ws-c6500 flex links

[sdawson35]

Hi,

We have 2 x ws-c6506-e's and a single pix firewall, can I use the flex links comand on the 6500's to give me redundancy in case one of the 6500's fails ?

	6506 -E						6506-E
				PIX

Regards

Scott.

Hi Scott,

Genrally flex links by defination are a pair of a Layer 2 interfaces (switchports or port channels), where one interface is configured to act as a backup to the other. Flex Links are typically configured in service-provider or enterprise networks where customers do not want to run STP. Flex Links provide link-level redundancy that is an alternative to Spanning Tree Protocol (STP). STP is automatically disabled on Flex Links interfaces.

and Check out the below link on flex link configuration in 6500 switches

And for your setup i would suggest you can run redundancy protcol between 6500 serires switch with routing between pix on vip so that in case of failure one of the switch will be forwarding the traffic.

Hope to Help !!
