BIG IP to server - what cable should be used

Hello I have BIG IP 6400 configured... Am I right that ports need to be connected to servers with crossover cables (not as usually straightforward cables?)

I don't have access to an F5 manual, but based on past experience with load balancers, the only time you might need a crossover cable is when interconnecting two load balancers. The connections from the servers should be standard straight-thru cables.

Hi.
I have now more clear :)
If you set up 100 full duplex then you need crossover cable to connect servers.
If you set up auto then you can use normal lan cable...

Modern devices have autoinvert capacity :-)

Yes, most newer Hubs, Switches, and Routers have the Auto-MDIX feature. This enables a device to connect with either a straight-thru or a crossover cable. However, I worked on a new FOUNDRY load balancer about 2 years ago and it did NOT have Auto-MDIX.

Some NICs have the feature, but it is not an "across the board" feature for PCs and Servers yet (they may have it if they have a 10/100/1000 interface).
