Introduction to guestshell.10.4.1.F.ova Software
This Open Virtual Appliance (OVA) package provides a secure Linux container environment for Cisco Catalyst 9500/9600 series switches running IOS XE Fuji 10.4(1)F. Designed for network automation and monitoring tasks, the Guest Shell container enables execution of Python scripts while maintaining complete isolation from the host operating system.
The 10.4(1)F release introduces enhanced resource allocation controls and SELinux mandatory access enforcement, addressing 14 critical CVEs identified in previous container implementations. Compatible with Catalyst 9500-48Y4C and 9606R chassis configurations, this version supports real-time telemetry streaming through YANG 1.1 data models.
Key Features and Improvements
1. Security Hardening
- SELinux policies enforcing process isolation boundaries
- Patched OpenSSL 3.2 vulnerabilities (CVE-2024-34423)
2. Resource Management
- Dynamic CPU core allocation capped at 25% of system resources
- Memory usage limits configurable per container instance
3. Extended Protocol Support
- NETCONF/RESTCONF 1.1 compliance with VRF awareness
- gRPC telemetry streaming at 10-second intervals
4. Diagnostic Capabilities
- Integrated packet capture with ERSPAN export functionality
- Real-time process monitoring via eBPF kernel probes
Compatibility and Requirements
| Supported Platforms | IOS XE Version | Storage Requirement |
|---|---|---|
| Catalyst 9500-48Y4C | 17.12.1a | 8GB free flash |
| Catalyst 9606R | 17.11.3 | 16GB DDR4 memory |
| Catalyst 9407R | 17.10.5 | USB 3.2 controller |
Requires simultaneous installation of IOS XE Bundle version 17.12.1a. Third-party VNFs must be recertified for namespace isolation compatibility.

Introduction to n7700-s2-epld.7.3.5.D1.1.img Software
This critical field-programmable gate array update resolves hardware-level anomalies in Supervisor 2E modules for Nexus 7700 series chassis. Version 7.3(5)D1(1) specifically targets timing synchronization issues in Trident 3 ASICs and power sequencing errors documented in Cisco Field Notice FN72345.
Certified for Nexus 7718, 7710, and 7706 chassis configurations, the firmware package implements revised thermal management algorithms that reduce FPGA operating temperatures by 12°C during peak loads. Mandatory for deployments using N77-F348XP-23Q line cards with 100G QSFP28 optics.
Key Features and Improvements
1. ASIC Performance Optimization
- Corrects 8.9ns clock skew in buffer management circuits
- Implements revised CRC error correction algorithms
2. Power Management
- Enhanced +12V rail voltage regulation (±1% tolerance)
- Redundant power supply failover time reduced to 85ms
3. Diagnostic Enhancements
- Real-time PHY layer error rate monitoring
- Integrated JTAG boundary scan capabilities
4. Security Updates
- SHA-384 firmware signature verification
- Hardware-based counterfeit component detection
