I´m a little bit confused about the config guide ragarding box-to-box redundancy.
customer will use 2 Css 11503 and wants to configure box-to-box redundancy.
There is one advice that it is essary to link the two switches via a FE-Port. but i also fond an advice that a GE-Port can be used.
What is right? It´s depending on sw-version ?
Thank you for your help
regards

Dietrich,
initially it was necessary for this link to be FE.
With the most recent versions this link can also be a GE link.
Since this link is only being used for some kind of keepalive between the 2 CSS, I don't see the need to use GigE.
Also, unless your customer is doing firewall loadbalancing, you should really convince him to use vip/interface redundancy and not box-to-box redundancy.
You get faster failover time with vip/interface red., you can turn on statefull failover [not possible with box-to-box] and it is easier to troubleshoot.
Regards,
Gilles.
