Our department recently purchased new WS-C2960S-24TS-L switches to act as our cabinet switches. However, these will be uplinked into existing WS-2960S-24TS-L that act as the aggregation switches.
What are our options for connecting these switches together? The uplinks on the cabinet switches are SFP while the ports on the aggregate switches are normal RJ-45 gig-e ports.
Thank you.
