TL-SG105E DHCP Forwarding issues on latest firmware
2014-12-30 07:09:12
Region : UnitedStates

Model : TL-SG5428

Hardware Version : V1

Firmware Version :

ISP :


I have a Meraki Core switch with a TP-Link TL-SG105E in my office. I have setup VLAN 2 for another device and have a DHCP server on Vlan2.

I set port 1 as a MTU port
I'm running .1Q with ports 1 &5 in VLAN 2
I have setup PVID on port 5 to VLAN 2
Default VLAN 1 is on both sides of VLAN trunk port

DHCP reply is never received on port 5

FROM Meraki Side:
I see vlan trunk enabled, I see two vlans 1 &2, I see my device send a DHCP request on vlan 2
I run a packet capture on the Uplink port to TL-SG105E. It is recieving the DHCP reply from the DHCP server on Vlan 2. reply is never recieved on port 5 of TL-SG105E.

I upgraded to latest firmware.

What am I missing?

Thanks
Brian

Don't use MTU VLAN. Use tag VLAN

Have you configured the private VLAN or sth else on your Meraki? If you could make sure you capture the DHCP reply sent from Meraki but only to find TL-SG105E abandoned it, you should concern more about the relay, if it fits the standard dot1.q format.
