Established Global IT Distributor
With over a decade of industry experience, we are a certified Cisco Partner delivering genuine enterprise networking hardware and trusted services to system integrators, ISPs, and enterprises worldwide.
C8455-G2 Description
The C8455-G2 is the lower-density member of the Cisco 8400 Series Secure Routers, a 1RU fixed platform for campus edge deployments where every port is optical. Its twelve WAN ports split into 8 x 1 GE SFP, 2 x 1/10 GE SFP+ and 2 x 10/25 GE SFP28, with no copper ports, no expansion slots and no cellular bay anywhere in the series. Forwarding runs at up to 67 Gbps with 31 Gbps of IPsec, DRAM is 32 GB by default, and the chassis carries NEBS GR-1089 and GR-63 criteria levels that put it into carrier and utility sites alongside enterprise campuses.

Product Performance
Key Features
Two 10/25 GE SFP28 ports are fixed on the chassis, so a campus edge that has outgrown 10G reaches 25G without consuming a slot or waiting for a line card, which is what the modular routers in the 8200 and 8300 lines would require.
Every one of the twelve WAN ports takes an SFP, SFP+ or SFP28 optic and none is copper, so media choice is made per port at the optics line rather than fixed by the chassis, and a mixed fiber plant does not force a media converter.
The same router accepts a 250W AC, 400W DC or 400W HVDC supply, so a campus building, a DC plant and a high-voltage DC facility all take the same part number with a different supply on the order.
Cisco lists GR-1089 and GR-63 criteria levels for the series, which opens central-office and utility cabinets that a commercial-only rating would exclude, and the -500 to 10,000 foot altitude range covers sites below sea level as well as high-altitude ones.
DRAM starts at 32 GB and storage at 64 GB with 600 GB and 2 TB options, roughly double the branch routers in the 8200 and 8300 lines, which is what supports the 5.8M route table this platform carries.
Cisco also lists 8455-G2-MX, which runs MX 19.2 and is operated from the Cisco Meraki dashboard instead of Cisco Catalyst SD-WAN Manager, so the management plane is chosen at the part number rather than configured later.
Application Scenarios
Deployed at the boundary between a campus network and its upstream circuits, terminating 1G and 10G links on SFP and SFP+ ports while presenting 25G toward the core.
Installed where the GR-1089 and GR-63 criteria levels are a condition of entry and the rack is fed from a DC or high-voltage DC plant rather than building AC.
Placed where the installation sits anywhere between -500 and 10,000 feet, a range the series is rated across without a separate derating table.

- C8455-G2 and C8475-G2 share a series, a software floor and a 5.8M route table, so the split between them is purely density: 2 versus 4 SFP28 ports and 2 versus 8 SFP+ ports, bought with 24 Gbps more forwarding and 4.25 in. more chassis depth. A campus edge terminating fewer than ten optical circuits gets no return from the larger model.
- Stepping to C8550-G2 changes what the router is for rather than how many ports it has. It drops 25 GE entirely and standardises on 12 x 10GE, but nearly triples the tunnel count to 10,000 and lifts routes to 8M, so it answers scale rather than port speed.
- SD-WAN throughput does not follow forwarding throughput across this group. C8475-G2 leads at 21.7 Gbps while C8550-G2 forwards faster at 115 Gbps but delivers only 19 Gbps of SD-WAN, so a design whose traffic is mostly overlay should size against the SD-WAN column rather than the forwarding column.
- For deciding which SKU to order, count the circuits that need 25 GE first, because that single number separates C8455-G2 from C8475-G2 and rules out C8550-G2 altogether; then check tunnel scale, since only C8550-G2 goes past 3,500. NEBS, altitude range and the optical-only faceplate are common to all three and cannot break the tie.
Selection Guide
1. When Two Twenty-Five Gig Ports Are Enough
C8455-G2 gives two SFP28 ports against the four on C8475-G2 for the same 5.8M routes and the same software floor; a campus edge whose 25G demand is a pair of core uplinks pays for 12 in. of depth and 12.5 lbs instead of 16.25 in. and 15.5 lbs.
2. Where The Tunnel Count Decides Instead Of Ports
Both 8400 models stop at 3,500 IPsec tunnels while C8550-G2 carries 10,000; an SD-WAN design whose spoke count passes 3,500 has to move to the 8500 Series regardless of how few ports it needs, since no 8400 configuration raises that ceiling.
3. DC And High-Voltage DC Sites
The 250W AC supply is one of three options alongside 400W DC and 400W HVDC on the same chassis, so site power narrows the supply rather than the router; a building that later converts from AC to a DC plant replaces the supply and keeps the same part number.
4. Choosing The Management Plane At The Part Number
C8455-G2 runs Cisco IOS XE 17.15.3 under Cisco Catalyst SD-WAN Manager 20.15.3, while 8455-G2-MX runs MX 19.2 under the Cisco Meraki dashboard on comparable hardware; an estate standardised on Meraki operations should order the MX variant, because the management plane cannot be switched after purchase.
5. Memory Headroom Runs The Other Way Here
C8475-G2 reaches 64 GB DRAM from Cisco IOS XE 17.18.3 while C8455-G2 is documented only at 32 GB; a deployment expecting feature growth that outruns 32 GB should take the larger model at order time even when the port count is not needed.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Power supply type |
Confirm whether the site feeds AC, DC or high-voltage DC, and order the 250W AC, 400W DC or 400W HVDC supply accordingly. |
The supply is selected at order time and an AC-only order cannot be wired into a DC plant. |
|
Optics for every port |
Confirm SFP, SFP+ and SFP28 optics are on the order for each port that will be used. |
All twelve WAN ports are optical cages and ship without transceivers, so an order without optics arrives unusable. |
|
Software image floor |
Confirm the image is Cisco IOS XE 17.15.3 or later and the manager is Cisco Catalyst SD-WAN Manager 20.15.3 or later. |
Staging on an earlier train leaves the router unsupported even though the hardware is installed. |
|
Management plane |
Confirm the order is the IOS XE C8455-G2 rather than the Meraki-managed 8455-G2-MX. |
The two are operated from different management systems and cannot be swapped after purchase. |
|
Storage capacity |
Confirm whether the default 64 GB is sufficient or whether 600 GB or 2 TB is required. |
Storage is selected at order time and a later change means a parts order. |
|
Rack depth and altitude |
Confirm the rack clears 12 in. of chassis depth and that the site sits between -500 and 10,000 feet. |
Depth and altitude are both fixed constraints that a survey can miss until installation day. |
