C8300-2N2S-6T Description
The C8300-2N2S-6T is a Cisco Catalyst 8300 Series Edge Platform 2RU router for branch WAN edges on 1G circuits that need room for two service modules. The router pairs two 1G SFP and four 1G RJ-45 ports with two SM, two NIM and one PIM slot, 8 GB of DRAM, and SD-WAN IPsec of up to 2 Gbps, or 1.8 Gbps on IMIX traffic, across 6,000 overlay tunnels. Without an HSEC license, encrypted traffic is held to 250 Mbps one way and 1,000 secure tunnels.

Product Performance
Key Features
Plain IPv4 forwarding runs at up to 19.7 Gbps with 1400-byte packets, but IPsec tops out near 2 Gbps in either software mode. On mixed branch traffic averaging 352 bytes, the router encrypts 1.8 Gbps in SD-WAN mode and 1.9 Gbps in autonomous mode, and those are the numbers to size tunnels against.
The SM slots take single-wide modules as well as double-wide modules that only the 2RU Catalyst 8300 chassis accepts, including the C-SM-40P8M2X 50-port Layer 2 switch module and the SM-X-72FXS analog voice module. NIM carriers in the SM slots take the NIM count from two to six.
The router ships with service-oriented core allocation, which reserves cores for KVM and Docker applications next to packet forwarding. The data plane heavy profile trades that away: on this 8-core platform it removes container resources entirely.
With NAT, NGFW, IPS, URL filtering and AMP all enabled, direct internet traffic runs at 2.3 Gbps under the IOS XE 17.12.2 firewall EMIX profile. A split of half IQDF-encrypted SD-WAN traffic and half inspected internet traffic reaches 2.8 Gbps.
Two PWR-CC1-650WAC supplies come installed, and neither feeds PoE. PoE ports on NIMs or SMs need at least one PWR-CC1-1000WAC in a supply bay, which gives a 500W budget for modules such as the C-NIM-1M with its 90W port.
Fitting PWR-CC1-650WDCR reverse-airflow DC supplies brings the chassis into NEBS compliance, and the C8300-FAN-2R-R fan assembly comes with them. Typical sound pressure rises from 59 dBA to 63 dBA in that build.
Application Scenarios
At a branch served by gigabit fiber or copper circuits, the router terminates the WAN on its 1G ports while a 50-port switch module connects the office floor and a UCS-E compute module runs local virtual network functions.
Retail or clinic sites that cannot lose connectivity add a 5G or LTE Advanced Pro pluggable in the PIM slot, so the router keeps an SD-WAN path open over cellular when the wired circuit fails.
Hotels and healthcare buildings that still run analog handsets and fax machines connect them to a 72-port FXS module in the double-wide SM position, with SRST keeping local calling up if the link to the call controller drops.

C8300-2N2S-6T and C8300-2N2S-4T2X share the 2RU chassis, slots and dual 650W supplies, but C8300-2N2S-6T has two 1G SFP ports in place of 10G SFP+ and stops at 2 Gbps of SD-WAN IPsec against 18.8 Gbps. A site with 10G circuits, or encrypted traffic above 2 Gbps, belongs on C8300-2N2S-4T2X, which carries 7.6 Gbps on IMIX against 1.8 Gbps. C8300-1N1S-6T has the same six 1G ports and the same 2 Gbps IPsec in a 1RU chassis with one SM and one NIM slot, so a branch that needs only one service module can move down to it. Moving down also halves the PoE budget for module ports, from 500W to 250W with the PoE supply fitted.
Ordering Checklist
- Subscription and software mode: Add a Cisco DNA Essentials or Advantage subscription, or ROUT-P-C8300-E-7Y, under the chassis or on an L-DNA-C8300 line. Routing Essentials orders only with IOSXE-AUTO-MODE and carries no voice entitlements.
- Voice license tier: Choose Cisco DNA Advantage when the order includes SRST or any voice module such as SM-X-72FXS. CUBE alone needs Cisco DNA Essentials at minimum.
- HSEC license: Confirm C8000-HSEC on a hardware-attached subscription, or C8000-HSEC-DNA with L-DNA-C8300. Without HSEC the router stops at 1,000 secure tunnels and 250 Mbps of one-way encrypted traffic.
- Bandwidth tier: A Tier 2 bandwidth license unlocks the full platform throughput of C8300-2N2S-6T. A Tier 1 license keeps one-way encrypted traffic under 250 Mbps, or 500 Mbps aggregate from IOS XE 17.14.1a.
- Module lines: Select the NIMs, SMs and PIM on the chassis order. C8300-NIM-BLANK, C8300-SM-BLANK and C8300-PIM-BLANK are added only for a slot type with no module ordered.
- DIMM and M.2 lines: MEM-C8300-8GB and M2USB-16G are the defaults; change them to MEM-C8300-16GB, MEM-C8300-32GB, M2USB-32G or SSD-M2NVME-600G when route scale or hosted applications need more.
- Power supplies and cords: Swap a default PWR-CC1-650WAC for the 1000W AC PoE supply, PWR-CC1-1000WAC-P on the chassis order or PWR-CC1-1000WAC= as a spare, when PoE modules are ordered, or for PWR-CC1-650WDC at DC sites. Each supply needs a country-specific power cord.

We compared total landed cost across vendors. Layer23 came out ahead.
The consistency across multiple orders is what sets Layer23 apart.
We’ve shipped sensitive equipment ourselves. Layer23 packs better than most.
Competitive bid. Included the rack mounts and power cables. Good value.
Now that’s what I call a router! Shiny and new. Thanks for the quick delivery.
