SF300 ip route

[Fida jlassi]

Hi all,

bellow is what I need to do with the SF300 switch:

I will integrate a cisco switch SF300 to support the failover between GPRS and 3G netwoks between two different sites.

To simulate the installation in our plateform, I put the cisco SF300 linked to three computers to simulate the 3G , the GPRS and the internal connexions. could you please provide a procedure to start this work.

NB: I start with a simple configuration; create 3 vlans then I did the ip route between the vlans the problem is that with the ip route it's not possible to ping  from one vlan to another, I did the same work with the cisco catalyst and it works but with the SF300 I don't know what's the problem exactly.

Could you help please with this?

Regards,

Hi Fida, if the intervlan communication does not work it sounds like your host connection default gateway are not pointing to the IP address of the VLAN on the SX300 switch. The switch will make IP routes automatically when you assign an IP to the VLAN interface.

Fida, if you intend to do inter-vlan routing on the switch you need to put in layer 3 (router) mode.  then as Tom mentioned make sure the default gateway for devices on each VLAN are the IP assigned to that VLAN in the switch (SVI).

CLI to do this is:

switch706852#set system mode router

When you change modes config is erased so keep that in mind.

Hi Brandon,

I opened a thread in the following link

https://supportforums.cisco.com/message/4081881#4081881 concerning  the configration of the failover between two lines.

I included also the architecture for more details.

Please Can you advise on how to configure tha layer 3 switch cisco SF300 in my case, cause I start the configuration of the IP route but it doesn't work in my case (can't ping the two router).

This is unsupported on the small business switches.

Hi Tom Watts ,

Can you advice please on how to configure the Cisco layer 3 switch according to the architecture that you can find in this link https://supportforums.cisco.com/message/4081881#4081881.

And which switch will be suitable to my application?

Hi,

Is the main request in this post to establish L3 connectivity?

If so, as stated above, configure the switch to be in router mode. 

Configure IP addresses on the the three VLANs' interfaces.  Ensure the VLANs are up (active trunk or host port).  Check you have IP connectivity to the switch virtual interfaces.  If the switch is the default gateway for the devices on each VLAN, you will have basic connectivity VLAN to VLAN.

See the following post for more details:
