C9610-LC-32CD Description
C9610-LC-32CD is a Cisco C9610 Series Smart Switches combo line card for the C9610R modular chassis, used to add high-density QSFP fiber connectivity in campus core, distribution, or edge designs. It provides 30 QSFP28 ports for 100G/40G and two QSFP-DD ports for 400G/100G/40G, works with C9610-SUP-3 and C9610-SUP-3XL supervisors, is supported in C9610R line-card slots 1, 2, 3, 4, 7, 8, 9, and 10, and is introduced with Cisco IOS XE 17.18.1.

Application Scenarios
Use C9610-LC-32CD when a C9610R chassis needs a QSFP-heavy line card for 100G or 40G core, distribution, or aggregation links and the design does not require SFP56 port density on the same module.
Select this line card when the port plan includes QSFP-DD 400G uplinks from a C9610R system. Cisco documents operating modes that preserve 100G density while allowing one or two 400G QSFP-DD connections.
Choose C9610-LC-32CD when the project wants a native C9610 line card instead of installing a Catalyst 9600 Series line card through the C9610-LC-ADPT adapter.

- C9610-LC-32CD is the native C9610 option for QSFP-heavy designs where 100G/40G density and 400G QSFP-DD uplinks are the main requirement.
- C9610-LC-40YL4CD is the better native C9610 comparison when the same chassis needs 50G/25G/10G/1G SFP56 density plus QSFP uplinks.
- C9600X-LC-32CD is close in port role, but C9610R use requires the C9610-LC-ADPT adapter, so it should be checked separately in migration or installed-base BOM checks.
- For price and order checks, treat optics, supervisor selection, software release, adapter use, support coverage, and global deployment as separate approval items.
Selection Guide
1. Choose it for QSFP-heavy C9610R designs
Select C9610-LC-32CD when the design requires a native C9610R line card with high-density 100G/40G QSFP28 capacity and documented QSFP-DD 400G modes.
2. Choose 40YL4CD when SFP56 density matters
Move to C9610-LC-40YL4CD when the port plan is mostly 50G, 25G, or 10G SFP56 connections and only a smaller QSFP uplink block is required.
3. Separate native line cards from adapter-based line cards
When comparing C9610-LC-32CD with C9600X-LC-32CD, confirm whether the project is ordering a native C9610 line card or reusing a Catalyst 9600X line card through C9610-LC-ADPT.
4. Validate optics and software before purchase
Confirm Cisco-supported QSFP28 and QSFP-DD optics, the required 400G or 200G mode, Cisco IOS XE release, and supervisor module type before the bill of materials is approved.
Ordering Checklist

Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact SKU |
Confirm C9610-LC-32CD |
Separates the native C9610 32CD line card from the C9600X-LC-32CD adapter-based option |
|
Chassis |
Confirm Cisco C9610R |
This line card is documented for the C9610R modular chassis |
|
Supervisor Module |
Confirm C9610-SUP-3 or C9610-SUP-3XL |
Cisco lists both supervisor modules as compatible with this line card |
|
Slot Plan |
Confirm slots 1, 2, 3, 4, 7, 8, 9, or 10 |
The line card must be placed in supported C9610R line-card slots |
|
Software Release |
Confirm Cisco IOS XE 17.18.1 or later support context |
Cisco documents 17.18.1 as the minimum release for C9610-LC-32CD |
|
QSFP28 Media |
Confirm 100G or 40G QSFP28 optics and cable choices |
The majority of the line-card capacity is built around QSFP28 ports |
|
Adapter Handling |
Confirm whether C9610-LC-ADPT is absent or intentionally used elsewhere |
Native C9610-LC-32CD orders should not be confused with Catalyst 9600X line cards using an adapter |

Everything from the box to the product label said authentic. No doubts.
Needed documentation for our audit. Layer23 provided it without hesitation. Wish the lead time was a bit shorter, but product quality made up for it.
Layer23 shipped ahead of the quoted lead time. Pleasant surprise. Shipping took a couple extra days, but product itself is perfect.
