OEM EOSL Calendar · Cisco
Cisco EOSL Calendar — every milestone date, every active model
Cisco maintains the most aggressive EOSL push in networking. TPM economics dominate at LDoS minus 12 months and beyond, particularly on Catalyst 3000-series, Nexus 5000/7000, and ISR 4000 platforms still running stable production workloads. WUC supports all Cisco platforms below indefinitely post-LDoS.

Catalyst (6)
| Model | End of Sale | EoSW Maint. | EoVS Maint. | LDoS | Status |
|---|---|---|---|---|---|
| Catalyst 3650 Series | Oct 30, 2019 | Oct 31, 2024 | Oct 31, 2025 | Oct 31, 2026 | LDoS soon |
| Catalyst 3850 Series | Oct 30, 2019 | Oct 31, 2024 | Oct 31, 2025 | Oct 31, 2026 | LDoS soon |
|
WUC commentary Highest TPM demand of any Cisco campus platform. Pace yourself: the StackWise-480 cluster economics make wholesale refresh expensive. Phase by stack, not by switch. |
|||||
| Catalyst 4500-X Series | Oct 30, 2020 | Oct 31, 2024 | Oct 31, 2024 | Oct 31, 2025 | Post-LDoS |
|
WUC commentary Post-LDoS as of late 2025. TPM is the only practical coverage path. Refresh candidate is Catalyst 9500. |
|||||
| Catalyst 6800 Series | Dec 31, 2018 | Dec 31, 2024 | Dec 31, 2024 | Dec 31, 2025 | Post-LDoS |
|
WUC commentary Last of the modular 6500/6800 lineage. Almost entirely on TPM by now in mid-market shops. Catalyst 9600 is the refresh target if you need chassis modularity; otherwise consolidate to 9500 fixed-config. |
|||||
| Catalyst 2960-X / 2960-XR Series | Apr 30, 2024 | Apr 30, 2028 | Apr 30, 2028 | Apr 30, 2029 | Active |
|
WUC commentary Still well-supported under SmartNet but already showing significant SmartNet renewal cost creep. TPM economics start to win at year +3 post-EoS. |
|||||
| Catalyst 9300 Series (original) | Apr 30, 2027 | Apr 30, 2031 | Apr 30, 2031 | Apr 30, 2032 | Active |
|
WUC commentary Still actively shipping in 2026. Under SmartNet, premium pricing is acceptable through ~2028 while IOS-XE feature evolution continues. Reevaluate at year +3 post-EoS. |
|||||
Nexus (5)
| Model | End of Sale | EoSW Maint. | EoVS Maint. | LDoS | Status |
|---|---|---|---|---|---|
| Nexus 5548UP / 5596UP | Jan 31, 2019 | Jan 31, 2023 | Jan 31, 2024 | Jan 31, 2025 | Post-LDoS |
|
WUC commentary Post-LDoS. Production workloads we still see on this platform: legacy FCoE storage networks, payment processing fabrics waiting for app-side migration. TPM is the only path; refresh is Nexus 9300-FX3 or Nexus 93180YC. |
|||||
| Nexus 5672UP / 56128P | Jan 31, 2021 | Jan 31, 2025 | Jan 31, 2025 | Jan 31, 2026 | Post-LDoS |
|
WUC commentary Just hit LDoS Q1 2026. Highest current-quarter TPM uptake of any Nexus platform. Pair WUC TPM with a 24-month refresh plan to Nexus 93180YC-FX3. |
|||||
| Nexus 7000 / 7700 Series | Dec 31, 2021 | Dec 31, 2025 | Dec 31, 2025 | Dec 31, 2026 | LDoS soon |
|
WUC commentary Last 12 months of OEM coverage. Modular chassis platform, common at colo and enterprise core. VDC and OTV features tie you to the platform — TPM through LDoS is the standard play while ACI / Nexus 9000 refresh planning catches up. |
|||||
| Nexus 3548-X | Apr 30, 2023 | Apr 30, 2027 | Apr 30, 2027 | Apr 30, 2028 | Active |
|
WUC commentary Latency-optimized data center top-of-rack. Common in financial services. TPM economics start to win year +3 post-EoS. |
|||||
| Nexus 93180YC-EX (original) | Apr 30, 2024 | Apr 30, 2028 | Apr 30, 2028 | Apr 30, 2029 | Active |
|
WUC commentary Workhorse leaf in many ACI fabrics. SmartNet renewal makes sense through 2027; TPM dominates after. |
|||||
ASR (2)
| Model | End of Sale | EoSW Maint. | EoVS Maint. | LDoS | Status |
|---|---|---|---|---|---|
| ASR 1001-X / 1002-X | Jan 31, 2023 | Jan 31, 2027 | Jan 31, 2027 | Jan 31, 2028 | Active |
|
WUC commentary Common WAN edge platform. IOS-XE feature roadmap is winding down. TPM at year +3 post-EoS is the right move for sites where you have no DMVPN or SD-WAN evolution pending. |
|||||
| ASR 9001 | Jan 31, 2022 | Jan 31, 2026 | Jan 31, 2026 | Jan 31, 2027 | LDoS soon |
|
WUC commentary Mid-market service provider edge. ASR 9901 or NCS 540 is the refresh target. TPM dominates from 2026 onward. |
|||||
ISR (3)
| Model | End of Sale | EoSW Maint. | EoVS Maint. | LDoS | Status |
|---|---|---|---|---|---|
| ISR 4451-X | Jan 31, 2023 | Jan 31, 2027 | Jan 31, 2027 | Jan 31, 2028 | Active |
|
WUC commentary Branch WAN router workhorse. Catalyst 8300 / 8500 is the refresh. TPM economics dominate where SD-WAN migration is deferred. |
|||||
| ISR 4431 | Jan 31, 2023 | Jan 31, 2027 | Jan 31, 2027 | Jan 31, 2028 | Active |
|
WUC commentary Mid-tier branch router. Same refresh path as 4451-X. TPM appropriate when branch SD-WAN rollout is multi-year. |
|||||
| ISR 4321 / 4331 | Jan 31, 2023 | Jan 31, 2027 | Jan 31, 2027 | Jan 31, 2028 | Active |
|
WUC commentary Small-branch routers. Catalyst 8200 is the refresh. TPM appropriate when individual branch ROI does not justify per-site SD-WAN migration. |
|||||
MDS (4)
| Model | End of Sale | EoSW Maint. | EoVS Maint. | LDoS | Status |
|---|---|---|---|---|---|
| MDS 9148S | Oct 31, 2022 | Oct 31, 2026 | Oct 31, 2026 | Oct 31, 2027 | Active |
|
WUC commentary Fabric switch in NetApp, Dell PowerStore, Pure FlashArray deployments. TPM through LDoS is standard; refresh to MDS 9148T when storage fabric speed becomes a constraint. |

|
WUC commentary Modular director-class storage fabric. Refresh target is MDS 9710 if chassis investment is worth retaining. TPM through LDoS standard practice. |
|||||
| MDS 9710 | Jan 31, 2024 | Jan 31, 2028 | Jan 31, 2028 | Jan 31, 2029 | Active |
|

|
WUC commentary Last 12 months of vendor coverage. B-Series chassis economics keep these in production well past LDoS. WUC handles B200 M4 indefinitely. |
|||||
| UCS C220 M4 / C240 M4 (rack) | Sep 30, 2022 | Sep 30, 2026 | Sep 30, 2026 | Sep 30, 2027 | Active |
|
WUC commentary M4 rack servers still common in mid-market virtualization. C220 M5 or C240 M6 is the refresh target. TPM is the standard play for any M4 still in production at LDoS. |
|||||
| UCS B200 M5 (blade) | Sep 30, 2025 | Sep 30, 2029 | Sep 30, 2029 | Sep 30, 2030 | Active |
|
WUC commentary Recently EoS. SmartNet renewal still reasonable through 2027; TPM economics win year +3 post-EoS. |
|||||
| UCS C220 M5 / C240 M5 (rack) | Sep 30, 2025 | Sep 30, 2029 | Sep 30, 2029 | Sep 30, 2030 | Active |
|
WUC commentary Largest installed UCS rack base in mid-market. Refresh target is C220 M6 or C220 M7 depending on workload density. SmartNet through 2027 is reasonable; TPM after. |
|||||
| UCS Fabric Interconnect 6248UP / 6296UP | Dec 31, 2021 | Dec 31, 2025 | Dec 31, 2025 | Dec 31, 2026 | LDoS soon |
|
WUC commentary Last 12 months of OEM coverage. FI is the critical UCS domain controller — TPM is required if any B-Series chassis or C-Series with FI uplink remains in production past LDoS. |
|||||
| UCS Fabric Interconnect 6332 / 6332-16UP | Dec 31, 2024 | Dec 31, 2028 | Dec 31, 2028 | Dec 31, 2029 | Active |

|
WUC commentary Mid-life enterprise firewall platform. Refresh target is Secure Firewall 4200 series. FTD feature-roadmap concerns push some shops to TPM earlier than the cost case alone would suggest. |
|||||
| Firepower 9300 Security Appliance | Aug 31, 2024 | Aug 31, 2028 | Aug 31, 2028 | Aug 31, 2029 | Active |
|
WUC commentary High-end modular firewall. Common in carrier and federal deployments. SmartNet through 2027 is sensible; TPM after if app-aware feature roadmap is not actively consumed. |

How to use this calendar
The 30-day fleet review procedure.
If you maintain a Cisco fleet of any size, this four-step pass yields a 36-month refresh-and-TPM roadmap.
- 1
Pull asset inventory
Export your Cisco fleet from CMDB / spreadsheet / OEM portal. Minimum columns: serial number, model, install date, support contract end date.
- 2
Map against this calendar
Cross-reference each model against the table above. Flag every unit where LDoS lands within your refresh planning horizon (typically 18–36 months).
- 3
Bucket by economics
For each model bucket: refresh-now (year +1), refresh-soon (year +2), TPM-and-hold (LDoS +1 or beyond), evaluate-app-stack (LDoS dependent on application lifecycle).
- 4
Cost-compare per bucket
For TPM-and-hold gear, compare current OEM renewal cost vs WUC TPM quote vs replacement TCO. The math typically favors TPM at LDoS minus 12 months and beyond.
Run your Cisco renewal numbers against a real alternative.
Bring four data points to a 60-minute call and we'll map your Cisco fleet sequence:
- Current Cisco asset count
- Annual OEM maintenance spend
- Contract anniversary distribution
- Asset visibility state (CMDB, spreadsheet, none)

WUC commentary
Massive deployed base in mid-market campus access. Cisco extended LDoS twice. TPM keeps these running indefinitely while you stage Catalyst 9200/9300 refresh against actual port-utilization data.
