Issue with getting connectivity

Currently have a 3750X connected to a server at layer 3 only. Server will not communicate unless it is a routed port. Server is connected on port g1/1/1

 

interface gi1/1/1

no switchport

ip address 172.16.16.33 255.255.255.0

end

 

Required vlan for all PCs in the LAN is vlan 1280

vlan 1280 

name POAG (point of access gateway)

 

int vlan 1280

ip address 172.16.16.33 255.255.255.0

shut

 

The local domain controller is at 172.16.16.34 255.255.255.0

I cannot have the vlan 1280 as it overlaps. The PCs have been assigned the ip range of

172.16.16.39 - 62 

 

So when I have the PCs getting to the POAG they are not able to reach the domain controller (DC)

when I reconfigure I am able to get the PCs to the domain controller and not the POAG. My solution is to get a distribution switch.

 

Is there any other way to accomplish this within the same switch??

Can't you just change the IP address of gi1/1/1 to something else in between .35 - .38?

For example:

interface gi1/1/1

no switchport

ip address 172.16.16.35 255.255.255.0

Problem is you have 172.16.16.33 living in two different places on the switch, which is no good.  In fact, now that I think of it, your switch may complain if you even try to have two different IP's on the same subnet on the switch.

I would move the server to another switch and assign gi1/1/1 on that other switch an IP address other than 172.16.16.33 (such as .35).

Hello,

 

does your server connect to a bridge BVI ? If so, you could try the below:

 

bridge irb

 

interface GigabitEthernet1/1/1

no switchport

bridge-group 1

 

interface Vlan1280

bridge-group 1

 

interface BVI1

ip address 172.16.16.33 255.255.255.0

 

bridge 1 protocol ieee

bridge 1 route ip
