Many midsize and large networks face the problem of growing traffic that outpaces older equipment. When the network cannot keep up, applications lag, video calls drop, and employee frustration rises. This matters because downtime directly hurts revenue and reputation. The Catalyst 9500 solves the issue with 48 ports that support 1/10/25 Gbps speeds, four 40/100 Gbps uplinks, and a powerful UADP 3.0 ASIC that delivers up to 3.2 Tbps of switching capacity. The result is a smooth, future-ready network that scales with your needs.
