I am considering running stacked 3750 L3 switches as the edge of the network, which will connect to the ISP. The ISP would hand off two lines with one to each switch and two lines to each client zone. Does running HSRP, running port channels, or running routing protocols seem like the best option for redundancy?
Lastly, will the 3750 provide all the QoS I should need for restricting each client zone's bandwidth both up and down? Could I get away with a lower model and still get these features?
Thanks for all input!!
