Cisco ASAv vCenter Deployment Manifest (asav-vi.mf) Verification File Download Link
Introduction to asav-vi.mf
The asav-vi.mf file serves as the deployment manifest for Cisco ASAv virtual appliances in vCenter environments. This critical verification document contains SHA-256 cryptographic hashes and file metadata ensuring package integrity for ASAv OVF templates distributed through Cisco’s official channels.
Specifically designed for vSphere 7.0+ deployments, this manifest works with the asav-vi.ovf template to validate all components in the ASAv installation package, including virtual disk images and configuration scripts. It forms an essential part of Cisco’s secure software distribution chain for virtualized security appliances.
Technical Specifications
Validation Features
- Multi-File Integrity Checking: Cross-verifies 7 critical deployment files
- OVF Template Compliance: Ensures VMware compatibility standards
- Cryptographic Signatures: Supports Cisco PKI infrastructure validation
Security Enhancements
- FIPS 140-3 Compliant Hashing
- Timestamped Verification
- Tamper-Evident Formatting
Compatibility Requirements
| Category | Supported Platforms |
|---|---|
| vCenter Versions | 7.0 U2+/8.0+ |
| ESXi Hosts | 6.7 U3+/7.0+ |
| Security Tools | Cisco CSP 2.4+ |
| Validation Systems | OpenSSL 3.0+ |
Usage Notes
- Mandatory for secure deployments in regulated industries
- Requires Cisco Trust Verification Client 5.2+
- Incompatible with legacy MD5 verification systems
Package Validation Process
The manifest enables automated integrity checks during vCenter template imports:
- vSphere Client compares file hashes against asav-vi.mf entries
- Cryptographic signatures validate Cisco authorship
- Deployment proceeds only after full verification
