Cisco Catalyst Sup 7L-E vs Catalyst 9400 Sup-1
The WS-X45-SUP7L-E is the Catalyst 4500E supervisor; the C9400-SUP-1 is the Catalyst 9400 supervisor that replaces it. The 9400 Sup-1 nearly doubles per-slot bandwidth, runs IOS XE with programmability and SD-Access, and is TAA-compliant and actively supported, making it the migration path for end-of-life 4500E platforms.
Cisco Catalyst 4500E Supervisor Engine 7L-E
Legacy Catalyst 4500E supervisor for borderless campus access and aggregation.
- 520 Gbps system, 48 Gbps per slot
- 2x 10 GbE (SFP+) or 4x 1 GbE (SFP) uplinks
- Classic IOS software
- End of sale and approaching end-of-support
Cisco Catalyst 9400 Supervisor Engine-1
Current Catalyst 9400 supervisor built on UADP 2.0 and IOS XE for the modern campus.
- 1.44 Tbps system, 80 Gbps per slot
- 8x 10G SFP+ or 2x 40G QSFP+ uplinks
- Cisco UADP 2.0 ASIC with MACsec-256 hardware encryption
- IOS XE with programmability, model-driven telemetry, SD-Access

| Lifecycle status | End of sale | Current / shipping |
Choose Cisco Catalyst 4500E Supervisor Engine 7L-E if
Keep the Sup 7L-E only to sustain an existing 4500E chassis short-term while a 9400 migration is planned and funded. It still serves campus access and aggregation but is end-of-sale and nearing end-of-support.
Choose Cisco Catalyst 9400 Supervisor Engine-1 if
Choose the C9400-SUP-1 for any new chassis or modernization. It nearly doubles per-slot bandwidth, runs IOS XE with programmability and SD-Access, adds MACsec-256, and offers TAA-compliant options for federal procurement.
Verdict
Migrate from the 4500E Sup 7L-E to the Catalyst 9400 Sup-1. The 9400 supervisor delivers far higher per-slot and system bandwidth, the UADP 2.0 ASIC, IOS XE with full programmability and SD-Access, and MACsec-256, on an actively supported, TAA-compliant platform. Because the 4500E line is end-of-sale, plan the chassis-and-supervisor refresh rather than reinvesting in 4500E.
Frequently asked questions
Is the Catalyst 4500E Supervisor 7L-E end of life?
Yes. The Catalyst 4500E platform, including the Sup 7L-E, is end-of-sale and is progressing through Cisco's end-of-support milestones. New deployments should move to the Catalyst 9400.
What replaces the Catalyst 4500E Supervisor 7L-E?
The Catalyst 9400 Supervisor Engine-1 (C9400-SUP-1) is the modern successor. It runs on the Catalyst 9400 modular chassis with UADP 2.0 and IOS XE.
Can the C9400-SUP-1 go into a 4500E chassis?
No. The C9400-SUP-1 is a Catalyst 9400 supervisor and requires a Catalyst 9400 chassis (C9404R, C9407R, or C9410R). Migration means moving to a 9400 chassis, not just swapping the supervisor.
Is the Catalyst 9400 Sup-1 TAA-compliant for federal buyers?
Yes. The Catalyst 9400 family is offered in TAA-compliant configurations suitable for US federal procurement and is GPC-payable through an authorized partner.
