I'm looking for some advise on my network up-link configuration.
I have single Cisco 6500 series acting as a core/distribution switch in my network. Its Equipped dual Supervisors and multiple 1gig line cards.
My access switches are primarily Cisco 2900 Series in a stacked configuration. Each switch stack has 2 up-links back to the 6500 Core and i am curious what is the best approach to configuring these up-links is ?
should i port-group these trunk links and create a cross-stack Etherchannel ? does this have any implications / downsides ?
or should i simply leave them as independent up-links and allow Spanning-Tree to control them.
