Etherchannel between stack switches[3750] and standalone switch[3560]

Hi,

 

I have 2*3750 switches in stack as core and 1*3560 switch in access layer. I want to enable ether channel between stack switch[3750A & 3750B] and 3560 switches.

 

Have connected  2 links from 3560 switch to stack switch, one link to 3750A and other link to 3750B. Will it work in this way as per my requirement? 

 

or i should enabled stacking on 3560 switch too and configure cross-stack ether channel between 3750 stack and 3560 stack. i refered few cisco documents, but the cross stack etherchannel configuration example has 3750 at both end stacks.

 

Rgds...

Hi,  This should work fine as

Hi,

 

 This should work fine as per you set up, the 3750 stack will be acting as one switch, which means that the ether-channel configuration should be straight forward. There is no need to stack the 3560 for this to work, also the 3560 are not stackable.

 

Hope this helps.

     You can use crosstack

     You can use crosstack etherchannel on your stacked 3750's , you must use LACP as the channel aggregation method.

There is no way to stack a 3560 .
