Purchase another 3750 and stack them. Then use cross-stack Etherchannel to aggregate your access layer switches and provide active/active redundancy.

Thanks,Please could you send me links oh how to do this or if you have any Diagram or explanation you could send along .

Hi,

I've attached a link for this which you may find useful:

http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_44_se/configuration/guide/swethchl.html#wp1389988

It explains the Etherchannel failover for the 3750, including diagrams.

Please rate useful posts..

Thanks

I would like to know if Switch Stacks alone would be okay to prevent Single point of failure for distribution layer Switches. By having another cat SW3750 as you said before.

Not sure what your other concerns are here. A 3750 switch stack that is connected using redundant links using cross-stack etherchannel would mitigate against a single point of failure.

Please rate helpful posts.

Thanks

I am thinking of any failure that amy occur, be it from physical layer or power failure.

I would be glad if you can send any link or information along
