Curation Review
✔ Pros:1 Tbps StackWise-1T stacking with up to 8 members; 25G SFP28 uplinks on 24Y and 12Y models; 10G multigigabit UPOE+ downlinks on HX models; Layer 3 managed switching; high switching capacity (1,760-2,000 Gbps)
✘ Cons:High list price (MSRP roughly $15,000-$23,000 for 24- and 48-port models, reseller pricing lower); spec figures differ across Cisco datasheet versions, so verify against the current Cisco datasheet before purchase; 48-port PoE budget not confirmed; mixed stacks with standard Catalyst 9300 drop to StackWise-480 speeds; Network Essentials vs. Network Advantage licensing adds cost and changes features; meaning of the -E and -A SKU suffixes not confirmed in sources
