SG300-28P - Inter-Vlan routing

Dear All,

I am new at this forum and need help to configure my new SG300-28P.

When I have started the switch, I have specified a new password and enabled telnet in order to setup the switch in Layer 3 mode.

After a restart, the switch took its IP address from a DHCP server.

When I try to set a static IP address (192.168.2.1), I receive the following error message:

Duplicated IP interface on the same subnet.

The IP address 192.168.2.1 is not used by any device within the network.

For informations, the message doesn't appear when the switch is in Layer 2 mode.

Could you please explain me why I can't change the IP address of default vlan in Layer 3 mode ?

All I can do is set the IP address to static or dynamic.

For test purpose, I have added 2 vlans. But I wasn't able to route traffic between vlan.

Can someone explain me how to configure the switch to route traffic between vlan?

Please find below details informations about my VLANs.

     - Default (VLAN ID 1)

IP Address : 192.168.2.1

Subnet : 255.255.255.0

     - Private (VLAN ID 10)

Switch IP address : 192.168.10.1

Subnet : 255.255.255.0

     - Public (VLAN ID 20)

Switch IP address :192.168.20.1

Subnet :255.255.255.0

Kind Regards,

Zubair.

SG300-28P - Inter-Vlan routing

I have managed to set the IP Address for default Vlan.

I have connected a client to VLAN 10 and deleted the interface for VLAN 1

Then I have created a new interface for VLAN 1 with the IP address : 192.168.2.1

I still have issue routing the traffic between VLANs.

From a client within VLAN 10, I can ping the interface of other VLANs. But I can not ping client within other vlans.

Please find below details informations about my VLANs.

     - Default (VLAN ID 1)

IP Address : 192.168.2.1

Subnet : 255.255.255.0

     - Private (VLAN ID 10)

Switch IP address : 192.168.10.1

Subnet : 255.255.255.0

     - Public (VLAN ID 20)

Switch IP address :192.168.20.1

Subnet :255.255.255.0

SG300-28P - Inter-Vlan routing

Are the PC client in the VLANs using their VLANs  switch IP address as their default gateways ?

If yes is the answer the switch itself will switch IP packets between VLANs.

If no, I wonder what firmware you are using on your switch ?

HI zubair,
