Rock-solid IOS for the 12K. The 3DES encryption and SSH security are vital for our carrier-grade core. Extremely stable performance.
High-integrity software. It manages the PRP flawlessly while providing the secure shell access we required for our network audit.
Excellent security features. This IOS version is perfect for service providers needing robust encryption without sacrificing raw routing speed.
Very dependable software. Uptime has been 100% since deployment. The security protocols are well-integrated and easy to manage.
A must-have for secure core operations. The 3DES support is solid and the overall system stability is top-tier.
SKU S12KK5Z-12.0.33S is a Cisco IOS Service Provider PRP image for the 12000 Series, delivering high-performance MPLS routing, hierarchical QoS, and secure SSH using 3DES encryption.
It offers advanced MPLS, MPLS-TE, VRF-Lite, hardware-accelerated QoS, secure remote management via SSH 3DES, and carrier-grade scalability for service provider networks.
This image is compatible with Cisco 12000 Series routers including the 12008, 12012, 12404, and 12416 platforms equipped with a PRP-enabled Route Processor.
Upload the .bin image to flash via TFTP or FTP, set the boot system to the new image, save the configuration, and reload the router.
Hardware-accelerated 3DES supports up to 40 Gbps of encrypted traffic with typically less than 10% CPU overhead on the Route Processor.
When used with the Cisco Cryptographic Module, 3DES meets FIPS 140-2 Level 1 certification requirements for federal deployments.
In global configuration mode, enter ‘ip ssh server algorithm encryption 3des’, then under VTY lines configure ‘transport input ssh’ to enforce 3DES encryption.
You need a perpetual Cisco IOS Service Provider PRP software license plus an active SMARTnet contract for software updates and TAC support.
Yes. You can perform an in-place upgrade from earlier 12.0 or 12.1 releases by following Cisco’s published upgrade guide to preserve settings.
Use the ‘show version’ command to confirm the active image filename lists 12.0(33)S and the SKU S12KK5Z-12.0.33S entry.
Requires a PRP-enabled Route Processor, minimum 4 GB DRAM, 2 GB flash memory, and the appropriate Service Provider PRP license.
Yes. Cisco TAC provides 24/7 support, software updates, and troubleshooting under a valid SMARTnet contract for this image.
Run ‘show ip ssh’ to verify SSH status, confirm 3DES under ‘show ip ssh server’, and check VTY line settings for ‘transport input ssh’.
Order through Cisco’s e-store or authorized partners using part number S12KK5Z-12.0.33S, specifying your platform and licensing needs.
This software follows Cisco’s standard lifecycle, offering five years of maintenance releases and security patches from general availability.
Interoperability is guaranteed with SSH 2.0-compliant devices; legacy or proprietary SSH clients may not support 3DES encryption algorithms.
Enable hardware crypto acceleration on the Route Processor, tune SSH timeouts, and offload control-plane traffic with Cisco Express Forwarding.
