANs to some L2 switches using 802.1Q. All clients are
connected through the L2 switches. Each VLAN has L3 interface with
respective IP. The routing with static IP is OK.
I configure DHCP Server on S25N (firmware: 8.3.2.0) with following
scripts. The result is all clients cannot get the IP.
ip dhcp server

Beside, I cannot see following commands on the CLI.
ip dhcp bootp
ip dhcp conflict
ip dhcp database
ip dhcp filtering
ip dhcp ping
ip dhcp filtering
Please check following result.
L3A1(conf)#ip dhcp ?
relay Enable addition of option-82 in dhcp packets
server DHCP server
snooping Enable dhcp snooping configurations
After failed with configuring DHCP Server, I setup separate DHCP
Server with likely IP configuration above and use S25N as DHCP Relay.
I put DHCP Server IP on L3 interface configuration of each client VLAN
by using "ip helper-address" command. But the result, all clients
still cannot get the IP.
On first scenario, I have debuged the DHCP Server events and packets
but there is nothing happen. On the second scenario, I have captured
the traffic on DHCP Server but there is no DHCP related packet seen.
It seem that S25N doesn't listen the DHCP request from clients. How
can I deal with this problem?
Best regards,
