CSS Design question

Hi All,

I have a couple of questions around the CSS 11501 would be grateful if any gurus out there cud shed more light, here goes;

-Does the CSS support bridging between 2 vlans? In a similar way to the CSM. What command might be used to achieve this?

Thanks.

Kind Regards,

The CSS will bridge physical interfaces that belong to the same circuit vlan.

Nothing special to do. Just configure the same vlan on 2 physical interfaces.

Thanks for your response Giles.

Gotcha, further more ... so if CSS is L-2 adjacent to the servers do the servers have to have loopbacks created for the VIP?

I wud assume this wud be required as the CSS will only be re-writting the MAC address? Can you please shed more light here as well.

Cheers

no, there is no need to configure a loopback on the server.

By default the CSS does a destination ip re-write/nat using the server ip.

Even if they are adjacent.

However, if you want to avoid the ip nating, you can change the service type to transparent-cache.
