Guys,

Can anyone help? I'm not a network expert so I'm a bit lost.

We just upgraded our core router from CCR1036-12G-4S to a CCR1036-8G-S2+ as we're using SFP+ on our network.

I copied over the config from the old router and everything is working fine except for some multicasting that a couple of our servers do.

One server mutlicasts to another over the internal network, so nothing special.

However, we're seeing a lot of corruption in the video.

If I change back to the old router it works fine so it's definitely related to that router.

The old router is running firmware 6.33.3 and the new one is on 6.34.

Are there any settings I should look at?

Thanks,
Cinders.

Those are RouterOS versions, check firmware versions (System > Routerboard)
