C9300L-24T-4G-A Cisco Catalyst Fixed four-port 1G uplink with Advantage Switch

Fixed four-port 1G uplink with Advantage

C9300L-24T-4G-A is a Cisco Catalyst access switch with 24 10/100/1000 copper data ports and four fixed 1G SFP uplinks. Its A suffix selects Network Advantage; it does not change the physical port layout.

Exact port acceptance

Confirm that four fixed 1G SFP uplinks satisfy the bandwidth plan before selecting this Advantage SKU. Record oversubscription and migration needs because the similar 4X order provides 10G-capable SFP+ uplinks.

One-gigabit uplink congestion plan

Calculate the worst-case oversubscription from twenty-four access ports into four 1G SFP uplinks. Define LACP distribution, failure behavior, queue monitoring and the utilization threshold that triggers migration to a 4X or modular-uplink platform. Network Advantage adds software capability but cannot raise these cages from 1G to 10G.

License boundary

Network Advantage is the higher default perpetual Network Stack tier; verify the exact advanced routing, segmentation, resiliency and MACsec features required by the design.

Stack and power boundary

Catalyst 9300L fixed-uplink platform with StackWise-320. Data-only access ports; 350 WAC power-supply platform description. Capture PSU, fan, stack-cable and stack-power PIDs and verify the target IOS XE release before mixing members.

Receiving evidence

Record exact PID, serial, installed license state, access transceivers or copper links, every uplink optic, switch-port tests and configuration backup. Fixed-uplink C9300L models and modular-uplink C9300 models are not interchangeable based only on a shared 24-port count.
