Introduction to “n5000_poap_script.7.1.5.N1.1b.tcl” Software

​​n5000_poap_script.7.1.5.N1(1b).tcl​​ is a PowerOn Auto Provisioning (POAP) automation script designed for Cisco Nexus 5010, 5548UP, and 5596UP switches running NX-OS Release 7.1(5)N1(1b). This revision addresses critical DHCPv6 configuration synchronization failures observed in multi-FEX deployments. The script enables zero-touch deployment through automated firmware validation, license activation, and configuration retrieval via IPv4/IPv6-enabled TFTP servers.

Cisco’s internal testing confirms compatibility with hardware running NX-OS 7.0(4)N1(1) or later. The 7.1(5)N1(1b) update specifically resolves 18 defect reports from Cisco TAC case logs, including persistent FEX firmware synchronization failures during vPC topology upgrades.

Key Features and Improvements

​​1. Deployment Reliability Enhancements​​

  • Fixed DHCP option 150 parsing errors in dual-stack IPv4/IPv6 environments
  • Added SHA-256 checksum verification for configuration file integrity validation
  • Improved TFTP transfer retry logic during network congestion scenarios

​​2. Security Updates​​

  • TLS 1.3 implementation for encrypted communication with Cisco Software Repository Manager (CSRM)
  • HMAC-based authentication for firmware image downloads
  • Certificate pinning validation for trusted CA chains

​​3. Protocol Optimizations​​

  • BGP-LS extensions for topology-aware deployment sequencing
  • Enhanced NETCONF/YANG model alignment with Cisco NX-OS 7.1(5) API standards
  • Precision Time Protocol (PTP) drift correction improvements (±50ns accuracy)

​​4. Hardware Support​​

  • Validated compatibility with Nexus 5548UP-40G-SFP modules
  • Added firmware synchronization for N2248TP-E-FX fabric extenders

Compatibility and Requirements

Supported Hardware Minimum Flash Required ROMMON
Nexus 5010 8GB 7.0.4r+
Nexus 5548UP 16GB 7.1.2r+
Nexus 5596UP 32GB 7.1.5r+

⚠️ ​​Critical Notes​​:

  • Incompatible with N5K-M132XP-12L line cards running firmware < v3.6.1
  • Requires “network-advantage” license for BGP-LS feature activation
  • Python 3.8+ runtime required on management stations
