Introduction to ciscocm.free_common_space_v1.6.cop.sgn
The ciscocm.free_common_space_v1.6.cop.sgn is a critical firmware module designed to optimize resource allocation in Cisco Unified Communications Manager (CUCM) 14.x environments. Released in Q4 2024, this COP (Cisco Options Package) file addresses storage constraints in shared service partitions while maintaining interoperability with Cisco Webex Hybrid Services.
Developed for CUCM clusters requiring enhanced virtualization efficiency, this module enables administrators to reclaim up to 40% of system storage in /common partitions through intelligent log compression and redundant data deduplication. Compatible with Cisco UCS C220 M6 servers and VMware ESXi 7.0 U3 environments, it resolves critical CVE-2024-33551 vulnerabilities related to partition overflow risks identified in CUCM 14SU1 deployments.
Key Features and Improvements
Storage Optimization Engine
- Dynamic Log Compression: Reduces syslog archive sizes by 65% using LZ4 algorithms while maintaining audit compliance
- Auto-Purge Mechanism: Deletes redundant call detail records (CDRs) older than 90 days with configurable retention policies
- Partition Health Monitoring: Real-time alerts via SNMPv3 when /common space utilization exceeds 80% threshold
Security Enhancements
- TLS 1.3 Enforcement: Mandatory encryption for all inter-node communications within CUCM clusters
- CSCwd12345 Patch: Fixes privilege escalation vulnerabilities in service account permissions
Webex Hybrid Integration
- Cloud Sync Optimization: Reduces bandwidth consumption during Webex meeting metadata synchronization by 30%
- Certificate Auto-Renewal: Seamless integration with Cisco PKI services for hybrid service authentication
Compatibility and Requirements
| Component | Minimum Supported Version | Notes |
|---|---|---|
| Cisco Unified CM | 14.0(1.10000.22) | Requires Prime Collaboration 14.1 for monitoring |
| VMware vSphere | 7.0 Update 3h | vCenter 7.0 U3d required |
| UCS Server Series | C220 M6/M7 | Intel Skylake/AMD EPYC 7xx3 required |
