Cisco NCS 4200 RSP3 IOS XE Universal Encryption Software

Operate an NCS 4200 RSP3 platform on the Cisco IOS XE Universal 17.12 software release with payload encryption. SNCS42R3K91712 identifies the crypto-capable Universal edition associated with that platform. The payload-encryption designation matters where an IOS XE image must include cryptographic functionality rather than a non-encryption software variant. This item is platform-specific software, not a general IOS XE selection for arbitrary Cisco systems. NCS 4200 RSP3 is the supported platform designation carried by the product name. Match that designation before selecting the item because the release and encryption designation apply to that RSP3 environment. IOS XE Universal identifies the software edition, while payload encryption identifies the encryption-capable variant. Keeping those terms together avoids confusing a platform reference with a generic operating-system request. The software selection is tied to the named processor platform. Use the 17.12 release designation when maintaining a consistent IOS XE version on applicable NCS 4200 RSP3 systems. This software designation addresses deployments that require the Universal image's payload-encryption capability. The ordering code distinguishes this combination of platform, release, and encryption variant from records that name only IOS XE or only NCS 4200. It focuses on operating software selection for the named RSP3 platform rather than chassis, interface, or processor hardware characteristics.
