Stack of 2910 Trunk to one 2910

[Tobias_K]

Hi There

I have a problem with a Stack.

There is a Stack of two 2910al 48p  ( I call them switch a and b) and one 2910al 48 (called switch c)

Now i want to connect Port a48 with c48 and b48 to c47.

a48 -----------------  

    |                             |c48  / c47

b48 -----------------   

What do i have to do? There are 3 VLANs 1, 2, 3

When i Activate LACP active on the C switch on Port 48 and 47.

What do i have to do on a and b?

Thank you very much for a fast Answer!! :)

hi..

the hp stacking with the 2910 switch is not stacking as you might know it from cisco.

you can't linkaggregate ports from different switches(a,b).
