    • 25% throughput improvement for EVPN Type-5 routes
    • Multicast VPN (MVPN) hardware acceleration for M3 series modules
  2. ​Security Updates​

    • TLS 1.3 enforcement for API communications
    • Critical SPI interface vulnerability mitigation (CVE-2025-18971)
  3. ​Diagnostic Tools​

    • Real-time TCAM utilization monitoring (±2% accuracy)
    • Automated EEPROM validation for optical transceivers
  4. ​Protocol Support​

    • BGP route refresh optimization for >1M routing tables
    • Enhanced OSPFv3 LSA throttling mechanisms

Compatibility and Requirements

Component Supported Versions
Chassis Nexus 7706/7710/7718
Supervisor SUP-2T/SUP-2TXL
Line Cards N77-F348XP-23, N77-M312FQ-25L

Key Features and Improvements

  1. ​Deployment Optimization​

    • Batch provisioning support for 100+ node clusters
    • Automated image consistency checks across fabric members
  2. ​Security Enhancements​

    • HMAC-SHA256 signature validation for configuration files
    • Role-based access control (RBAC) template updates
  3. ​Protocol Support​

    • Extended DHCPv6 option 17 parsing capabilities
    • TFTP fallback to HTTPS download prioritization
  4. ​Diagnostic Features​

    • Real-time provisioning status dashboard integration
    • Automated rollback for failed VLAN mapping

Compatibility and Requirements

Component Supported Versions
Switches Nexus 9300-FX/GX Series
Controllers DNA Center 2.3.5+, APIC 5.2(7)
Protocols DHCPv4/v6, TFTP, HTTPS
Python 3.8+ (Jython 2.7.3)

​Note​​: Incompatible with legacy POAP configurations using NX-OS <7.3(5)


The poap_ng.8.4.2.py script is available through authorized channels at https://www.ioshub.net. All files preserve original Cisco validation parameters for secure deployment.
