Hello,
I am configuring vlan on sg300-20 in dhcp mode.
One vlan (5) that is directed connected to the adsl router get ip address and when I connect host to the ports in this vlan they also receive ip address and can go on internet.
The other four vlans dhcp status are not received
Kindly help me check this. Thanks

I also do not understand why the ip address is 0.0.0.0/32.
Becuase the dhcp address 192.168.3.1/24
Thanks.

Hi Audio, looks like you're probably missing some static routes on your router or if the router supports it, 802.1q vlans and a trunk connection.

Hi Tom,
You mentioned i am missing some static routes on the router.
If you do not mind to point it out to me exactly what to correct.
Thanks.

Hi Audio, from what I can tell, you have your vlan interfaces set up to receive DHCP from something. The vlan interfaces have not received DHCP or have a configured IP on them. If this is your intention, your DHCP server does not have any method to assign those interfaces an IP address.
If this is not your intention, what is it? Are you trying to get the switch to assign IP addresses to connected clients on a vlan?

Hello Tom,
Yes i can feel you taking me toward the solution.
Actually I have an ADSL router that has DHCP capability and my vlan interfaces are to receive ip address from it.
The adsl router Ip address is 192.168.3.1
Vlan 5 WAN which is directly connected to the adsl router get Ip address while the other vlan do not.
When I assign port from other vlan to vlan 5 and I attach host to the port they get ip address and go on internet. The strange thing is that the other vlan do not get ip address. Thanks.

Hello Audio,
I do not see the address pool for other vlans. Please create separate address pool. Also associated those address pool to the VLANs.
Please feel free to contact me if you have any queries.
Thanks and regards,
Siva

I am not sure I get you correctly, where do I need to create the address pool?
In the router or in the switch?
Do I need to create it for each vlan?
Kindly explain. Thanks
