How to configure etherchannel load-balance in the middle switch
Hi, Experts,
Assume there are 3 catalyst switches 3550 connected to each other in triangle with Etherchannels. Cat1 is the root of spanning tree.
A workstation is linked to Cat3. The major user traffic is between the workstation in Cat3 and the users in a Vlan in Cat2. In this topology, the traffic goes from Cat3 ->Cat1 -> Cat2 and back from Cat2 -> Cat1 -> Cat3, because Cat1 is the root of the spanning tree.
Cat1 / / Cat2 — Cat3
In Cat 3 : port-channel load-balance dst-mac
In Cat 2: Port-channel load-balance src-mac
My question is:
- How to configure etherchannel load-balance in the middle switch Cat1, which is in the middle of traffic path?
- Should I change the Root switch to either Cat2 or Cat 3, to make the traffic travels between Cat2 and Cat3 without passing Cat1 ? It will use the etherchannel bandwidth more efficient.
Thanks in advance
Frank
