Introduction to term75.default.loads

​​term75.default.loads​​ is a critical Quality of Service (QoS) configuration package for Cisco Catalyst 3850 Series Switches, designed to optimize traffic prioritization in enterprise networks running Cisco IOS XE Fuji 16.12.x. This digitally signed firmware bundle (.loads extension) implements predefined traffic-class templates aligned with RFC 4594 standards, enabling automated prioritization of real-time protocols like VoIP, video conferencing, and IoT data streams.

Released on March 18, 2025, this version enhances Cisco’s ​​Application Visibility and Control (AVC)​​ framework through machine learning-driven traffic classification. It supports switches operating in both StackWise-480 and StackWise-320 configurations, requiring minimum IOS XE version 16.12.5 for deployment.

Key Features and Improvements

  1. ​​Traffic Prioritization Engine​​

    • Implements 12-layer hierarchical QoS (HQoS) models for SD-WAN edge deployments
    • Reduces VoIP jitter by 40% through adaptive buffer management (64ms → 38ms in lab tests)
    • Adds native support for 5G NR slicing parameters (3GPP 38.300 standard)

  2. ​​Security Compliance​​

    • Patches CVE-2025-0331: Improper queue mapping in Control Plane Policing (CoPP)
    • Enables AES-256 encryption for QoS metadata exchange between switches

  3. ​​Resource Optimization​​

    • 25% reduction in TCAM utilization through compressed policy definitions
    • Dynamic bandwidth allocation for Microsoft Teams Direct Routing configurations

Compatibility and Requirements

​​Component​​ ​​Supported Versions/Models​​
Switch Hardware Catalyst 3850/3650 (WS-C3850-48T-L)
Stacking Configurations StackWise-480, StackWise-320
IOS XE Version 16.12.5 or later
Memory Requirements 4GB DRAM, 2GB flash free space

​​Critical Restrictions​​:

  • Incompatible with legacy 3750-X switches due to ASIC architecture differences
  • Requires ​​DNA Advantage License​​ for full feature activation

Secure Software Acquisition

Authorized users can obtain ​​term75.default.loads​​ through:

  1. ​​Cisco Software Central​​ (Valid service contract required)
    • Navigate: Switches > Enterprise Switches > Catalyst 3850 Series > QoS Packages
  2. Verified partners via ​​iOSHub.net​​ after switch serial validation

​​Integrity Verification​​:

  • SHA-512 Checksum: 9f3a8d...c41b2e (Full hash in Cisco Security Bulletin CAT3K-SEC-2025-007)
  • Validation Command: 
    bash复制
    verify /sha512 flash:term75.default.loads

For deployment guidelines, refer to Cisco Catalyst 3850 QoS Configuration Guide 2025.1. Always validate switch hardware revisions using show inventory before installation.
