I'd like to get everyone's thoughts on a design type question.
I currently have two 3750s acting as core switches aggregating 15-20 other access switches throughout the domain. These are NOT stacked today...they have an etherchannel between them. This is a single flat vlan today.
Within the next few days, I'll be segmenting the newtork, enabling dot1q trunking on all uplinks, etc.
My main question is around HA, STP, and uplink configuration.
Do I want to remain having two separate 3750s having one of the uplinks blocked by STP OR configure the switches for Stacking and take advantage of the active/active uplinks withi cross stack EC, OR stack but with STP still blocking one of the uplinks. I suppose it comes down to what level of redunancy is better? Two physically separate 3750s, two stacked, or are they the same in your perspective. Any software defects when stacking that could cause problems?
Any insight is greatly appreciated.
