What changes at EOSL
The Catalyst 3650 keeps working. Cisco just stops answering.
End of service life is the date Cisco stops selling support contracts for the Catalyst 3650. It is a commercial decision, not a technical one. The network still runs, its failure modes are well documented, and spares are available on the secondary market.
We keep Catalyst 3650 spares in stock and support the platform for 3 to 5+ years past October 31, 2026 with in-house L3+ engineers 24/7/365, a 4-hour on-site SLA, and month-to-month terms. Most customers use that window to refresh on their own schedule instead of Cisco's.
