"failover" and DHCP server in switch cisco C1300

[Isai-Roa]

Hello community.

I looking for your help to know if it is possible to create a failover on a switch C1300, I have 2 interfaces where I need to receive two different ISPs and which I must fail over, if an ISP stops responding or have connectivity that automatically switches to the second ISP, additional require to configure a DHCP server on this same SW for clients, is this possible on this SW?

The current version that it have it is: 4.0.0.91

Thank you

Hello,

If youre configuring DHCP local on the switch then you should be good there and configure it like normal. 

For the connection to 2 ISPs and switching over if one link goes down you can use a track object and/or use IP SLA with a static route referencing the interface. If the interface goes down (or the connectivity is gone, depending how you configure the track object) the track object will remove the static route and allow traffic to go to the secondary ISP.

Thanks for you reply.

I have been looking for the IP SLA command in the switch but it does not appear in the list of the commands available to execute in the SW.

And do you know where can i find more information about how to configure track object in this specific model of SW?

Apologies, I missed the C1300 model. I looked at a couple of config guides and its really limited and may not provide that functionality.

You may be able to configure a static route pointing out the preferred interface and a floating static route (higher AD configured) pointing out the secondary interface to meet your requirements.

Hello
two isp circuits connected to a switch performing dhcp?

can you elaborate a lillte on your intended/current topology please?

Dhcp for clients not effect by ISP failover 

If you can not run ip sla, then config two static route with dhcp keyboard (without set next-hop) and make one of static route have higher AD than other.

Note:dhcp in static route is use for SW get IP from ISP not for SW clients
