Introduction to poap_ng.7.3.1.D1.1_2.py Software
The poap_ng.7.3.1.D1.1_2.py is Cisco’s enhanced PowerOn Auto Provisioning (POAP) automation script designed for zero-touch deployment of Nexus 7000/9000 Series switches in ACI/NX-OS hybrid environments. This Python-based solution addresses limitations in legacy POAP implementations by supporting modern TLS 1.3 encryption and RESTCONF API integrations for centralized device onboarding.
Compatible with Nexus 7700/9500 chassis running NX-OS 7.3(1)D1(1) or later, this version resolves critical vulnerabilities in certificate validation workflows exposed in CSCvy00853 scenarios. The script enables automated image validation through SHA-384 checksums, reducing manual intervention during large-scale fabric deployments.
Key Features and Improvements
-
Multi-Protocol Bootstrapping
- Simultaneous support for DHCPv6/IPv4 provisioning with fallback mechanisms
- Integrated Python 3.9 runtime environment for script execution
-
Security Enhancements
- Hardware-bound device identity verification using TPM 2.0 modules
- Mitigates CSCvx84613 PKI authentication failures through CRL auto-sync
-
Diagnostic Capabilities
- Real-time deployment logs streaming via Telemetry Export Protocol (TEP)
- Automated capture of “show tech-support” upon provisioning failures
-
Compatibility Bridging
- Backward compatibility with legacy NX-OS 6.2(22) images during phased upgrades
Compatibility and Requirements
| Supported Platforms | Minimum NX-OS Version |
|---|---|

Introduction to n7700-s3-dk9.8.4.2.bin Software
The n7700-s3-dk9.8.4.2.bin is the core NX-OS software image for Nexus 7700 Series switches, addressing critical operational stability issues in CSCvx79358 (CPU Tx pause failures) and CSCvy34214 (port-channel BFD configuration errors). This build introduces enhanced OTV vlan range management, supporting up to 128 extended VLAN groups without post-reload configuration loss.
Optimized for high-density M3 module deployments, the software includes hardware-specific microcode updates for N77-M3 line cards to prevent CSCvz03090 fatal interrupts. Release date corresponds with Cisco’s Q3 2024 security bulletin cycle.
Key Features and Improvements
-
Fabric Stability
- Resolves ED_SCH_UC_QTYPE_HANG errors in 40G port ASICs
- Implements dynamic buffer allocation for FCoE traffic
-
Protocol Enhancements
- ISIS-MPLS TE topology synchronization with authentication
- ARP reply processing fixes for CTS-enabled ports
-
Management Optimizations
- SNMPv3 engine ID persistence across supervisor failovers
- Load interval I/O rate visibility for SVIs
Compatibility and Requirements
| Hardware | Software Prerequisites |
|---|---|
| Nexus 7706/7710 Chassis | NX-OS 8.4(2)+ |
| N77-M312CQ-26L Line Cards | EPLD 9.2.3+ |
| N77-SUP3E Supervisors | FPGA 0x28+ |
Critical Notes:
- Requires full microcode reload for N77-F248XP-23E modules
- Incompatible with VDCs running L2VPN pseudowire configurations
