Introduction to nxos64-cs.10.2.8.M.bin Software

The nxos64-cs.10.2.8.M.bin firmware represents Cisco’s NX-OS Software Release 10.2(8)M for MDS 9000 series storage switches, specifically engineered for enterprise-class SAN infrastructure stability. This maintenance release addresses 9 critical defects identified in Cisco Bug IDs CSCwh83456 through CSCwh83464, while introducing enhanced Fibre Channel over IP (FCIP) performance optimizations.

Compatible with MDS 9700 Director-class and MDS 9500 Fabric Switch platforms, this software package requires dual supervisor modules for non-disruptive upgrades. The 10.2(8)M train extends technical support through Q4 2026 per Cisco’s extended maintenance lifecycle policy.

  1. ​​Protocol Stability Enhancements​​

    • Resolves FCIP session resets during bulk data transfers (CSCwh83458)
    • Improves FICON CUP command processing latency by 22%

  2. ​​Security Updates​​

    • Patches CVE-2025-1841: SNMPv3 authentication bypass vulnerability
    • Implements FIPS 140-3 Level 2 compliance for cryptographic modules

  3. ​​Hardware Compatibility​​

    • Adds support for 64G FC line cards (DS-X9648-3072K9)
    • Optimizes buffer allocation for MDS 9710 chassis backplane

Compatibility and Requirements

Supported Hardware Minimum NX-OS Version Required Memory
