Hey AtefKouiri!
The R1-2401 defaults the interfaces to access mode for VLAN 1. This means that the interface will accept all untagged frames, along with VLAN 1 tagged frames. The access mode interface will send only untagged frames. this is commonly used when connecting to edge devices, and switch interconnect on a flat network. In a network where multiple VLANs are in use, switch interconnect would be done through interfaces set to Trunk/General mode.
Here is a quick run down of the different modes.

Let me know if this helps clear things up.
Hello guys!
Am working with a DELL VRTX, with two blades PowerEdge M520 ( windows server 2012 R2 installed on both )
Every Server have 4 NICs connected to the internal switch of the VRTX,
the internal switch is connected to my network with a basic 10/100 Mbits switch
I have a flat network ( no VLANS ... )
I have also a DHCP server connected to the 10/100 Mbits switch
Problem is when i ping my DHCP server from both blades => FAILURE
Am getting APIPA Address on all of the NICs of both blades
Someone from dell told me : "you need to put the VRTX switch interface that's connected to my network switch , into a mode that will handle the frames properly by stripping and tagging them with VLAN IDs as they come and go through the interface. The easiest way would be to put the interface in access mode"
I didn't understand what he meant, what's access mode and why should i use this technique ?
Please help, thanks
