C8225-G2 Description
The C8225-G2 is the security-services tier of the all-gigabit Cisco 8200 Series desktop routers. Its faceplate is 2x 1/10 GE SFP+ plus eight 1 GE copper ports split as two WAN, two Flex and four LAN, with no cellular bay, no module slot and no PoE-capable supply anywhere in the configuration. It shares that faceplate exactly with C8221-G2, and the pair differ only in DRAM at 16 GB against 8 GB and Threat protection at 2.4 Gbps against 1 Gbps. Forwarding, IPsec and SD-WAN are 19, 5 and 4 Gbps on both. The chassis is a 5 lb desktop unit running on a 66W AC adapter, and the platform starts at Cisco IOS XE Release 26.1.2.

Product Performance
Key Features
C8221-G2 carries exactly the same ports, adapters, chassis and software floor; the only reasons to choose this SKU are 16 GB of DRAM instead of 8 GB and 2.4 Gbps of Threat protection instead of 1 Gbps.
Cisco lists no PoE-capable supply for this model, so all ten ports are data-only; a branch needing to power an endpoint has to move to the mGig models in the series or add an injector.
The two 1/10 GE SFP+ cages accept 1 GE or 10 GE optics, so the same router terminates a gigabit copper handoff through an SFP or a 10 GE fibre circuit without changing part number.
This model starts at Cisco IOS XE Release 26.1.2 while C8235-G2 and C8231-G2 start at 17.18.1, so the all-gigabit and multigigabit halves of the series sit in different release families.
Typical consumption is 21W against 26.70W and 27.11W for the mGig models, which matters where several routers share a small UPS or a metered circuit.
The chassis is rated to 45 degrees C at sea level, but Cisco publishes 40 degrees C once the dust and liquid cover is fitted, so a protected install trades thermal headroom for ingress protection.
Application Scenarios
Deployed where every local device and circuit runs at 1 GE and the SFP+ cages carry the uplink, without powered endpoints or cellular backup.
Installed with the dust and liquid cover in workshop, retail back-of-house or light-industrial spaces, operating inside the reduced 40 degrees C envelope.
Placed where NAT, firewall, intrusion prevention, URL filtering and malware protection run on the router rather than at a hub, using the 2.4 Gbps inspection tier.

Cisco IOS XE Release 26.1.2 |
Cisco IOS XE Release 17.18.1 |
- C8225-G2 and C8221-G2 are the same product on every line the data sheet publishes except two. Ports, adapters, typical draw, chassis, temperature range and software floor are identical; DRAM is 16 GB against 8 GB and Threat protection is 2.4 Gbps against 1 Gbps.
- Because forwarding, IPsec and SD-WAN are 19, 5 and 4 Gbps on both, the premium buys nothing for a branch that routes and encrypts without running the full inspection stack locally. The decision is a single question about where security services execute.
- C8235-G2 shows what the multigigabit half of the series adds for the same 16 GB and 2.4 Gbps: every copper port moves to 2.5 GE, a PIM cellular bay appears, and a 120W PoE budget becomes available, at the cost of 2 lbs, 6W more typical draw and a different software train at 17.18.1.
- For deciding which SKU to order, settle whether inspection runs on the router, which separates this model from C8221-G2; then check whether any endpoint needs more than 1 GE or any power at all, since both of those move the order to C8235-G2 and a different release family.
Selection Guide
1. When One Gigabit Of Inspection Is The Ceiling
C8221-G2 matches this router on every port, adapter and chassis figure and differs only at 1 Gbps of Threat protection and 8 GB of DRAM; a branch inspecting at a regional hub gets identical routing and encryption without paying for headroom it will not reach.
2. No Path To A Powered Port
Cisco lists no PoE-capable supply for this model or its twin, so an endpoint needing power means either an injector or a move to C8235-G2; this is a permanent property of the configuration rather than an adapter choice.
3. Twenty-Six Point One Two Against Seventeen Point Eighteen
The all-gigabit models start at Cisco IOS XE Release 26.1.2 while the multigigabit models start at 17.18.1; an estate standardised on the 17.18 train has to qualify a new release family before this router enters service, and the reverse is true moving the other way.
4. Where Gigabit Copper Is Genuinely Enough
Eight 1 GE ports against the eight 2.5 GE ports of C8235-G2 costs nothing where local devices are gigabit-attached, and saves 2 lbs and roughly 6W of typical draw per site across a large branch estate.
5. Ingress Protection Narrows The Thermal Band
Fitting the dust and liquid cover drops the rated ceiling from 45 to 40 degrees C, so a protected installation in a warm space needs the same thermal check as the uncovered multigigabit models rather than the wider band the bare chassis carries.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Inspection tier at order time |
Confirm 2.4 Gbps of Threat protection is required rather than the 1 Gbps of C8221-G2. |
The two SKUs are otherwise identical and Cisco documents no upgrade path between them. |
|
Powered endpoints |
Confirm no endpoint will draw power from the router. |
No PoE-capable supply is listed for this model, so a powered device needs an injector or a different SKU. |
|
Software train readiness |
Confirm the estate can run Cisco IOS XE Release 26.1.2 and Cisco Catalyst SD-WAN Release 26.1.2. |
The all-gigabit 8200 models do not run the 17.18 family the multigigabit models use. |
|
Uplink optics |
Confirm 1 GE or 10 GE SFP optics are on the order for the two SFP+ cages. |
The cages ship without transceivers and the copper ports cannot carry the uplink. |
|
Dust and liquid cover |
Confirm whether the cover is required and that the site stays inside 40 degrees C if it is fitted. |
The cover reduces the rated ceiling from 45 to 40 degrees C. |
|
Rack-mount tray |
Confirm the rack-mount tray is on the order if the chassis will be racked. |
Cisco publishes the racked dimension only with that tray, which is a separate accessory. |
