Two different VLAN comminucation on the switch SG250

Hi All,

 

I would like to communicate 2 different IP block on the switch. 

Model Name : SG250-26 

 

GE5 : Vlan50 --> 192.168.5.1

GE6 : Vlan60 --> 192.168.6.1

 

Pc s connected to GE5 : 192.168.5.2

Pc s connected to GE6 : 192.168.6.2

 

Steps i did ; 

 

Created Vlans (at vlan settings under the vlan management ) Pic 1

Port vlan membership then hit the ethernet interface and join vlan (pic2, 2.2 ) 

Under IP configuration add the vlans and set up the default gateways for ports. (pic3)

 

I also tried to do that same way with CLI commands. 

 

Used some videos as references below : 

https://video.cisco.com/detail/video/5993973920001/configuring-inter-vlan-routing-on-sg250-series-switches?autoStart=true&page=1&q=router

 

I still have no connection between two VLANS i can ping from PC1 to second gateway (192.168.5.2 to 192.168.6.1)  but i can not ping to PC (192.168.6.2)

 

Does anyone know what i am missing ? 

 

thanks.

Hi @Cpsmbm ,

 

Sometimes the firewall of the PC blocks the ping of external networks.
Check that the firewalls are down when you run the ping.

Hi,

Currently, your switch is  working as L2 and you have to convert it in L3 mode with help of command:

 

"System mode router"

 

Keep in mind that you will lose the existing configuration and switch will restart.

Hey Deepak ,
I couldnt type system mode router command in putty/telnet . But from Web GUI i changed ports L2 -- L3 which doesnt work. Even i can not ping default gateway as well.

I have not used a SG250 switch but I use a SG300 switch in layer 3 mode. And I am not sure what you are calling the default gateway.  There are a couple of things which come to mind is when you assign an IP to the VLAN it becomes the gateway for the VLAN.  You also need to turn on interVLAN routing if you want access to another VLAN.

Inter routing is checked. also typed in CLI mode.
default gateways id the interface/vlan IP s.

I would start with VLAN1 the default VLAN.  Try to add a PC to VLAN1 and ping the other VLANs.  Get VLAN1 pinging VLAN50 and VLAN60.  You may discover your issue.
