Cisco Nexus 9372PX vs Nexus 93180YC-FX
The 9372PX is a first-generation 10G leaf; the 93180YC-FX is the cloud-scale successor with 25G downlinks, 100G uplinks, MACsec and unified ports. For new leaf builds or a 9372PX refresh, move to the 93180YC-FX.
Cisco Nexus 9372PX
First-generation 1RU leaf switch with 48 SFP+ 10G server ports and 40G uplinks for NX-OS or ACI fabrics.
- 48x 1/10G SFP+ downlinks plus 6x 40G QSFP+ uplinks
- 1.44 Tbps switching capacity, 1150+ Mpps
- T2-class ASIC; runs NX-OS or as an ACI leaf
- Now superseded by cloud-scale FX leaf switches
Cisco Nexus 93180YC-FX
Cloud-scale 1RU leaf with 25G unified downlinks, 100G uplinks, MACsec and FCoE/Fibre Channel options.
- 48x 1/10/25G SFP28 downlinks plus 6x 40/100G QSFP28 uplinks
- 3.6 Tbps switching capacity, sub-microsecond latency
- Cloud Scale ASIC with line-rate MACsec
- Unified ports support 16/32G Fibre Channel and NX-OS or ACI

Choose Cisco Nexus 9372PX if
Keep the 9372PX only where it is already racked, your servers stay at 10G, uplinks stay at 40G, and you do not need MACsec, 25G, or Fibre Channel on that leaf.
Choose Cisco Nexus 93180YC-FX if
Choose the 93180YC-FX for new leaf deployments or a 9372PX refresh when you want 25G server ports, 100G uplinks, MACsec, and the option of unified Fibre Channel ports.
Verdict
The 93180YC-FX is the cloud-scale replacement for the 9372PX, roughly 2.5x the fabric with 25G downlinks, 100G uplinks, MACsec and Fibre Channel flexibility. Migrate to the FX leaf for new builds; only keep a 9372PX short-term where 10G access is sufficient and budget defers the refresh.
Frequently asked questions
What replaced the Cisco Nexus 9372PX?
The cloud-scale Nexus 9300-FX family, specifically the 93180YC-FX, is the modern leaf replacement, adding 25G downlinks, 100G uplinks and MACsec.
Can both the 9372PX and 93180YC-FX run ACI?
Yes. Both can operate as Cisco ACI leaf switches or in standalone NX-OS mode, but the 93180YC-FX adds cloud-scale features like MACsec and 25G access.
Does the 93180YC-FX support Fibre Channel?
Yes. Its unified ports can be configured for 16/32G Fibre Channel and FCoE, which the 9372PX does not support.
Is upgrading from 9372PX to 93180YC-FX worth it?
If you need 25G server connectivity, 100G uplinks, encryption, or storage convergence, yes. If your rack is purely 10G with no encryption requirement, the upgrade can be deferred but the platform is end-of-sale.
