X1018 dhcp relay.

Bom dia, estou tento dificuldades com o sw da dell o x1018, meu cenário é este:

Servers vlan 1

10.0.3.0/28

Mask

255.255.255.240

Hosts 14

10.0.3.1 - 10.0.3.14

 

Estacoes vlan 2

10.0.4.0/26

Mask

255.255.255.192

Hosts 62

10.0.4.1 - 10.0.4.62

 

Uso o esxi 6.5 na porta 2 do sw, e esta como trunk e vlan 2 T.

Ja configurei o dhcrp relay no sw, porém as estacoes n conseguem pegar IP.

Devo fazer alguma outra configuracao no sw? 

OBS: Testei por um vm e coloquei a vlan 2  no virtual switch no esxi e funcionou, pegou IP.

Is the ESXi server configured to send tagged packets?

yes, is configured to send T packets.

Where does the DHCP server reside on the network?

Is a windows server VM on vlan 1 and is dhcp server.

Vlan 2 is computers workstation.

I did the test with a VM windows and get normal IP by DHCP server on VLAN 2. O my switch I configured dhcp relay and point to dhcp server.

The workstations that are not able to obtain an IP address, are they also virtual machines?

Yes, is windows vm, only for test...and get ip from dhcp server.

I tested on standalone windows direct plugged on switch and nothing get ip..today I will test with static ip and ping the dhcp server..

I'll post here.

If the workstations is a standalone workstation, it will need to connect to an interfaces that is configured as untagged for VLAN 2.

I tested and not get ip..i'll  put static ip today for testing ping.

If the client requesting the address is a VM, then the Vswitch will need to be configured to place the VM traffic into VLAN 2.

In vm works great, get ip from dhcp.

I don't use ACL.

Later I put result here.

Hi, I did the test, I put static ip on standalone windows and works, I can ping dhcp server, use internet, but didn't get ip from dhcp.

I don't know why.

I make the test with wireshark, but when I change workstation port on switch to vlan 2, dhcp doesn't work...I don't know why. I have other switch like HP work great.

Hi,
-It is not supported on IPv6.
It is IPv4.
-It is not relayed to servers on the client’s VLAN.
Dhcp server is on VLAN 1 default, VLAN 2 is for client's.
-Packets that have option-82 information, added by other devices, are discarded.
Not used!
   -It does not support Option 82 on non-VLAN interfaces.
   -It can be enabled only on a VLAN/Port/LAG that has an IP address defined on it.
It enable on VLAN 2 with 10.0.4.1 subnet.

Do you have a nonVM workstation/server you could configure as a test DHCP server?

I don't have nonVM to test!

I will reboot the switch again for testing...
