I have a 2 layer architecture so just a bunch of access switches, 2 redundant cores and no distribution switches. All ports are 1GB. I have 2 questions base on what I read on the SRND www.cisco.com/go/srnd
1. Is it recommend to use trunk or channel btwn access to core?
SRND seems to recommend trunks but given a recommend 20:1 ratio on the access layer, this would imply Layer 2 channels as I am using a /24 on each access switch while avoiding spanning the vlans across switches.
2. I am considering using a routed campus design, but SRND uses 1Gb in their examples. Can I use a Layer 3 channel instead?
Basically, SRND doesn't seem to recommend channels on the access layer and I am not sure why?
